standard graphite ferrules (for GC applications)

Vespel® ferrules contain 15% graphite and are ideal for glass and fused silica capillary columns.

A complete line of Brass and Stainless Steel Fittings for GC, MS and general laboratory use.

SIS offers two types of PEEK tubing: Solid color coded tubing, and natural tan tubing with a color coded stripe.

The top fitting of both purge heads consists of a 1/16" fitting for the attachment of the sparging needle followed by needle adaptor to seal the needle in place and provide for the attachment of the purging gas line.

The Purge and Trap System consists of two single-ball rotameters with adjustable needle valve mounted on a nylon plastic base with an 18" long mounting rod support.

After conditioning and sample loading, the ends of the tubes are fitted with stainless steel caps with seals to maintain the integrity of the medium and sample.

This Sample Collection System permits the purging of volatiles and semi-volatile components present in solid materials and their trapping on Desorption Tubes packed with an adsorbent resin for subsequent analysis by desorption utilizing the Short Path Thermal Desorption System.

This 24 tube conditioning oven is used for batch flow conditioning of both empty and packed Silco Coated SS desorption tubes as well as for the flow conditioning of the desorption tube needles.

The Desorption Tube Conditioning System is used for the flow conditioning of both empty and packed Silco Coated SS desorption tubes as well as for the flow conditioning of the desorption tube needles.

The following glassware can be used in conjunction with the S.I.S. purge head adaptor to permit the use of the S.I.S. tube style liquid purge head for purging liquid and solid samples and trapping volatiles purged from the samples onto the S.I.S. Thermal Desorption Tubes.
