Cannabis Testing Products & Reviews

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 with existing HPLC and UHPLC instrumentation.

for Agilent 5880A/5890/6850/6890/7890 GCs with S/SL or PTV inlets

Usable to 340 °C inlet temperature

Gold plating provides enhanced inertness versus stainless steel.

Use 1/16-inch, two-hole ferrules with the 1/16-inch capillary inlet adaptor fitting kit (cat.# 27185). Use 1/8-inch, two-hole ferrules with the 1/8-inch capillary inlet adaptor fitting kit (cat.# 20645).

Separate a wide variety of polar analytes with a novel hybrid stationary phase

The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications.

Include the most common consumable GC supplies and tools

for Agilent GCs with 5971/5972, 5973, 5975, or 5977 GC-MS  

Designed specifically for semivolatiles (SVOC) analysis, Restek’s new Rxi-SVOCms columns are designed to provide consistent performance that will keep calibrations passing longer so more samples can be run before needing to recalibrate the instrument or replace the column.

General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, and US EPA Method 603 (acrolein/acrylonitrile). Resistant to oxidative damage. Temperature range: 40°C to 260°C. Equivalent to USP G14, G15, G16, G20, and G39 phases. The polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns.

Restek's new line of fused silica capillary GC columns - Rxi® columns - is now available! 

Restek's former Rtx®-17 columns are now manufactured using new Rxi® column technology--for unsurpassed inertness, ultra-low bleed, guaranteed reproducibility, and unmatched performance!
