The aim of this study is to demonstrate the suitability the Thermo Scientific™ TriPlus™ RSH SMART robotic sampler handler autosampler coupled to the Thermo Scientific™ TRACE™ 1610 GC series for automated sample preparation and on-line analysis of biodiesel according to the EN 14105 and ASTM D6584 methods.
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.
Two oral, over-the-counter medications were evaluated as representative pharmaceutical products. A cough suppressant and a multisymptom cold/flu medication were chosen because they contain a complex mixture of simple sugars, glycols,and sugar alcohols. These carbohydrates and glycols are also commonly found in other medications. This method uses the CarboPac MA1 column to retain and separate the target analytes.
This application note describes the use of three different anion-exchange columns with amperometric detection to analyze common simple sugars, sugar alcohols, and glycols in pharmaceutical formulations. This record describes a method using the CarboPac PA10 column to determine some of the target carbohydrates. The reader is advised to review TN21 for updated waveform information.
