挥发性有机化合物(VOCs)和半挥发性有机化合物(SVOCs)是广泛用于工业过程的化学品,由于它们对人类健康构成风险而受到严格管制. Element执行SVOC和VOC测试,以帮助确保符合所有适用的标准.

Element是一个拥有先进能力的实验室系统,使我们能够在消费品和环境样品中进行SVOC和VOC测试. 使用几个大型环境室和一个微室, we can perform precise VOC testing for automotive productsbuilding materials, office products, and furniture. We also test matrices such as water, soil, waste、油、周围空气、土壤蒸气和汽车部件的废气.

 

VOCs in products and the environment

法规要求在极低浓度下测试挥发性有机化合物和挥发性有机化合物. 接触其中一些化学物质与各种健康问题有关. 确保您的产品和材料符合安全指南和限制使用物质的立法是至关重要的. Element采用多种测试方法来评估一系列材料类型,并且可以协助几乎任何VOC或SVOC测试项目, including emissions testing. 

Element使用最先进的设备和强大的方法来达到低检测水平,大多数方法/矩阵都通过了ISO 17025认证. Element provides the high-volume, 准确的测试要求,以确保您符合高度严格的法规指导方针和清理要求.

 

VOC testing and sampling

We use a variety of instruments including Gas chromatography / Mass spectroscopy (Thermal Desorption, Headspace GC/MS and Purge & Trap GC/MS), 气相色谱-火焰电离检测(GC-FID)和高压液相色谱(HPLC).

Element provides the following sampling media:

  • desorption tubes
  • Tedlar bags
  • evacuated canisters and BottleVacs
  • VOC vials
  • methanol preservatives
  • DNPH cartridges

我们可以就最佳取样介质提供建议,以尽量减少挥发性有机化合物的损失,并保持样品的完整性. 

Element为饮用水中广泛的挥发性有机化合物提供环境测试, ground water, surface water, soil and waste. Element还可以检查其他挥发性有机化合物污染物,如溴二氯甲烷, Bromoform, Chloroform, Dibromochloromethane, and total Trihalomethanes. 我们确保测试第一次是正确的,并尽快进行.

 

Methanol preserved VOCs

土壤中VOCs的采样方法很多,各有优缺点. Element可根据BS 10176(英国)和EPA方法5030(美国/加拿大)提供甲醇保存VOC分析的样品试剂盒。.

 

VOCs on sorbent tubes

元件可提供吸附管,用于VOCs的空气质量采样. 管道可以被动采样,也可以泵送,将挥发性有机化合物捕获到吸附介质上. 然后对管进行热解吸或溶剂解吸,并分析目标挥发性有机化合物,包括氯化溶剂, 一般屏幕(前10个GC-MS峰)或TPH CWG,包括BTEXN. Element可以根据所关注的挥发物和所需的采样周期建议使用哪种吸收管.

 

VOCs in canisters

Evacuated canisters (Suma type canisters), BottleVacs and Tedlar Bags can be used to take whole samples. 罐和瓶在真空条件下与样品列车一起运送. 根据所提供的样品序列和容器体积,该设备可用于在几分钟内取样, an hour, 8 hours or 24 hours. 这对于获取环境和蒸汽侵入样品特别有用.

 

VOC testing for products

Element采用多种方法对使用塑料袋的产品和材料的挥发性有机化合物排放进行取样, mircochamber sampling, thermal desorption and various size chamber testing.

 

The Element advantage

Element拥有支持您的项目和测试需求的专业知识、设施和技术诀窍. 我们可以为制药im体育平台app下载的广泛应用提供挥发性有机化合物的采样和分析, residual solvents, impurities from drug substances and container closure systems, flavor, fragrance, and packaging, petrochemical, environmental, and polymers industries. 

Our testing laboratories in North America, the United Kingdom, the Middle East, and Asia, 和南非提供全套服务,并为您的测试需求提供定制报告.
