This page shows how to perform a separation with a Sephadex LH-20 column from Cytiva which are Size Exclusion Chromatography media of polysaccharide network made from cross-linked hydroxypropylated dextran beads.
Static headspace GC (GC-SH) is a technique used to concentrate volatile analytes prior to analysis. It can improve detection of low level volatile analytes and minimizes matrix interference by eliminating the need to inject the sample directly.
The Amberlite™ XAD-4 resin used in Porozorb™ cartridges is a proven technology that is highly effective in removing various detergents from cell culture media for biopharmaceutical applications such as vaccine production.
The recent addition of Alumina sulfate and Alumina chloride columns to the Supelco family of GC capillary PLOT columns has prompted several customer inquiries on why we offer two alumina chemistries and how to chose between the two. We present
GC Analysis of Xylene Isomers on SLB®-IL60 - The cresol (methylphenol) isomers are also precursors to many chemicals. This chromatogram of a mix of aromatic and methylphenol compounds was generated using an SLB-IL60 ionic liquid column. Its interaction mechanisms allow
Fast GC analysis is typically performed using short, 0.10 mm I.D. capillary columns with H2 carrier gas and rapid temperature programming rates. FAMEs can be analyzed with a variety of 0.10 mm I.D. columns, depending upon the information required.
