НТ2100H Equilibrium Vapor Samples Autosampler

Headspace autosampler for equilibrium vapor samples

  1. General Details

    Autosampler “HT2100H” (manufactured by “HTA s.r.l.” Italy-Brescia) is designed for automatic injection of equilibrium vapor samples (Headspace autosampler) into chromatographs of “Crystallux” series.  This way, volatile components from matrices, the ones that shouldn’t be injected, or can not be injected into the chromatograph, are injected into chromatograph. Examples of such matrices are drinking and waste water, soil, biological fluids, food products and drinks, various polymers, building materials, pharmaceutical products, etc. Autosampler realizes static injection method of equilibrium vapor from above the analyzed liquid (solid sample) in thermostated vial. During work with chromatograph of “Crystallux” series sampler control is realized directly from chromatograph software without running additional programs.
