2008/3/25 · Desorption was performed directly in the gas chromatograph injector port for 5 min at 250 °C using the splitless mode. The proposed method is sensible (with detection limits between 0.0045 and 0.2399 mg/L), precise (with coefficients of variation in the range 0.99–8.18%), and linear over more than 1 order of magnitude.

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Incorporated in the year 2007, at New Delhi (Delhi, India) we Rastech India are recognized as the significant manufacturer and supplier of finest quality Gas Chromatography & Accessories,Gas Control Panels and Gas & Cylinder Regulators.

2020/10/8 · The fiber (which had been conditioned daily according to the manufacturer’s recommendations) was exposed to the headspace gas phase during the warm-up period (4 min). After extraction, the fiber was collected and introduced into the gas chromatograph injector, where it remained in exposure for 3 min.

Recently, commercial headspace samplers have become available with the capability of trapping the gas sample onto a sorbent instead of introducing it directly into the gas chromatograph. With conventional headspace, the analytes are normally present at concentrations ranging from parts per billion to low percentage levels; with trapping, samples with much lower levels of analytes …
