High Performance Liquid Chromatography (HPLC) Method for Analysis of Ethylene glycol, PEG 200, PEG 400.
Polyethylene glycol (PEG) has a low toxicity and is used in a variety of products (creams, laxatives, lubricants). When attached to various protein medications, polyethylene glycol allows a slowed clearance of the carried protein from the blood. This makes for a longer acting medicinal effect, reduces toxicity, and allows longer dosing intervals. HILIC separation can be used to determine polyethylene glycol content in various formulations using ELSD, RI detection, or LC/MS detection. HPLC separation of oligomers can be achieved by changing the amount of acetonitrile.
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers. Inquire about our specially-tailored custom LC-phases for specific separations.
SIELC Technologies usually develops more than one method for each compound. Therefore, this particular method may not be the best available method from our portfolio for your specific application. Before you decide to implement this method in your research, please send us an email to research@sielc.com so we can ensure you get optimal results for your compound/s of interest.
