    CTR Columns

    CTR Columns For Gas Analysis CTR Columns Permit the Simultaneous Use of Two Different

    Packings for Your Analysis

    CRT I is Ideal for Separating O2, N2, CH4, CO, CO2 at AmbientConditions

    CRT III is Ideal for Argon Analysis in the Presence of O2

    Useful Where Two Separate Chromatographic Runs are Requiredto Analyze One Sample

    Individually Tested

    CTR is Alltechs designation for a series of concentric columnswhich offer many advantages for certain types of difficultanalyses. A CTR column is essentially a column within a column.This permits you to use two different packings for the analysis ofyour sample. The diagram below shows the construction of theCTR column.

    CTR I - Oxygen, Nitrogen, Methane, CarbonMonoxide and Carbon Dioxide

    Until the CTR, no single column operating at room temperaturehas been designed to permit, in one analysis, the separation ofoxygen, nitrogen, methane, carbon monoxide and carbon dioxide.Usually this analysis is accomplished by either making twoseparate runs on the sample of interest or employing a switchingvalve and polarity change during the analysis. The reason for thisdifficulty is that carbon dioxide is irreversibly absorbed on themolecular sieve which must be used to obtain the oxygen/nitrogen split. In addition, porous polymers and silica gel, whichare widely used to separate carbon dioxide from otherconstituents, do not separate carbon monoxide from thecomposite air peak at room temperature.

    With Alltechs CTR columns, this type of analysis can beroutinely handled in a one-step operation. The developmentpermits you to analyze oxygen, nitrogen, methane, carbonmonoxide and carbon dioxide under isothermal conditions, atroom temperature, and in less than 10 minutes. A quick method!
