Application Notes: GC-MS

Automated GC/MS determination of 3-MCPD and glycidol in edible oils. Evaporation step helps reach required LODs with standard MSD and removes excess derivatization reagent for improved stability.

Automated QuEChERS clean-up of hemp oil extracts combined with liquid introduction and PTV-GC–MS determination of pesticides leads to improved throughput and low LOQs.

-GC×GC offers dramatic improvements over traditional gas chromatography for the analysis of complex mixtures in numerous applications -The power and utility of GC×GC technology -The need for more advanced and novel stationary phases for gas-chromatographic columns

• Robust and sensitive sampling, using HiSorb™ high-capacity sorptive extraction probes with preconcentration on the Centri® platform. • Enhanced confidence in identification, through use of the Tandem Ionisation® providing hard & soft EI spectra in a single run. • Highly sensitive SCD screening for odour taints caused by trace sulfur species.

This application demonstrated a fragrance profiling study by a CDS Analytical 7000C concentrator with a dynamic headspace module on a PAL RTC rail. The results were compared to direct GC injection.
