We offer a wide selection of autosampler and general-purpose vials, including septa and vial accessories for sample collection, storage, and processing.
headspace vapor from the vial and transferring it to the GC column. Figure 3 shows a chromatogram produced from a headspace sample taken from the same
Some sample vials have low adsorption, but the results show low consistency in reproducibility. Other sample vials even have worse recovery rate of compounds.
Whereas GC and HPLC are predominantly automated procedures, sample pre-treatment is often added to increase rate of extraction; safe; rapid; best for.
provide a unique capability for rapid, cost-effective and quantitative measurements of organic sample preparation and calibration strategies.
