HPLC Method for Glycerol, Xylitol, Sorbitol, Erythritol, Ethylene Glycol on Primesep AP by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Glycerol, Xylitol, Sorbitol, Erythritol, Ethylene Glycol.
Ethylene glycol is an organic compound with the formula (CH2OH)2. It has a variety of uses, but it is primarily found as an antifreeze agent. Those coolants are often used in automobiles and air-conditioning systems. In the plastic industry, ethylene glycol is a precursor to polyester fibers and resins.
Glycerol is an organic compound with the molecular formula C3H8O3. It is a humectant, solvent, and sweetener that used in various industries including skin care, hygiene products, pharmaceuticals, and food. It is said to improve lubrication and smoothness in products. Historically, before ethylene glycol took over, glycerol was used as a antifreeze.
Erythritol is a naturally accruing sugar alcohol with the chemical formula C4H10O4. It is is typically used as a sweetener and flavor enhancer in a large variety of foods and bevarages, including but not limited to tea, juice blends, soft drinks, cookies, biscuits, sugar-free chewing gum, and confections. It does lead to a noticeably different texture in baked products if used as a sugar replacement.
Xylitol is a sugar alcohol with the chemical formula C5H12O5. It is primarily used as a sugar supplement in confections, toothpaste, and drugs. It is considered a safe option for those with diabetes as it has negligible effects on blood sugar. It is said to produce a cooling sensation when interacting with moisture, which makes it an interesting additive to textiles.
Sorbitol is a sugar alcohol with the chemical formula C6H14O6. It is used primarily as a sugar substitute, but it also provides some dietary energy. Medically, it can be used as a laxative. In modern cosmetics, it is also used as a humectant and thickener.
Glycerol, Xylitol, Sorbitol, Erythritol, Ethylene Glycol can be retained and analyzed using the Primesep AP stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN). Detection is performed using UV.

HPLC Derivatization and Quantitative Analysis of Glycerol
July 16, 2010

Glycerol is a polyol hydrophilic compound which is used in pharmaceutical formulations. It is also a byproduct of biodisel production through transesterification. Glycerol has three hydroxyl groups, making it a very polar compound. Method using periodate/acetylacteone derivatization was developed using UV. Method is fast and shows good linearity within explored range of concentrations. This general HPLC approach can be used for precise quantitation of glycerol.
