Replacement Parts for Dionex ASE® Systems
Accelerated solvent extraction has become a common technique for fast and reliable extraction of
organic materials from solid matrices. Restek now offers several direct replacement parts for ASE®
extraction systems, including extraction cells, caps, frits, and PEEK® washers. In addition to stainless
steel extraction cells—equivalent to original parts—we offer cells, caps, and frits finished with our
innovative Siltek ® treatment. Siltek® treatment reduces the surface activity of stainless steel, greatly
improving inertness and, therefore, the reliability of analytical results for active compounds. All of our
replacement parts for ASE® systems are designed to meet or exceed original equipment manufactur-
er's performance. Look to Restek to keep your extraction systems running smoothly.

EPA Method 521
For use in EPA Method 521, Nitrosamines in
Drinking Water. This method uses large vol-
ume injection and CI, MS-MS. Activated
charcoal for NDMA.

SPE Tubes for US EPA Method 521
Newly proposed US EPA Method 521 is designed for the analysis of 7 nitrosamines in drinking water.
This method employs a 6mL solid phase extraction (SPE) tube packed with 2 grams of coconut charcoal
to extract and concentrate the nitrosamines from the aqueous matrix.
We perform a batch test on each lot of coconut charcoal we use to prepare these new tubes, to ensure
consistent recoveries and low background. High quality polypropylene tubes and frits are used to mini-
mize interferences.
