Method Translation for PLOT Columns: Switching Carrier Gases Using EZGC Software
The EZGC method translator is an essential tool for modifying methods on gas-liquid GC columns, but will it also work for adsorption-based PLOT columns? We used it to change carrier gases for the analysis of hydrocarbon contaminants in propylene on an alumina column and here’s what we found…
Check These 10 Common GC Leak Locations Today
Even the smallest gas leak can cause a loss in sensitivity, contaminate samples, damage columns and instruments, and lead to a lot of wasted time. Grab your leak detector and check these 10 common leak locations now to keep your GC running smoothly.
A Selectivity Map for Noble and Permanent Gases on Adsorbent Columns
Predicting adsorbent column selectivity is often a wild guess. Argon will have less retention than krypton, but how well will noble and permanent gases be separated? To give definite answers, we mapped out column selectivity for noble gases relative to permanent gases.
How do I choose the right dip tube for my sampling cylinder?
A dip tube (outage tube) provides vapor space above liquefied gases in a sampling cylinder so that pressure will not significantly increase if expansion occurs at higher temperatures. Here’s how to select the right length and material to ensure proper performance.
