Analysis of Polychlorinated Biphenyls in Fish Oil Using Supelclean™ EZ-POP NP, Silica Gel SPE, and an SLB®-5ms GC Column
Polychlorinated biphenyls (PCBs) were once widely used in many industrial and commercial applications such as insulating fluids, dielectrics, and lubricants. This included their extensive use in electrical transformers. PCB use has been banned in many countries, and the Stockholm Convention
Food & Beverage Analysis: Sugars & Saccharides
Simple sugars using hydrophilic interaction chromatography (HILIC): Chromatographic analysis of simple sugars can be challenging because these compounds are highly polar, uncharged, and lack a chromophore. The preferred mode of HPLC separation is HILIC because it provides the advantage of
Measuring Peroxidase in Milk
Application Note: Peroxidase in milk – Visual determination after conversion of a specific substrate
Analysis of Vitamin D in Milk and Infant Formula using UHPLC/MS/MS per AOAC Method 2011.11
While quantitative analysis was performed for Vitamins D2 and D3, the samples were scanned for the presence of the 25-hydroxy metabolites.
Analytical Method: Determination of the Solution Color of Raw Sugars, Brown Sugars and Colored Syrups at pH 7.0 (According to ICUMSA Method GS1/3-7)
Method: Spectrophotometric Color Determination at 420 nm Zero adjustment For each measurement series, a zero adjustment is required. It is recommended to use the same cell for zero adjustment and for sample measurement. The zeroing procedure for the measurement series is automatically prompted by
