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. Available in Biphenyl, FluoroPhenyl, and C18 phases.
Restek's new cannabidiolic acid (CBDA) reference standard is diluted and DEA-exempted—so there's no need to purchase costly neat materials or to make your own standards. Paired with our existing THC standards, this recently released reference material is perfect for the analysis of both neutrals and acids in cannabis products by LC. Restek’s new CBDA certified reference material (CRM) meets strict ISO requirements and is a must for accurate potency testing and strain ID.
Topaz inlet liners deliver inertness you’ll have to see for yourself to believe. The new deactivation technology means unbelievably low breakdown for accurate and precise low-level GC analyses.
