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.
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination
Terpenes are present in essential oils derived from plants and often impart characteristic aromas to the plant or its oil. The SPME is a convenient, efficient, and easy to automate sample preparation technology for analyzing the terpene/terpenoid profile of these
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.
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
A step-by-step description of the reflectometric determination of sucrose (saccharose) in soft drinks using Reflectoquant® test strips and reflectometer, ideal for in-process control and on-site testing.
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
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
