"GC Columns"

Supplier: Restek

General purpose columns for arson accelerants, essential oils, hydrocarbons, pesticides, PCB congeners (e.g. Aroclor mixes), sulfur compounds, amines, solvent impurities, simulated distillation, oxygenates, gasoline range organics (GRO), refinery gases.

Supplier: Thermo Fisher Scientific

These columns are manufactured for better column-to-column reproducibility.

Supplier: HAMILTON BONADUZ

GC on-column syringes with three choices of needle: Stainless steel fixed (N), stainless steel removable (RN) or fused silica removable (RNFS).

Supplier: Thermo Fisher Scientific

High thermal stability column ideal for volatile organic analysis.

Supplier: Thermo Fisher Scientific

These low bleed columns are specifically designed for the analysis of pesticides and it is mainly useful for applications requiring a higher temperature.

Supplier: VARIAN

VF-624ms columns set a new standard for the analysis of volatile organic compounds.

Supplier: Thermo Fisher Scientific

Application-specific columns for blood alcohol analysis.

Supplier: Merck

Inlet liners used in an GC require an O-ring placed near the top for proper operation. This O-ring ensures that the only path for carrier gas to get to the outside of the inlet liner is through the grooves in the inlet seal at the bottom of the injection port.

Supplier: Thermo Fisher Scientific

These columns are ideal for the separation of active environmental compounds such as PAH's and pesticides.

Supplier: Restek

These Rt-XLSulfur columns are optimised for low ppbv sulfur analyses. Interior wall and the end fittings of Rt-XLSulfur columns are Sulfinert treated, making the column as inert as PTFE.

Supplier: Restek

Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and DEX columns continue to demonstrate stability after hundreds of temperature program cycles. 2,3-di-O-methyl-6-O-tert-butyl dimethylsilyl beta cyclodextrin added into 14% cyanopropylphenyl/86% dimethyl polysiloxane.These are excellent column for most chiral compounds in essential oils.

Supplier: Restek

Optimised for pesticide analysis by US EPA Method 608.

Supplier: AGILENT HEWLETT PACKARD

DB-5ms non-polar, low-bleed columns feature an improved signal to noise ratio for excellent sensitivity and mass spectral integrity of aromatic compounds.

Supplier: AGILENT HEWLETT PACKARD

DB-1701P is bonded, cross-linked and solvent rinsable, delivering excellent performance in the analysis of organochlorine pesticides.

Supplier: AGILENT HEWLETT PACKARD

DB-5.625 is specially processed to exhibit excellent inertness for EPA semivolatile methods 625, 1625, 8270, and CLP protocols.

Supplier: Restek
