METHODS LIST
Methods List forAutomated Ion AnalyzersFlow Injection Analysis • Ion Chromatography
SEPTEMBER 2013
QuikChem® Methods List Use this list to:
• Identify and select analytical methods for your analyte, range, and matrix requirements. • Locate all current Lachat methods for ion chromatography and flow injection analysis. • Find methods accepted for USEPA compliance monitoring. These methods have symbols after
the method number depending on whether the method is Accepted or Equivalent for NPDES and/or NPDWR reporting. Additional regulatory information can be found in the Regulatory Quick Reference section.
• Find methods with ERA or other external QC included in the support data. These methods have a * after the method number.
Performance Data Specifications • Range: The range quoted in the Lachat methods list is based on the actual, calibrated range. The
calibrated range is the lowest calibration standard to the highest calibration standard. (A blank is typically included in the calibration, but is not included in the method range.)
. • MDL: The MDL (method detection limit) is calculated by the following protocols:
The Student’s T number for the number of replicates is multiplied by the standard deviation calculated from those replications.
If 7 replicates are used: The Student’s T value is 3.14.
If 21 replicates are used: The Student’s T value is 2.528.
Example for 21 replicates: 2.528 X 0.123 = 0.39 for an MDL
• Quantitation Limit: Quantitation limit is typically 3 to 5 times the calculated MDL or 10X the standard deviation of the MDL standard used. Typically, this is the lowest calibration standard in a given method.
• Precision: Stated in the methods as %RSD. %RSD is calculated as follows: %RSD = (SD /Mean) x 100
Part Numbers Versus Method Numbers To convert Method Numbers to part numbers, place an E in front of the Method Number.

The analytical capabilities of these instruments are not
limited to these methods. The Lachat Applications group regularly adds new methods to this list. Requests for custom and proprietary methods development or consulting can be sent to Lachat Sales at 800-247-7613 ext 3580 or [email protected]. •Methods, other than those listed as EPA-Accepted, were developed to meet individual customer requirements. In order to ensure that Lachat
methods exactly meet the requirements of your application, please contact your local Sales Representative or Distributor •When you have purchased a manifold, a copy of the method will be sent with a manifold diagram. Copies of methods without manifold diagrams are
available to Lachat customers upon request.
