The Thermo Scientific TRACE GC Ultra is applied for the comparison of a fused silica and a metal GC column using a standard test mix. The columns compared are the Thermo Scientific TraceGOLD TG-WaxMS and TraceGOLD TG-WaxMT GC columns and full method details are available in the application note PDF.

The Thermo Scientific TRACE GC Ultra is applied for the analysis of vanillin from a cola soft drink. The sample was prepared using Thermo Scientific SOLA HRP solid phase extraction (SPE) cartridges, and the separation was performed on a Thermo Scientific TraceGOLD TG-WaxMS A GC column, with flame ionization detection.

In this work, the performance of a 0.15 mm internal diameter (ID) GC column is compared with that of a 0.25 mm ID GC column. A 50% increase in the speed of analysis for a 14 component fatty acid methyl ester (FAME) reference standard C8–C24 mix is demonstrated using the 0.15 mm GC column. No compromise in the separation capability of the method was observed, and conversion of the conventional method was easily achieved using conventional GC instrumentation.

An extraction of acrylamide from potato chips was performed using Thermo Scientific HyperSep Hypercarb solid phase extraction (SPE) with quantitation of acrylamide performed using a Thermo Scientific GC-MS with a Thermo Scientific TraceGOLD TG-WaxMS GC column. A standard addition calibration curve was used to estimate the level of acrylamide in potato chips and found to be 450 µg/kg.

The Thermo Scientific GC system is applied for the analysis of diethylene glycol and ethylene glycol in toothpaste. The separation is performed using a Thermo Scientific TraceGOLD TG-WaxMS column with 5m SafeGuard.
