Supplier: Agilent

Packed GC columns are designed and manufactured to offer excellent and reproducible performance for all sample types associated with packed column separations, most important in the hydrocarbon processing industry.

Supplier: Thermo Fisher Scientific

TRACE™ TR-5MS GC columns are ideal for hydrocarbons, solvents, pesticides, herbicides, phenols, amines.

Supplier: Thermo Fisher Scientific

These GC columns have a higher phenyl content for useful elution order and retention time changes.

Supplier: Restek

These Siltek treated stainless steel tubing are the most durable high temperature GC columns. High temperature simulated distillation requires a column that can withstand temperatures to 430 °C.

Supplier: Restek

PLOT columns are made from Siltek® treated stainless steel and have the same characteristics and performance as fused silica PLOT columns but useful for GCs and other field applications.

Supplier: Thermo Fisher Scientific

TracePLOT™ TG-BOND Msieve 5A GC columns are designed for separation of Ar/O₂ and other permanent gases.

Supplier: PerkinElmer

Liners protect GC columns against column contamination. These glass split and splitless inlet liners promote full vaporisation of samples, minimise mass discrimination, and achieve accurate and reproducible results.

Micropacked inlet conversion kits are used to convert a capillary GC split/splitless inlet for use with ¹/₁₆" Ext.Ø micropacked columns.

Supplier: Restek

Rxi® fused silica capillary GC columns are designed specifically for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity.

Supplier: Thermo Fisher Scientific

These non polar TraceGOLD™ TG-1MS GC columns are ideal for optimal signal-to-noise ratio, sensitivity and MS integrity for a wide variety of applications. These low bleed, stable columns achieve consistent results.

Supplier: VARIAN

VF-DA is a unique, guaranteed low bleed FactorFour GC column for drugs of abuse confirmation testing. The VF-DA column has high recovery for trace components and excellent resistance to direct methanol injections.

Supplier: Restek

Rxi®-XLB (fused silica) columns are ideal for many GC-MS applications, including pesticides, PCB congeners (e.g., Aroclor mixes), PAHs.

Supplier: Agilent

Before ordering parts for FID maintenance, determine which type of FID is installed on your GC. The FID is available in two versions: Dedicated, capillary optimized: for capillary columns only. Adaptable: for packed or capillary columns.

Supplier: Thermo Fisher Scientific

TRACE™ TR-FAME GC columns are ideal for separation of cis or trans isomers and fatty acid methyl esters (FAMEs) with various degrees of unsaturation.

Supplier: Thermo Fisher Scientific

Employ the most widely used MS phase in gas chromatography with the 5% phenyl phase Thermo Scientific TraceGOLD TG-5MS GC Column. These columns have exceptionally low bleed for optimal signal-to-noise ratio, sensitivity and MS integrity.

Supplier: Thermo Fisher Scientific

These columns are custom-tailored to analyse dioxins and polychlorinated biphenyls (PCBs). Optimised to meet the requirements of high-resolution GC/MS methods, these columns deliver optimum performance with exceptional stability and very low bleed. These low-polarity columns provide wide coverage of the 17 cogeners with the highest toxicological significance (2,3,7,8-chlorine substituted congeners).

Supplier: VWR Chemicals

Due to its excellent separation capacity and its high sensitivity gas chromatography is a widely used technique for analytical purposes. In order to get proper identification and quantification results of the analysed compounds, reference standards are needed. These PESTINORM® reference substances can be used for the characterisation of GC column properties. In addition they may also be used for the identification of unknown compounds in a gas chromatogram or as standards in quantitative GC analysis.

Supplier: Restek

This kit includes a ¹/₄" stainless steel nut and graphite ferrule for attaching the liner to the GC inlet and a ¹/₄ to ¹/₁₆" stainless steel reducer, plus a ¹/₄" and 0,5 mm ID graphite ferrule for attaching the column to the liner.

Supplier: Agilent

These inlet liners prevent adsorption and ensure accurate sample transfer onto the GC column through a robust deactivated surface. These liners are recommended for trace level analysis of active analytes. Liners with inert wool retain non-volatiles, prolonging column life and lowering frequency of MS source maintenance.

Supplier: Trajan Scientific and Medical

Vespel/graphite GC ferrules are made from quality polyimide/graphite blend. They seal with minimal torque and can be reused and repositioned along capillary columns if not over compressed in the fitting. Due to slight shrinking at high temperatures, they must be retightened after initial temperature cycles to avoid leaks.

Supplier: Trajan Scientific and Medical

GLT™ (Glass Lined Tubing) is made by fusing a borosilicate glass lining onto the inside surface of stainless steel tubing. Ideal for HPLC columns, especially biological matrices, GC/MS interfaces, FTIR transfer lines, inlet liners, tee pieces and unions, thermal desorption tubes and SFC.

Supplier: Restek

Foam generated as purge gas passes through a sample can enter the analytical trap and possibly the GC column. This silica-containing antifoam agent is effective over a wide pH range and will not conflict with chromatography of target analytes.

Supplier: Restek

Deactivated Press-Tight® connectors maintain complete inertness along the GC flow path and Siltek®-deactivated connectors are ideal for organochlorine pesticides analysis. These connectors fit 0,33 to 0,74 mm ext. Ø and 0,1 to 0,53 int. Ø columns.

Supplier: Restek

Capillary GC inlet systems have backpressure regulators to maintain a constant upstream pressure and rapidly respond to catastrophic leaks. The operating range 0 to 4,1 bar is sufficient to operate a 105 m, 0,25 mm ID column at its optimum flow rate.

Supplier: Restek

Rxi®-5Sil MS stationary phase incorporates phenyl groups in the polymer backbone. This improves thermal stability, reduces bleed, and makes the phase less prone to oxidation. These columns are ideal for GC-MS applications requiring high sensitivity, including use in ion trap systems.

Supplier: TCI

Application: SILREST (10-50 μL) is directly injected into GC at 150-250 °C of the column temperature. The baseline of the recorder normally stabilizes within several minutes. If not, injection of SILREST is repeated until the baseline stabilizes. Note: SILREST cannot be used for glycerin, polyethylene glycol, other liquid phases having activated hydrogen such as hydroxyl group, thiol group, carboxyl group, amino group, imino group.
