Equipment Used by Pesticide Analytical Technology • High Performance Liquid Chromatography (HPLC): With Diode Array detection (DAD) and a wide variety of columns able to separate the compound of interest from any interference. With the DAD it is possible to generate an unique Ultra Violet spectrum of the analyte which can be used for identification purposes. This technique is especially useful to analyze temperature sensitive compounds. • Gas Chromatography (GC), Mass Spectrometry (GC-MS): The MS technique makes it possible to identify or to confirm the identity of a compound by means of the retention time and spectrum. The compound is separated from interferences on a selective column at a high temperature, where after it is ionized to from a mass spectrum. • Essential Small Laboratory Equipment: Balances, Ultrasonic Water baths, Incubators, Moisture analyzers sect.
