Because of their extensive use in plastics, phthalates of various types are now ubiquitously present in the environment. The fact that they can migrate into foodstuffs, can bioaccumulate, are toxic and poorly degradable means that they are of concern from a health and safety perspective. To protect consumers, many methods have been developed to qualitatively and quantitatively detect and measure phthalates, with chromatography being the method of choice. Irrespective of the method used, there is a requirement for high quality, well characterised phthalate standards. Reagecon offers a significant range of such standards which can be used for calibration, verification, quality control and method validation of chromatographic equipment.
