AN361: Extraction of Total Fat from Food Samples After Acid Hydrolysis Using Accelerated Solvent Extraction with GC-MS Analysis

Instrument Type: Automated Sample Prep

Complex matrices such as food typically require acid hydrolysis or pretreatment prior to solvent extraction. Our newly updated flow-through solvent extraction system allows extraction of matrices which require acidic or alkaline pretreatment. The ability to extract these pretreated matrices significantly expands the capabilities of accelerated solvent extraction technology.This Application Note describes methods used for extraction of total fat from food samples and determination of fat content by FAME (Fatty Acid Methyl Ester) analysis based on AOAC Official Method 996.06 section G.

Identification of Cannabinoids in Baked Goods by UHPLC/MS

Instrument Type: LCMS

Marijuana is the most common illegal drug in the United States. Presumptive positive results are confirmed by using GC/MS to positively identify cannabinoids. While this traditional approach works fairly well for leaf marijuana, hashish, hash oil and residue collected from smoking paraphernalia, GC/MS is less useful for confirming the presence of marijuana in complex food matrices such as baked goods. We describe a method to positively identify trace amounts of cannabinoids in a complex food matrix quickly, with minimal sample preparation and no chemical derivatization.
