Aug 9, 2019 · This application shows a method for HPLC-CAD analysis of polyethylene glycol (PEG). PEG is a polyether compound – a polymer of ethylene glycol. A number of PEGs exist …

Size exclusion chromatography (SEC) is often applied to characterize protein–polyethylene glycol (PEG) conjugates and establish the number of attached PEG chains, since SEC is a precise …

Mar 27, 1998 · Mixtures of PEGs have been determined by these HPLC systems. PEG 400 in a textile finish has also been determined with satisfactory recovery. It has been found that the …

Aug 16, 1991 · HPLC analysis of PEG with an average molecular weight of 2000 dalton, spiked with a probe compound mixture: 1 = benzamide; 2 = phenol; 3 = p-cresol and 4 = anisole. The …

Sep 1, 1994 · We describe a simple HPLC technique to determine the oligomeric profile of PEG excreted in urine. We measured the total (%) PEG excreted in 6 h and the ratio of the four …

High performance liquid chromatography, namely HPLC, is a well-known and efficient separation and analysis technology for free PEG and its PEGylated conjugate. Moreover, HPLC is also a …

Jun 1, 2012 · While the PEGylated protein products can be characterized by HPLC with UV or MS detection, it is difficult to quantify the PEG and PEGylation reagents because they lack a …

This protocol describes a method for the quantitation of polyethylene glycol (PEG) in PEGylated colloidal gold nanoparticles using reversed phase high performance liquid chromatography …
