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).

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.

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. The bonding mechanisms produce a col…

With Raptor™ LC columns, 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. SPP core-shell columns commonly employ traditional phe…
