The perfect solution when there is a need for rapid and reliable tests for carbon and/or nitrogen in samples coming from a variety of natural, domestic and industrial sources. The FORMACS™ Series is ideal for fast, reliable determination of carbon species and nitrogen by high temperature catalytic combustion in a wide range of environmental samples. The FORMACS™ HT is designed to measure TC, IC, TOC, NPOC, POC and DOC in cleaner sample types, whether in large batches with a 150-position autosampler or as a stand-alone model. The FORMACS™ HT-i is especially useful with particulate laden samples and suspensions in mind, with its direct injection mechanism and wide-bore pickup and injection needle. Both models can be extended with the measurement of TN/TKN and the semi-automatic analysis of TC and IC in solids.
