Molecular sieve packed columns easily separate permanent gases at above-ambient temperatures. Restek's R&D chemists have developed a process for preparing molecular sieve packings, which result in excellent batch-to-batch reproducibility. In addition, our molecular sieves are preactivated and ready to use. Each column comes with metal end-fittings to prevent water or carbon dioxide from adsorbing into the packing during shipment.

• Low bleed levels.
• Longer column lifetimes.
• Short conditioning times.

• Available with a variety of packing materials.
• High capacity and retention for volatile compounds.
• Can be coiled to fit any GC.

This 3-column set is finely tuned to resolve light hydrocarbons. When used in the proper valving system, it will elute C5+ hydrocarbons ahead of C1 through C4 hydrocarbons.

This column separates the light hydrocarbons, and baseline resolves cis-2-butene from 1,3-butadiene.

This packed column has unique selectivity for resolving unsaturated light hydrocarbons.

• Use 1/8″ and 3/16″ OD columns in 1/4″ on-column injection ports.
• Centers column perfectly in injection port to eliminate bent syringe needles.
• Slotted design prevents carrier gas occlusion.
• Vespel®/graphite reducing ferrules make installation easy.
• Includes all nuts & ferrules used to attach tubing to the injector or detector.

Pesticide analysis remains the largest environmental application for packed columns. Currently, mixed phase packed columns do not offer complete resolution of chlorinated pesticides, and require long analysis times (nearly 40 minutes).
Restek has developed a special packing material that exceeds EPA Method 608 resolution requirements while delivering a faster analysis time than any other pesticide phase packed column available. Inert SilcoSmooth® tubing and highly inert Silcoport® support make it possible to analyze chlorinated pesticides at levels below 50pg—performance that is nearly impossible with older packed column technology. The computer-modeled phase resolves all 18 peaks in US EPA Method 608 in less than 12 minutes—one-third the time previously required! Compare the performances of conventional 1.5% SP-2250/1.95% SP-2401 pesticide packing and innovative Rt®-608Pkd packing, and you’ll stop wasting time with old technology.
