Cannabis Testing Products & Reviews

Restek has raised the bar with a new high-temperature MXT®-Biodiesel TG column line to complement their fused silica column line for biodiesel analysis. These new MXT® -Biodiesel TG columns are stable to 430°C and offer unique retention gap options that minimize dead volume and leaks.

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.

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.

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…

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.

Deactivation - unbelievably low breakdown for accurate and precise low-level GC analyses.

Low-polarity phase; Crossbond diphenyl dimethyl polysiloxane

Pro EZGC Chromatogram Modeler Propels Method Development Forward

QuEChERS methods are fast, easy, and cost-effective, and Restek Q-sep products make QuEChERS procedures even easier. No specialized glassware is required when you’re using Q-sep extraction packets and tubes. Free-flowing extraction salts and salt packets that fit easily into the extraction tubes make transferring the salts to your sample mess-free and easy.

Restek offers a full range of porous polymers, including HayeSep and Porapak polymer packings for analyses of volatile compounds and light solvents.

Removes up to 135 ml of oxygen or 2 g of water.

Flowmeters that can measure flammable gases are becoming mandatory due to the increased use of hydrogen in chromatography. With its Ex rating, the Restek ProFLOW 6000 meter is designed specifically with explosive and flammable gases in mind.

Midpolarity crossbond phase general-purpose columns for alcohols, oxygenates, PCB congeners (e.g., Aroclor mixes), pesticides, and fragrance compounds. Equivalent to USP G46 phase.

A low- to midpolarity phase application-specific columns for volatile organic pollutants. Recommended in U.S. EPA methods for volatile organic pollutants. Temperature range: -20 °C to 240 °C. Equivalent to USP G43 phase. The unique polarity of the Rtx-624 column makes it ideal for analyzing volatile organic pollutants. Although the Rtx-502.2 column is recommended in many methods, the Rtx-624 column offers better resolution…

A low- to midpolarity phase general-purpose columns for residual solvents, alcohols, oxygenates, and volatile organic compounds. Equivalent to USP G43 phase.   Many analysts feel the Rtx-1301 column has the best cyanosiloxane bonded stationary phase available, with no other column manufacturer providing lower bleed, longer lifetime, or better inertness. The polymer is fully characterized to ensure long-term reproducibili…

A highly polar phase; biscyanopropyl polysiloxane—not bonded

SilcoSmooth Stainless Steel Separate permanent gases, including carbon monoxide and carbon dioxide, without cryogenic cooling. Rapid separations of permanent gas/light hydrocarbon mixtures. Excellent compatibility with most GC detectors—minimal bleed, minimal baseline rise. Preconditioned, less than 30 minutes to stabilize. Maximum temperature of 280 °C/300 °C.

By adding β or γ cyclodextrin to our bonded Rtx-1701 stationary phase, we greatly enhance overall utility and column lifetime for our chiral columns, compared to columns that have pure cyclodextrin stationary phases. Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and our columns continue to demonstrate stability after hundreds of temperature program cycles. What are ch…
