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.

AN362: Extraction of Herbal Marker Compounds Using Accelerated Solvent Extraction Compared to Traditional Pharmacopoeia Protocols

Instrument Type: Automated Sample Prep

The Accelerated Solvent Extraction system (ASE) uses elevated temperature and pressure to increase the efficiency of the extraction process. ASE automates and improves solvent extraction by significantly decreasing solvent consumption and extraction time. This application note describes the use of the ASE system for solvent extraction of five marker compounds from herbal preparations followed by analysis by HPLC. The results are compared to traditional pharmacopoeia extraction methods.

AN352: Rapid Determination of Persistent Organic Pollutants (POPs) Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

The following compounds are listed by UNEP to be POPS: • Pesticides: Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, and Toxaphene • Industrial chemicals: Hexachlorobenzene, and PCB (polychlorinated biphenyl) • Chemical by-products (Dioxins): Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD and PCDF) This application note describes methods and results for extraction of the POPs listed above, with tables comparing ASE to traditional extraction methods.

AN346: Totally Automated Sample Preparation Using Accelerated Solvent Extraction (ASE) Coupled with Gilson ASPEC: The Determination of Dianthrones in St. John's Wort

Instrument Type: Automated Sample Prep

This Application Note reports on the use of a coupled ASE-ASPEC system as an automated extraction and extract manipulation device for the determination of dianthrones in St. John’s Wort (Hypericum perforatum). The results using the coupled system are compared to those obtained using a traditional sonication procedure followed by manual SPE cleanup.

AN340: Determination of Fat in Dried Milk Products Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

This Application Note describes the extraction of fat from a variety of dried milk products. The samples range from very low-fat products such as skim milk powder to very high-fat products such as cream powder. The extraction of fat from these matrices is rapid and the results are equivalent to the referenced traditional methods.
