Volatile Organic Compound Sampler Used to collect non-aerated samples into 40 mL glass vials for volatile organic compound analysis. The volatile organic compound sampler can be submerged to a specific water depth. US DH-95 Isokinetic Sampler, Including:
Analytical Method A total of 59 semi-volatile compounds included under Directive 2013/39/EU were analyzed. Three internal stan-dards were used for quantification: DDE-4,4´-d8, Terbutryn-d5 and Benzo(a)pyrene-d12. The acquisition method (Figure 2) was created

During volatile analysis, samples are purged with an inert gas in order for the Volatile Organic Compounds (VOCs) to be swept out of the sample matrix and onto an analytical trap. For years, the established purge flow rate and time has been 40ml/min for 11 minutes.
Standard vials have fitted black phenolic caps with either polycone liner or PTFE faced white rubber liner Also available: pre-cleaned EPA (Environmental Protection Agency) vials for VOA (volatile organic analysis), with or without certification, having fitted white
further initiates a series of chain reactions with hydrocarbons (i.e., volatile organic compounds, VOCs), nitrogen oxides (usually in the presence of light) to form compounds such as ozone and other oxidants including aldehydes, peroxyacetylnitrate
In this application note, we demonstrate a novel technique – large volume preconcentration (LVP) – for enhancing traditional headspace analysis of trace-level volatile organic compounds (VOCs) that contribute to aroma and flavour in tomato paste. Using the Centri ® sample extraction and enrichment platform in headspace–trap mode, the extracted analytes are preconcentrated on an
