Great column.
Pharmaceuticals
This is a very reliable column. After repeated uses and injections we get the same consistent results.

Great column, great service!
Forensic seized drug analyses
This column is almost perfect for seized drug analyses. Secondary amines (such as methamphetamine and MDMA) need to be base extracted for that nice, narrow peak, and d9-THC likes to hang around, but otherwise I am very satisfied with this column. The customer service at Restek has also been great!

Great results.
Drinking Water - Herbacides/Pesticides
We've used these columns for years and they are superior to other vendors. They are always shipped out to us in a timely manner and we can always count on their reproducibility. We test at or below NYS drinking water quality standards and these columns always deliver.

Rt-2560 Columns Ensure Accurate, Reliable AOAC 996.06 and AOCS Ce 1j-07 FAMEs Analysis
Restek’s Rt-2560 GC column was originally developed for detailed analysis of FAMEs in foods and food products. Its highly polar biscyanopropyl stationary phase and long column format make it an effective tool for the difficult task of separating and accurately quantifying complex mixtures of FAMEs. Recently, Restek optimized the manufacturing process and implemented a new, application-specific, QC-testing procedure for all new Rt-2560 columns (cat.# 13198). As shown here, Rt-2560 columns produced using the optimized process exhibit excellent performance for both AOAC 996.06 and AOCS Ce 1j-07 FAMEs analysis and meet all method requirements.
Whole Air Canister Sampling and Preconcentration GC-MS Analysis for pptv Levels of Trimethylsilanol in Semiconductor Cleanroom Air
Damage to scanner lenses by Trimethylsilanol (TMS) in cleanrooms in the semiconductor industry has resulted in the demand for accurate and reliable methods for measuring TMS at trace levels. This application note describes a whole air canister-based approach for field sampling TMS in air, as well as a preconcentration GC-MS laboratory method for analysis.
