High Temperature Stability Problem Solved with New Metal Columns - Analysis of Total Glycerides in Biodiesel Oils by ASTM D-6584
Jun 06 2007
Author: Barry L. Burger and Jaap de Zeeuw on behalf of Restek Corp
One of the biggest challenges in biodiesel fuel analysis is the accurate determination of residual triglyceride content. Triglycerides are present at low levels and elute at high chromatographic temperatures. Any suitable column must be operated at temperatures up to 380°C, which considerably strains conventional capillary tubing and stationary phases. Restek has developed new 0.32mm ID and 0.53mm ID MXT® stainless steel capillary columns—the MXT®-Biodiesel TG line—specifically for high temperature biodiesel analysis. Here we demonstrate the analytical advantages of full metal columns: unsurpassed stability at high temperatures, excellent peak symmetry for triglycerides, highly reproducible retention times, and unsurpassed column lifetimes.
