Abstract: The ability to identify volatile and semi-volatile contaminants present in food products without the use of solvent extractions has several advantages including improving sample throughput, reducing the chance of a volatile component being “lost” in the extraction process and eliminating the need for solvent disposal. This study utilizes the advantages of direct thermal extraction GC/MS to identify contaminants in powdered food products. Direct Thermal Extraction GC/MS provides for fast analysis with no carryover problems that can be associated with other GC/MS techniques.Summary: Direct thermal extraction GC/MS is a quick way to identify contaminants in food products without the use of solvents. Each sample has its own unique transfer line and this eliminates the problem of carry over or cross contamination that is frequently encountered in other GC/MS techniques.References: 1. David F.
