App Notes

The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air.

This Application Note looks at the photometric determination of manganese sulfate using the Optrode (610 nm). Manganese is titrated with EDTA; Eriochrome Black T is used as indicator.

The development of electrospray tandem mass spectrometry (LCMS/MS) in recent years has facilitated the introduction of expanded newborn screening programmes

The objective of the study presented here is to develop a suite of toxicity markers from GC-TOFMS analysis, for use in pre-clinical screening of drug candidates.

Vulcanized rubbers are particularly difficult materials to analyze because of the opacity and insolubility of the rubber.

Size Exclusion Chromatography (SEC) separates analytes by their molecular weight (MW) and/or the hydrodynamic radius (size, shape of the molecule).

Aflatoxins are mycotoxins, structurally related compounds produced as secondary metabolites by Aspergillus molds, primarily flavus and parasiticus.

Monoclonal antibodies (mAB) are increasingly growing in importance for the diagnosis and therapy of various diseases, including cancer as well as autoimmune and inflammatory disorders.

Extraction of lipids as fatty acids and the subsequent detection of trans fats from a cookie sample, using Silver-Ion SPE fractionation followed by GC analysis on SP-2560 and SLB-IL111 columns
