The aim of this study is to demonstrate the suitability of the Thermo Scientific™ TriPlus™ 500 static headspace autosampler in combination to the Thermo Scientific™ TRACE™ 1610 GC to run an optimized rapid method for the determination of Class 3 residual solvents in pharmaceutical products
The aim of this application note is to demonstrate the suitability of the Thermo Scientific™ TRACE™ 1310 Gas Chromatograph coupled with flame ionization detection (FID) for the determination of ethanol (in compliance to the USP <611> method) and isopropanol content in hand sanitizers.
Using an analytical system comprised of Markes CIA Advantage-xr canister autosampler, Kori-xr water removal device, and UNITY-xr thermal desorber coupled to a dual-column Thermo Scientific™ ISQ™ 7000 single quadrupole GC-MS, for the analysis of ozone precursors, air toxics and oxygenated volatile organic compounds in ambient air.
This Application Note describes the use of two different anion-exchange columns with amperometric detection to analyze simple sugars, sugar alcohols, alcohols, and glycols in yeast and bacterial fermentation broths. This record describes the CarboPac MA1 column method. The yeast Saccharomyces cerevisiae in Yeast Extract-Peptone-Dextrose (YPD) broth and the bacteria Escherichia coli (E. coli) in Luria-Bertani (LB) broth are common eukaryotic and prokaryotic fermentation systems, respectively.
This application note describes the use of ion-exchange or ion-exclusion chromatography for the determination of five classes of compounds of interest to the brewing industry, including: carbohydrates, alcohols, organic acids, inorganic anions, and inorganic cations. One of two forms of electrochemical detection is used, pulsed amperometry or conductivity detection. This part of the application note describes the alcohol analysis which uses pulsed amperometric detection. This was formerly Dionex AN46.
