ASAP operating principles

Illustration of ASAP technique:

The ASAP technique depends on heated nitrogen desolvation gas to vaporize the sample and corona discharge for ionization. It can ionize low-polarity compounds not amenable to electrospray (ESI), atmospheric pressure chemical ionisation (APCI), and atmospheric pressure photoionization (APPI), at high sensitivity. You can also use the technique to analyze complex samples, without needing to extensively prepare them.

The ASAP device is designed to modify an existing atmospheric pressure ionization (API) source, and you can use it as a substitute for electron-ionization (EI) or chemical-ionization (CI) vacuum, solids-probe analyses.

Installing the outer assembly

Requirement: Calibrate the instrument before you fit the ASAP. To do so, follow the calibration procedures in the MassLynx online Help (see page 2-4).

To install the outer assembly:

1. Remove any existing probe from the source housing, see the instrument’s Operator’s Overview and Maintenance Guide.

2. Where applicable, blank off the nebulizing gas outlet on the front panel using the supplied blanking plug.

3. Fit an APCI corona pin into the source, adjusting it to point to the sample cone.

Requirement: If you are using the LockSpray interface, use the supplied ESCi® corona pin to avoid making contact with the lock-spray baffle.

4. Holding the outer assembly by the body cover, fit it into the source housing and secure it with the attachment thumbscrews.

Tip: The Xevo version of the probe does not have thumbscrews. To secure it, rotate the locking ring clockwise until tight.

Result: The outer assembly is now ready to accept the inner probe.

Warning: For instruments with a nebulizing gas outlet on their front-panel, to avoid excessive gas escaping into the work environment, blank off the instrument nebulizing gas outlet.

Preparing the ASAP for use

Calibration

Normal practice is to calibrate the instrument before you fit the ASAP. To do so, follow the calibration procedures in the MassLynx online Help.

However, if your source contains a lock-spray reference probe, you can calibrate the instrument after fitting the ASAP by using the reference probe to introduce the calibration reference solution.

A suitable calibration compound for all compatible instruments is sodium formate.

Optimizing the probe position

You can optimize the position of the capillary end relative to the sample cone and corona pin by adjusting the micrometer on the source housing. A good starting position for the capillary end is mid-way between the two.

You can move the capillary end closer to the sample cone and corona pin by rotating the adjuster knob of the inner probe, ensuring that the capillary end clears the rotating lock-spray baffle (if fitted). If the baffle is not fitted, you can move the capillary end closer to the sample cone and corona pin to achieve better sensitivity. In this case, use the APCI corona pin supplied with your instrument.

You can also make fine adjustments to the probe position as the sample vaporizes, using both controls while monitoring the sample intensity of a suitable compound in the MassLynx Tune window. Once you find the optimal position, you can use it when analyzing subsequent samples.

Tip: You cannot adjust the probe position when using the Xevo version of the probe. It is designed such that the capillary end is already in the correct position for optimal sensitivity.

Baking the source

Because the ASAP technique is highly sensitive, you should “bake out” the source (with the inner probe fitted) after installing it on an instrument.

2-2 Using the ASAP

Page 21: Atmospheric Solids Analysis Probe - Waters Corporation · 2012-01-10 · Inserting the inner probe Refer to the figure on page 1-8 while following this procedure. If you are using

After the first installation, bake the source overnight using the settings shown below. On subsequent installations, baking for one hour reduces the presence of background ions to a minimum.

See page 2-7 for details on the importance of baking out.

Loading samples

Load samples onto the exposed end of a sealed glass capillary before fitting the capillary into the inner probe (see page 1-7).

Solid samples

Load the sample by rubbing the capillary gently across the surface of the solid, removing excess sample with a tissue.

Note, however, that using a tissue creates a background spectrum. You can compensate for this unwanted effect by obtaining a separate spectrum from the tissue and subtracting it from the sample spectrum. Alternatively, in an extraction hood, blow the excess sample from the capillary end using a stream of nitrogen.

Liquid samples

Load the sample by dipping the capillary end in the liquid, removing as much liquid as possible with a tissue.

Note, however, that using a tissue creates a background spectrum. You can compensate for this unwanted effect by obtaining a separate spectrum from the tissue and subtracting it from the sample spectrum. Alternatively, in an extraction hood, blow the excess sample from the capillary end using a stream of nitrogen.

Recommended bake-out settings:

Source Temp 150 °C

Desolvation Gas Flow 1200 L/h

Desolvation Gas Temp 400 to 500 °C

Warning: To avoid puncture injuries, do not handle broken capillary ends. Glass capillaries can break easily.

Loading samples 2-3

Page 22: Atmospheric Solids Analysis Probe - Waters Corporation · 2012-01-10 · Inserting the inner probe Refer to the figure on page 1-8 while following this procedure. If you are using

Samples in solution

Follow the procedure for liquid samples, or apply a 1-µL amount to the capillary end using a syringe or pipette.Use a fresh capillary to reduce contamination. If doing so is not practical, heating to 500 ºC will clean the capillary for most volatile and semi-volatile samples. You can reduce cooling time by operating the instrument with a desolvation gas flow of 1200 L/h and gas temperature of 50 ºC.

Analyzing samples

Preparing to acquire data

Before acquiring data from a loaded sample, set your instrument to operate in ESCi mode. To do so, in the MassLynx Tune window, click Ion Mode > ESCi.

The starting temperature for the desolvation gas heater is sample-dependent, although a temperature between 50 ºC and 100 ºC generally applies. When the heater reaches the starting temperature, you can vaporize the sample by gradually increasing the temperature, separating the mixtures by boiling point. If obtaining a vaporization profile of the sample is unnecessary, you can set a higher temperature. Although temperatures from 100 ºC to 350 ºC are typical, you can nevertheless specify higher temperatures for less volatile samples. Note, however, that higher temperatures can require increasing the lock mass reference flow rate to improve the stability of the reference peak.

