Our products are used to digest, extract, and separate components of chemical mixtures. We offer preconfigured systems for analysis of Volatile Organic Compounds (VOCs) in water, soil, and solids. Our pHDetect is an optional & external module for the Eclipse 4660 Purge-and-Trap (P&T) sample concentrator that automates measurement and recording of pH values for Volatile Organic Compound (VOC) water samples. We also design WinFLOW, which gives the most advanced instrument control and data acquisition software package for flow analyzer systems.
