    TurboMatrix Thermal Desorbers for Gas Chromatography

    For laboratories analyzing everything from air quality to flavors and fragrances, thermal desorption offers a faster, easier, more cost-efficient way to prepare samples for GC or GC/MS analysis. Ideal for the trace-level measurement of volatile organic compounds (VOCs)—as well as most semi-volatile chemicals—thermal desorption lets you avoid time-consuming, manual, solvent-based sample preparation in favor of a simple, streamlined, automated approach. It also delivers the added benefits of superior throughput and enhanced sensitivity.

    Ozone Precursor System

    The analysis of C2 to C12 volatile organic ozone-precursor compounds can present a serious technical challenge to the analytical chemist. Low concentrations in the atmosphere coupled with the need to monitor frequently to assess diurnal variations means that a preconcentration step of the sample before analysis by thermal desorption is required. While the samples can be collected in the field and returned to the laboratory, remote, field-based analysis is desired which allows reduced data turnaround time, minimizes sample collection hardware and permits the presence or absence of VOCs to be correlated with meteorological data. In the field, low-molecular-weight C2 VOCs can be trapped on solid adsorbents if those adsorbents are cryogenically cooled.
