A new C-IC total workflow system has been introduced: the Thermo Scientific™ Cindion™ Combustion/Absorption Module, and an autosampler that can be configured for solid or liquid samples. A standalone Thermo Scientific™ Cindion™ LPG/gas Module is also an option. In this technical note, we describe the configuration and operation of the Cindion C-IC system with the following configurations: Cindion combustion/absorption Module with Cindion autosampler: 1. Solids sampler and with the offline Cindion adsorption module needed for U.S. EPA Method 1621. 2) Solids sampler, 3.Liquids sampler.
A time and labor-saving online sample preparation workflow by amino acid derivatization in the autosampler's needle is presented for medium and highly complex sample matrices (beverages, food, and fertilizers) analyzed at one external and two in-house laboratories. Robust and reproducible method performance, column stability over several hundred injections, and applicability at different instrument tiers are highlighted.
HPAE-PAD is a well-established technique for separating and quantifying a wide range of carbohydrates, providing high resolution separation and high sensitivity. This document discusses the basics of the separation and detection mechanisms and limitations of HPAE-PAD, good practices and techniques for successful analyses.
The proper preparation and use of eluents are the most crucial parts for success in carbohydrate analysis with ion chromatography with PAD detection. This document describes purity criteria for reagents, proper eluent storage, proper use, identification of contaminated eluent and consequences.
To demonstrate the suitability of the Thermo Scientific™ TSQ™ 9610 triple quadrupole GC-MS/MS system with Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS) software for the routine and regulatory compliance testing of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (PCDD/Fs) in food and feed. Analysis of food and feed samples previously analyzed by the European Reference Laboratory for POPs (Freiburg, Germany) and the Wageningen Food Safety Research laboratory (Wageningen, Netherlands) was carried out to ensure results were consistent.
