Element provides the high volume accurate testing required to ensure you are meeting Volatile Organic Compounds highly stringent regulation guidelines, clean-up regulatory requirements and protection of human health.
Volatile organic compounds (VOCs) are volatile compounds that contain carbon. They are commonly used or produced in industrial processes and are also found in fuels and used as solvents. VOCs are of concern due to their low boiling points, extensive use, relatively high toxicity, and a high degree of halogenation.
Testing and Sampling for VOCs
Element provides VOC testing on various matrices such as waters, soil, waste, oil, ambient air, soil vapour, and off gas from car components. Element uses state-of-the-art equipment and robust methods to reach the low detection levels and most methods/matrices are accredited to ISO 17025.
We use a variety of instruments including Gas chromatography / Mass spectroscopy (Thermal Desorption and Headspace GC/MS), Gas Chromatography with flame-ionization detection (GC-FID) and High Pressure Liquid Chromatography (HPLC).
Element provides the following sampling media:
- desorption tubes
- Tedlar bags
- evacuated canisters and BottleVacs
- VOC vials
- methanol preservatives
- DNPH cartridges
We can advise on the best sampling media to use to minimise VOC losses and maintain the integrity of the sample.
Element provides testing for a wide range of VOC’s in drinking water, ground water, surface water, soil and waste. Element can also check for other VOC contaminants such as Bromodichloromethane, Bromoform, Chloroform, Dibromochloromethane, and total Trihalomethanes. We ensure tests are right first time, and carried out as quickly as possible.
Methanol Preserved VOCs
There are many ways of sampling soil for VOCs, each with advantages and disadvantages. Element can provide sample kits for the methanol preserved VOC analysis in accordance with BS 10176 (UK) and EPA Method 5030 (US/Canada).
VOCs on Sorbent Tubes
Element can provide sorbent tubes for air quality sampling of VOCs. Tubes can be sampled either passively or pumped with the VOCs being trapped onto the sorbent media. The tube is then either thermally or solvent desorbed and analysed for target VOCs including chlorinated solvents, a general screen (top 10 GC-MS peaks) or TPH CWG including BTEXN. Element can advise on which sorbent tube to use depending on the volatiles of concern and the required sampling period.
VOCs in Canisters
Evacuated canisters (Suma type canisters), BottleVacs and Tedlar Bags can be used to take whole samples. The canisters and Bottlevacs are dispatched under vacuum with a sample train. Depending on the sample train provided and the container volume the equipment can be used to take samples over either a few minutes, an hour, 8 hours or 24 hours. These are particularly useful to obtain both ambient and vapour intrusion samples.
