The Adept CE 4200 is a detector of the highest specification and versatility covering the range 190 -700 nm with an optical bandwidth of approximately 8 nm. It may be used standalone, or it may form part of any system controlled by PowerStream software.
Dual wavelength operation allows two wavelengths to be monitored simultaneously with their ratio also being available. Full programming using up to six wavelengths is also possible.
Noise and drift performance are of the very highest order, ±0.35 x 10-5 A peak-to-peak, and ±0.3 x 10-4 A respectively.
Up to 30 methods may be created and stored, password protected, ensuring reproducible conditions when recalled. An auto switch-on programme saves operator time during warm-up.
HPLC Analysis of Organophosphate Pesticides
Organophosphate pesticides irreversibly inactivate acetylcholinesterase, which is essential to nerve function in insects, humans, and many other animals. Organophosphate pesticides degrade rapidly by hydrolysis on exposure to sunlight, air, and soil, although small amounts can be detected in food and drinking water. In this application note from Cecil Instruments a method for the analysis of organophosphates is demonstrated. Methyl parathion, Dichlorvos, Ethoprophos and Azinphos were efficiently separated using the Hypersil Hypurity Aquastar RP18 analytical column and the Adept HPLC Series System 2 with on-line solvent degasser and CE 4200 UV-Visible detector.
