A breakthrough for adsorbable and extractable organic fluorine (AOF and EOF) and how different SPE phases are used for accurate determination of PFAS.

Adsorbable organically bound fluorine (AOF) is used to screen water for PFASs. DIN 38409-59 outlines AOF analysis with pyrohydrolytic combustion and ion chromatography.

HDX-MS with online EC reduction enables successful epitope mapping of mAbs to challenging S-S bonded protein targets, e.g., VEGF. The biophysical characterization of VHH-IR4, a BBB-crossing single-domain antibody (sdAb) is described for the first time and was only possible using EC reduction.

High-Performance Anion Exchange Chromatography in combination with PAD or MS detection is the method of choice for the analysis of all classes of carbohydrates including glycans. A novel anion-exchange stationary phase SweetSep™ has been developed that allows for fast and high resolution separation.

The new column enables for (a) fast, high-resolution separation of carbohydrates, (b) analysis of carbohydrates over a high molecular weight range: from mono– to oligosaccharides, (c) analysis of complex carbohydrate mixtures in food (e.g., honey, lactose in lactose-free labeled products, fructooligosaccharides, etc.).

Shodex collaborated with Claros Technologies using HILICpakTM VT-50 2D Shodex column to study PFAS in industrial and ground water samples. Per and polyfluoroalkyl substances (PFAS) have been in industrial use since the 1960’s and are commonly found in the environment.

Different classes of antibodies, including IgG1, 2 and 4, are immediately reduced down to light and heavy chain without the need of enzymes, denaturing or reducing agents using inline EC-LCMS. The workflow can be used for IdeS digested mAbs and does not affect the quantitation of acid labile species such as sialylated N-glycans.

Process and Quantitate All xC/UV/MS Data in a Single Interface with Software Compatible with Major Vendor Formats.

The AEX200 column demonstrate (a) fast separation of mono-, di- and trisaccharides in various food sample matrices, (b)sensitive quantification of carbohydrates down to femtomole levels, (c) high-resolution separation of high-molecular weight oligosaccharides with a degree of polymerization up DP of 60.

Separation of all 6 glycan monosaccharides of interest and 2-Deoxy-D-Glucose (glycosylation inhibitor) was achieved within 7 minutes using the new SweetSep™ AEX20 column under isocratic elution conditions. Furthermore, profiling of released N-glycans from glycoproteins without the need for sample derivatization is shown using HPAEC-MS.
