Enzymatic methods for food analysis are highly specific and offer considerable time and cost savings over other methods, especially from the sample preparation standpoint. We offer a wide variety of convenient kits and reagents for rapid and reliable enzymatic food
This assay protocol is suitable for the colorimetric/fluorometric detection of Galactose and Lactose in cell and tissue culture supernatants, urine, plasma, serum, and other biological samples using the Galactose and Lactose Assay Kit (MAK011). In this assay kit, galactose is
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
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
Method: Spectrophotometric Color Determination at 420 nm
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
The use of solid phase microextraction (SPME) allowed for the straightforward, fast, sensitive, and accurate GC/MS determination of the residual solvent content of spiked and unspiked samples of hemp extract.
This assay protocol is suitable for the colorimetric/fluorometric detection of Galactose and Lactose in cell and tissue culture supernatants, urine, plasma, serum, and other biological samples using the Galactose Assay Kit.
RP-Amide and HILIC, both amenable to the analysis of polar compounds, were successfully used to resolve several beverage components, including sugars, vitamins, sweeteners, preservatives, and caffeine.
