App Notes

Dual-detection Gel Permeation Chromatography (GPC), also known as Size Exclusion Chromatography (SEC), provides an easy and effective way to measure the molar mass distribution and the amount of free, unbound polysaccharide of iron polysaccharide complexes.

This 28-page e-book from Markes International describes how thermal desorption (TD) with gas chromatography (GC) can be used to tackle key applications in the field of fragrance and odour profiling.

This 44-page e-book from Markes International describes how thermal desorption (TD) and related sampling techniques can be interfaced with gas chromatography (GC) for the analysis of volatile and semi-volatile organic compounds (VOCs and SVOCs) in a wide variety of foods and drinks.

This 36-page e-book from Markes International describes the role of thermal desorption (TD) for assess volatile and semi-volatile organic compounds (VOCs and SVOCs) in ambient air, whether outdoors or within buildings.

The first section of this 29-page e-book from Markes International describes how thermal desorption (TD) can be applied to the detection of chemical agents in military applications, including on-line monitoring for rapid incident response, and off-line tube-based analysis of stockpiles.

This information-packed 32-page e-book from Markes International describes how thermal desorption (TD) and related sampling techniques can be used to rapidly produce meaningful information on emissions of volatile and semi-volatile organic compounds (VOCs and SVOCs) from a variety of materials.

This 27-page e-book from Markes International describes how thermal desorption (TD) is being applied to advanced research in three areas relating to emissions of volatile and semi-volatile organic compounds (VOCs and SVOCs) from living organisms – disease diagnosis using breath volatiles, the role of biogenic VOCs in the atmosphere, and studies into chemical ecology.

This 27-page e-book from Markes International describes the role of thermal desorption (TD) and related sampling techniques within the standard analytical methods used in the automotive industry to assess volatile and semi-volatile organic compounds (VOCs and SVOCs) emitted from car trim.

LMWHs are defined as heparin salts having an average molecular weight of less than 8000 Da. Both, the Pharmaeuropa and the US Pharmacopeia, require GPC/SEC to characterize e.g. Enoxaparin Sodium or other low molar mass heparins with respect to molecular weight. A dedicated GPC/SEC software such as PSS WinGPC UniChrom is required to obtain reliable mass fraction information.

In a collaborative study with Novartis Institutes for Biomedical Research, a thermal unfolding assay using nanoDSF is applied to understanding the stabilizing effects of ligands on G protein-coupled receptors. See how nanoDSF provides an easy solution for this difficult target.
