Tedlar^® 气体采样袋

NB.24

The EPA Toxicity Characteristic Leaching Procedure (TCLP) was implemented in 1990 for determining the mobility of organic and inorganic contaminants present in liquids, solids and multiphasic wastes. The TCLP provides a method to determine the potential for any waste leaching in a landfill environment;, according to this procedure, a pressure driven piston system, Zero Headspace Extractor (ZHE), forces liquid waste through a glass fiber filter and into a Tedlar bag for subsequent analysis.

Supelco offers our disposable 1 Liter Tedlar bag for use with the Zero Headspace extractor (ZHE). It features a single stainless steel septum fitting that is designed to be connected to commercially available extractor vessels using a special stainless steel adapter (not sold by sigma-aldrich).
Tedlar已被推荐用于US EPA的几种方法中，用于对VOC和硫化合物的取样。我们的Tedlar产品采用优质2 mil Tedlar薄膜制成，具有出色的惰性/不渗透性/样品完整性和良好的回收率数据。我们的推锁阀(PLV)和接缝密封工艺确保这些袋子牢固且防漏，即使在最苛刻的取样和运输条件下也是如此。
