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.

AN329: Determination of Total Fat in Powdered Infant Formula Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

The U.S. Nutritional Labeling and Education Act of 1990 requires that food products carry labels listing the content of saturated and unsaturated fats. Accurate determination of fat in certain foods is difficult due to the binding or entrapment of the fat by the matrix. Accelerated Solvent Extraction (ASE) is a new automated extraction technique that can significantly reduce extraction time and solvent consumption and yields equivalent results, without requiring a pretreatment step. In this application note, fat is extracted from infant formulas by ASE without aggressive pretreatments.

Increasing Productivity in FAMEs Analysis through Increased Selectivity

Instrument Type: GCMSMS

In this work, the performance of the Thermo Scientific TSQ Duo system is assessed for the quantitative analysis of 11 FAMEs in human blood spot extracts. The TSQ Duo system offers analysts a unique choice by allowing the use of single quadrupole methods and enabling the automatic transition to triple quadrupole on the same system. This application note illustrates the stepwise process of upgrading methods from single quadrupole to triple quadrupole using Chromeleon CDS software.

Separation of fatty acid methyl esters using a high-polarity, phase-optimised GC column and a GC/FID detection technique

Instrument Type: GC

The Thermo Scientific TRACE GC Ultra is applied for the analysis of fatty acid methyl esters (FAMEs). The separation was performed on a Thermo Scientific TRACE TR-FAME GC column, with flame ionisation detection.

Fast analysis of FAMEs by GC-FID

Instrument Type: GC

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.
