Split vs. Splitless: Which GC Injection Mode Should I Use?
Split and splitless are the two most common GC injection techniques. But how do you know which to use? In this video, we follow a sample through split and splitless injections and compare the strengths of each technique to help you choose the right one for your analysis.
Discovering Analyte Breakdown On-Column: Nitrosamines on Cyano Columns
What might a small foot on the leading edge of a GC peak indicate? In this series of experiments with nitrosamines, intern Yannic Schneck demonstrates how on-column breakdown occurs in correlation with elution temperature on several cyano-based stationary phases.
Model Azo Dye Aryl Amines with Pro EZGC: New Libraries Now Available!
Azo dyes are used in foods, textiles, paints, and many other products, but some form carcinogenic aryl amines that pose human health risks. The Rxi-35Sil MS column has proven to be an excellent solution for the analysis of 24 aryl amines, and we have updated our Pro EZGC libraries to allow modeling of these compounds and others.
Drop ASTM D7504 Solvent Analysis Time from 23 Min to 8 Min
ASTM D7504 is used for analyzing trace impurities in monocyclic aromatic solvents by GC, but the run time on a 60 m column is very long (23 min). In our alternative approach, a 20 m Stabilwax column meets method requirements and provides equivalent purity results in just 8 min.
