挥发性有机化合物(VOC)测试与分析

Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) are chemicals widely used in industrial processes that are highly regulated due to the risks they pose to human health. Element performs SVOC and VOC testing to help ensure compliance with all applicable standards.

Element is a system of laboratories with advanced capabilities that allow us to conduct SVOC and VOC testing in both consumer products and in samples from the environment. With the use of several large 环境 chambers and a microchamber, 我们可以进行精确的VOC测试 汽车产品, 建筑材料、办公用品等 furniture. 我们还测试如下的矩阵 water, soil, waste, oil, ambient air, soil vapor, and off-gas from car components.

产品和环境中的挥发性有机化合物

Regulations require VOCs and SVOCs to be tested at extremely low concentrations. Exposure to some of these chemicals has been linked to a variety of health issues. It is critical to ensure that your products and materials comply with safety guidelines and legislation restricting the use of substances. Element employs a variety of test methods to evaluate a range of material types and can assist with virtually any VOC or SVOC testing project, 包括排放测试. 

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. im体育APP提供了高容量, accurate testing required to ensure you meet highly stringent regulatory guidelines and clean-up requirements.

挥发性有机化合物测试及抽样

我们使用多种仪器，包括 气相色谱/质谱 热解吸，顶空GC/MS和吹扫 & 陷阱GC / MS), Gas 色谱法 with flame-ionization detection (GC-FID) and High Pressure Liquid 色谱法 (HPLC).

元件提供以下取样介质:

• 解吸管
• 泰德拉袋
• 真空罐和真空瓶
• VOC vials
• 甲醇防腐剂
• DNPH墨盒

We can advise on the best sampling media to use to minimize VOC losses and maintain the integrity of the sample. 

Element provides 环境 testing for a wide range of VOC’s in drinking water, 地下水, 地表水, 土壤和废物. Element can also check for other VOC contaminants such as Bromodichloromethane, Bromoform, Chloroform, Dibromochloromethane, 和总三卤甲烷. We ensure tests are right first time, and carried out as quickly as possible.

甲醇保存的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).

吸收管上的VOCs

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 analyzed 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.

罐中的挥发性有机化合物

真空罐(Suma型罐), 瓶子和泰德勒袋可以用来取整个样品. 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小时或24小时. These are particularly useful to obtain both ambient and vapor intrusion samples.

产品VOC检测

Element employs a variety of methods to sample VOC emissions from products and materials using tedlar bags, mircochamber抽样, 热解吸和各种尺寸的试验箱.
