Pesticides: From analytical standards to certified reference materials
This webinar will describe a routine certification procedure using the example of pesticide standards from the point of view of a commercial producer of CRMs and will include specific selection criteria, pre-tests, experimental conditions, homogeneity and stability studies.
Identification of Decaffeinated Green Tea Dry Extract according to USP DSC 2018
Powdered Decaffeinated Green Tea Extract is prepared from the young, unfermented leaf and leaf buds of Camellia sinensis (L.) Kuntze (Fam. Theaceae), also known as Thea sinensis L. This HPTLC method identifies Powdered Decaffeinated Green Tea Extract as defined by USP DSC 2018.
High Sensitivity Multi-steroid Panel Assay using Supported Liquid Extraction
A wide range of steroids are included in this application note and many other neutral endogenous steroids can be extracted using similar conditions. This high sensitivity method includes optimised UHPLC separation and MS-MS ionisation conditions, and advice on modification for inclusion of DHEAS in the panel.
Simple, Rapid Detection of Edible Oil Oxidation Using Direct MS
Process-line or laboratory detection of edible oil oxidation is achieved extremely simply by applying selected ion flow tube mass spectrometry (SIFT-MS). Direct headspace analysis of fish oil using SIFT-MS enables instantaneous quantification of volatile oxidation markers.
Polymer Nanoparticle Characterization Using Dynamic Light Scattering
Here we discuss the influence of temperature on the size of polymer nanoparticles using dynamic light scattering. In the example, an increase in temperature has resulted in the swelling of polymer nanoparticles causing an increase in their size and a decrease in the scattering intensity.

42nd International Symposium On Capillary Chromatography and the 15th GCxGC Symposium
The ISCC and the 14th GC×GC Symposium is a “hyphenated” meeting, which will be held at Riva del Garda, Italy, sponsored by Chromaleont S.r.l.
Apart from the most recent advances in the fields of pressure and electrodriven microcolumn separations techniques, and comprehensive 2D GC, this year particular emphasis will be directed to all combinations of Comprehensive Separation Technologies and Capillary Chromatography with various forms of MS.
