Nov 14, 2016 · Many chemical compounds, including drugs and metabolites, can be analyzed by either gas chromatography (GC) or high-performance liquid chromatography (HPLC). Because both techniques function under the same basic principles of compound separation, identification, and quantification, it can sometimes be tricky to choose one over the other. But knowing what differentiates HPLC and GC can

7.4.2. Flame Thermionic Detectors (FTD) The FTD is a selective, high-sensitivity detector for organic nitrogen compounds and inorganic and organic phosphorus compounds. (The selectivity of the FTD for phosphorus compounds is not as good as the FPD.) The FTD does not react to inorganic nitrogen compounds.

The system can handle standard headspace apps (that require temperatures lower than 150°C) while still being well-suited to special high-temperature apps that include analysis of high-boiling compounds and polymers. HT2000HT is the perfect instrument for quality control of chemical product materials and for heat-induced degradation studies.

Gas Chromatography. Gas Chromatography (GC) is a technique for separating and analyzing compounds that can be vaporized without decomposition, and is widely used in environmental testing and forensic science, as well as for Pharma R&D and QC applications.

Apr 20, 2021 · Gas Chromatography, Second Edition, offers a single source of authoritative information on all aspects relating to the practice of gas chromatography. A focus on short, topic-focused chapters facilitates the identification of information that will be of immediate interest for familiar or emerging uses of gas chromatography.

Jan 01, 2020 · Gas chromatography vs. liquid chromatography. High performance liquid chromatography (HPLC) is well suited to ICPOES or ICPMS interfacing because the flow rates of the HPLC system and nebulization rates in the ICP are comparable (see Chapter 4). In many cases HPLC as an introduction system negates the need for derivatization.
