Abstract. Accurate mean concentrations of volatile organic compounds (VOCs) can easily and economically be obtained from a single VOC analysis by using proven methods of collecting representative, discrete water samples and compositing them with a gas-tight syringe. The technique can be used in conjunction with chemical analysis by a

VOA Vials are most commonly used for Volatile Organic Compound Analysis. These Vials are Type 1 Borosilicate glass available in Clear and Amber. Vials come with a choice of 1pc 24-414 white cap and sonically bonded septum.
VWR® TraceClean® 40 ml Vials | VWR Type I borosilicate glass vials are for use in volatile organic analyses and are prepared in a solvent-free facility to prevent possible volatile contamination.Water sampling vials are ideal for water sample collection and storage when testing for pollutants.
The presence of volatile organic pollutants could be mostly of automobilist transport near the stations, discharging of wastes from some gas stations or some mechanical industries neat the river.
