The Elite-624 column is a specially engineered, low to mid-polarity (6%-cyanopropylphenyl)-dimethylpolysiloxane phase. The unique polarity of this phase makes it ideal for analyzing volatile organic pollutants and it is recommended in U.S. EPA methods. The Elite-624 phase produces greater than 90% resolution of the first six gases in EPA Methods 8260 and 524.2. This stationary phase is especially well-suited for EPA Method 524.2 since it resolves 2-nitropropane from 1,1-dichloropropanone, which share quantification ion m/z 43 and must be separated chromatographically.

During gas chromatography (GC) column installation, ferrules are used to provide a leak-free seal. Different materials and configurations of ferrules are available, the choice of which depends on your application and use within the GC instrument. This primer provides a guide to GC column ferrule sel ...
Choosing which chromatography column to install is perhaps the most impactful decision a chromatographer routinely makes. Since the separation of compounds by GC is governed by a molecule’s partitioning properties between the carrier gas and the column’s stationary phase, the careful selection of wh ...
A gas chromatography (GC) column the vital key to any GC separation, and selecting the correct key is crucial to helping you unlock the information found inside your sample. PerkinElmer is proud to offer a comprehensive selection of GC columns spanning a wide selectivity range with many different co ...
