pfa测试

im体育APP performs PFAS testing to precisely measure their presence in 水, 土壤, 废物, 泡沫, 混凝土和更多. Our team support you by identifying PFAS compounds in parts per trillion to mitigate environmental contamination and protect human health.

什么是PFAS?

Poly- and perfluoroalkyl substances (PFAS) are a large group of synthetic organofluorine chemicals that have been widely used in industry and manufacturing since the 1940s, 包括不粘锅等应用, stain-repellent服装, 快餐包装, 美容化妆, 还有消防泡沫. They are found at many manufacturing and waste/waste水 treatment facilities as well as in the wider environment.

All PFAS have at least one fully fluorinated methyl (–CF3) or methylene (–CF2–) group, with the carbon-fluorine bonds (C–F) imparting high thermal stability and resistance to degradation, 使它们在各种各样的产品中都很有用.

为什么要检测PFAS?

PFAS化合物具有持久性和生物蓄积性, 这意味着它们不会在环境中分解, 并且可以很容易地迁移到空气中, 水, 土壤, 和食物. They are often known as 'forever chemicals' and are attracting widespread interest due to their harmful effects on human health.

随着对PFAS化合物的认识的出现, regulatory interest often focused on Perfluorooctanesulphonic Acid (PFOS) and Perfluorooctanoic Acid (PFOA), 两种最常用的PFAS物质. However there are >5,000个已知PFAS和监管范围, 客户需求和分析能力, 正在迅速扩张.

使用im体育APP进行PFAS测试的主要好处

• 综合分析: im体育APP提供跨不同样品的PFAS测试, 包括水, 土壤, 空气, 消费产品, 和更多的.
• 低级的检测: 利用先进技术, im体育APP achieves detection levels in the parts per trillion range, ensuring precise identification even at trace concentrations.
• 监管依从性: 所有测试都遵循美国环保署的方法, with ISO17025 accreditation for low-level PFAS testing in 水域, 确保符合公认的标准.
• 目标物质清单: 50种物质的im体育APP测试, aligning with EU Drinking 水 Directive and DWI requirements, 满足法规和特定客户的需求. We offer customized method development to identify PFAS substances not on target lists.
• 先进的设备: 最近对先进设备的投资, 如Agilent 1290 HPLC 6495三重四极杆质谱, 确保结果准确. Our laboratories are ISO 17025 accredited, enhancing the reliability of results.

我们的测试能力

We work closely with customers to deliver on the analyses to quantify PFAS compounds in the parts per trillion range. All testing is based on USEPA methodologies, samples include:

• 水
• 土壤
• 浪费 产品
• 消防泡沫
• 混凝土

im体育APP提供了PFAS液相色谱检测, 结合串联质谱法, 自2015年以来. im体育APP’s Deeside(英国) laboratory has recently invested in an Agilent 1290 HPLC 6495 Triple Quadrupole MS, which can achieve the required regulatory detection levels without requirement for additional sample preparation. Deeside holds ISO17025 accreditation for the testing of Low Level PFAS in 水域.

PFAS compounds need to be quantified in the parts per trillion range, 需要高度敏感的测试方法. Our team are experienced in meeting these stringent detection levels. In addition, we also offer the Total Oxidisable Precursor Assay, or ‘TOP’ assay. 这可以在土壤上进行, 水域, 还有消防泡沫, and is a more comprehensive analysis technique for identifying the presence of some other PFAS or precursors not included in the target list.
