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’s Rt®-Silica BOND columns are robust, versatile, selective PLOT columns that offer excellent performance for the analysis of light hydrocarbons, sulfur gases, and halocarbons above ambient temperature.

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…

Improved resolution and faster analyses, compared to 1701 or phenyl phases, make these the pesticide columns of choice.

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.

for Agilent 6890 and 7890 instruments.

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.

Don't let a small leak turn into a costly repair—protect your analytical column by using a Restek leak detector. Audible tone indicates the severity of a leak. Redesigned circuitry offers 12 hours of operation between charges. Detects a broad range of gases; Ex rated for use with hydrogen and other explosive gases.

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

Switch to a Raptor HILIC-Si LC column when you need more retention and resolution of hydrophilic, polar analytes. HILIC silica column designed for increased retention of polar compounds without ion-pairing reagents. 2.7 μm Raptor core-shell particles provide the speed of SPP, with greater efficiency and capacity than 5 μm particles. Ideal for increasing sensitivity and selectivity in LC-MS analyses. Fully compatible with both…
