Cannabis Testing Products & Reviews

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…

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…

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…

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…

midpolarity phase; Crossbond® trifluoropropylmethyl polysiloxane

Force LC columns are available with Restek's most popular and highly selective Biphenyl and FluoroPhenyl phases, as well as a general-purpose C18.

The culmination of 20+ years in LC, Force performance LC columns are long-lasting and reproducible, even under the stress of UHPLC. Premium quality is backed by the strength of our 100% Pure Satisfaction guarantee. And perhaps most important, Force columns are fully scalable between 3 or 5 μm HPLC and 1.8 μm UHPLC, so you can easily transfer and optimize methods without extensive calculations.   Force FluoroPhenyl LC…

Deactivation - unbelievably low breakdown for accurate and precise low-level GC analyses. Reproducibility - unbeatable manufacturing controls and QC testing for superior reliability across compound classes. Productivity - unparalleled cleanliness for maximized GC uptime and lab throughput.

Low-polarity phase; Crossbond diphenyl dimethyl polysiloxane General-purpose columns for drugs, solvent impurities, pesticides, hydrocarbons, PCB congeners (e.g., Aroclor mixes), essential oils, semivolatiles. Equivalent to USP G27 and G36 phases. Temp. Limits: -60 to 325/340 °C Similar To: Agilent 122-5033, 19091J-233; Phenomenex 7HG-G002-22; Varian CP8771; Grace 13657, 5121840, 8635223 Le…
