Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.
