Raptor™ ARC-18 LC Columns

Restek Corp.

The Raptor™ ARC-18 column is made specifically for high-throughput, low–sample prep LC-MS/MS applications. A well-balanced retention profile offers better detection and integration of large, multiclass analyte lists, and steric protection helps this SPP column endure the harsh, low-pH mobile phases needed for mass spec without sacrificing retention or peak quality. Restek chemists became the first to combine the speed of supe…

Cannabidiolic Acid (CBDA) Standard

Restek Corp.

Diluted and DEA-exempt—no need to purchase costly neat materials or make your own standards. Pair with Restek's THC standards to analyze both neutrals and acids in cannabis products by LC. A must for accurate quantification in medical cannabis potency testing and strain ID. Acetonitrile solvent helps maintain stability by preventing methylation of the carboxylic acid group on the molecule. Certified reference materia…

Rxi®-PAH Columns

Restek Corp.

The Rxi®-PAH GC columns were designed by Restek with a higher phenyl-content stationary phase that provides unique selectivity to separate important polycyclic aromatic hydrocarbons (PAH) for food safety that cannot be distinguished by mass spectrometry. Even difficult priority compounds, such as the European Food Safety Authority (EFSA) PAH4, are easily separated and accurately quantified, results that cannot be achieved on…

Rtx®-CLPesticides Columns

Restek Corp.

Improved resolution and faster analyses, compared to 1701 or phenyl phases, make these the pesticide columns of choice. Rtx®-CLPesticides columns are specially designed to overcome the coelutions and analyte breakdown typically encountered in chlorinated pesticide analyses for EPA Methods 8081, 608, and CLP. By achieving baseline resolution of the 20 target analytes, more accurate qualitative data can be obtained, providing r…

Raptor™ C18 LC Columns (USP L1)

Restek Corp.

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. Every LC lab has a cache of C18s, but every C18 is not created equal. Because t…
