Signet MN Septa - Are capable of being pierced and resealing time after time
without pieces of the septa being deposited in the GC inlet system. These premium
septum are ideal for autosamplers with up to 400 injections per septum.

Signet HT Septa - are capable of being pierced and resealing time after time
without pieces of the septa being deposited in the GC inlet system, do not
contaminate or bleed material into the chromatographic system.

Signet GP Septa - provide a reliable seal against the carrier gas pressure in the
inlet. Capable of being pierced and resealing time after Ɵme without pieces of the
septa being deposited in the GC inlet system

Signet EC Septa - combine significantly longer injection life, high temperature with
low injection port adhesion

Advanced Green Septa - combine significantly longer injecton life, low bleed and low injection port adhesion.

Marathon Septa - are an advanced GC septum for autosampler use, with significantly longer life.

BTO Septa - are Bleed and Temperature Optmized

Greyhound Chromatography supplies the most extensive range of ferrules available from any single supplier, manufactured from Vespel, Vespel/Graphite, Graphite and PTFE. The ferrule size refers to the size of the compression fittng and the OD of the tubing to be used.

Graphite Ferrules - are made from high purity graphite. Ideal for glass to metal connections because they don’t stick to glass. They are reusable, if they are not over tightened.

Vespel®/Graphite (85% Vespel/15% Graphite) Ferrules - are made from quality DuPoint polyimide/ graphite blend. Recommended for GC/MS interface applications.

Vespel/Graphite (60% Vespel/40% Graphite) Ferrules - are made from quality DuPoint polyimide/ graphite blend. Recommended for GC/MS interface applications.

Vespel® Ferrules - are made from 100% high-temperatureDuPont polyimide with precision drilled ID. Vespel is fairly hardand tends to seal permanently to the column.

Our extensive range of capillary columns are designed and manufactured to the most exacting andrigorous standards. Materials of the highest quality and attention to every detail of the manufacturingprocess, results in columns which ensure excellent and reproducible performance for even the mostdifficult types of samples.

Q-Col GenSphere ODS-1 is a totally endcappedpacking with an exceptionally high level ofdeactivation, which minimises interfering interactionswhen analysing strongly acidic or basic analytes orchelating compounds. GenSphere ODS-1 is highlystable at pH values of 1.5 to 11.0.

The Merlin MicrosealTM from Greyhound Chromatography is a microvalve alternative to the conventional silicone rubber septa used in gas chromatography (GC).

Puresep T Septa - Are general purpose septa, faced with a double layer of polyimide and PTFE on one side. They are applied in special applicatons requiring the polyimide barrier layer.

Puresep P Septa - are General purpose septa, red-orange in colour and have a thin FEP layer on the outside of the polyimide film. They are applied in special applications requiring the polyimide barrier layer.

Three Layer Septa - Three Layer Septa are made of preconditoned silicone rubber and are 3.81 mm (0.150”) thick.

HT Septa - High Temperature Septa are made of preconditoned PTFE/silicone rubber and are 3.175 mm (0.125“) thick.

The new Q-Col Spheripak™ HPLC silica has beenspecially developed to replace Waters Spherisorb™ oneof the most popular packings on the market today.

Similar to the Q-Col GenSphere ODS-1 columns, ourGenSphere ODS-2 columns have a high selectivityfor hydrophilic and polar compounds, which are oftenpoorly retained on conventional ODS columns.