Tip: The desolvation temperature readback value displayed in the Tune window measures temperature only at the desolvation heater block. The actual desolvation gas temperature around the capillary end depends on the desolvation gas flow rate, the heater temperature selected, and the probe position.

Recommended starting parameters

Parameter Value

Source temperature 120 ºC

Sample cone 30 V (requires tuning for optimum sensitivity)

Corona current 5 µA (requires tuning for optimum sensitivity)

Desolvation gas flow rate 500 to 1200 L/h

Desolvation gas heater 50 to 450 ºC (sample dependent)

Page 23: Atmospheric Solids Analysis Probe - Waters Corporation · 2012-01-10 · Inserting the inner probe Refer to the figure on page 1-8 while following this procedure. If you are using

Acquiring data

To ensure good results and obtain exact mass measurements throughout the vaporization profile of the sample, begin an acquisition before inserting the inner probe. Doing so allows you to acquire reference scans before introducing the sample.

Acquire data via the sample list with the Tune window open (refer to the MassLynx online Help for detailed instructions). Also create a method suitable for your instrument. See page 2-12 for examples of method parameters for each compatible instrument.

Once you insert the inner probe, increase the desolvation temperature to vaporize the sample. During an acquisition, you can manually change the temperature. When you complete the acquisition, the desolvation temperature returns to the value set in the Tune window.

Tip: For the LCT Premier XE, with lock spray enabled, when you withdraw the inner probe during the acquisition, the desolvation temperature returns to the start value set in the Tune window. Using this technique, you can save multiple analyses to a single data file.

As the instrument operates in ESCi mode, sample data are acquired in APCI mode, and lock-spray reference data (for lock-mass correction) are acquired in ESI mode. Both data types appear in the Tune window.

Ionization mechanisms

In the ASAP technique, ion generation in positive-ion mode comes about by corona discharge, forming both radical cations (M+•) and protonated cations (M+H)+. Source conditions greatly affect the ions' state. A dry source—one that underwent overnight baking and to which no lock reference is introduced—favors the formation of radical cations. A source that is not dry favors the formation of protonated cations because it contains water vapor or deliberately introduced reference solution. The presence of water or other solvents in the source can severely affect the sensitivity of many nonpolar species, which tend to form radical cations.

The following examples illustrate the different ionization mechanisms, using progesterone as the sample.

Ionization by charge transfer:

This example uses a background ion for lock mass correction. The principal ion generated is the radical cation at m/z 314, but evidence of the protonated molecular ion also exists. The peak at m/z 315 is bigger than expected for the carbon 13C isotope alone because of traces of water vapor in the source.

Calculated mass for radical cationM+• = 314.2241

Analyzing samples 2-7

Page 26: Atmospheric Solids Analysis Probe - Waters Corporation · 2012-01-10 · Inserting the inner probe Refer to the figure on page 1-8 while following this procedure. If you are using

Ionization by proton transfer:

In this example, the protonated molecule appears as the major species, with little evidence of radical cations. The same sample and source conditions used in the previous example were used in this one, except that a lock reference solution was introduced, at 2 µL/min. Note that the degree of protonation also depends on the proton affinity of the analyte molecule. High proton affinity favors the formation of the protonated molecule.

Analyzing non-polar compounds

The ASAP technique particularly suits analyzing nonpolar compounds. See the figures on page 2-9, which show the results obtained from hexachlorobenzene (C6Cl6), which is normally done using the EI/CI technique under vacuum conditions.

In the following examples, the sample is introduced directly into the source. Because of the source chamber’s dry nitrogen atmosphere, radical cations form rather than the protonated ones (see page 2-7).

Calculated mass for protonated molecule(M+H)+ = 315.2324

Predicted and actual spectra (hexachlorobenzene):

The example shows the predicted isotope model for hexachlorobenzene as compared with the actual spectrum acquired using the ASAP technique. Comparison of the two spectra shows that they are a very close match, indicating the usefulness of the ASAP in analyzing compounds that normally require analysis with a vacuum solids probe technique.

Page 28: Atmospheric Solids Analysis Probe - Waters Corporation · 2012-01-10 · Inserting the inner probe Refer to the figure on page 1-8 while following this procedure. If you are using

Thermal fragmentation

Controlling the temperature of the desolvation gas when analyzing samples significantly changes the appearance of the resulting spectrum because thermal fragmentation occurs at higher temperatures. The following example illustrates this effect using the hydrocarbon tetracontane (C40H82) as the sample.

Thermal fragmentation (tetracontane):

In this example, the lower spectrum shows the formation of the radical cation at m/z 562.6 when the temperature reaches 100 ºC. The upper spectrum acquired at a temperature of 250 ºC clearly shows that thermal fragmentation occurred.

Temperature = 250 ºC

Temperature = 100 ºC

Using modifiers

You can use to your advantage the tendency to form either protonated or solvated cations during an ASAP analysis. The following example shows how an analysis of Krytox® (a perfluorinated synthetic lubricant) produces different spectra under dry conditions versus the separate addition of methanol and ammonium hydroxide. Adding the modifiers generates solvent adduct ions (M+CH3OH+H)+ or (M+NH4)

+ of the polymer species, which simplifies the spectrum and aids in determining molecular weight.

Analysis of Krytox using modifiers:

Recommendation: You can introduce modifiers into the source by placing an unstoppered vial of the modifier inside the source chamber or infusing the modifier directly via the LockSpray interface.
