GC packed columns and capillary columns

GL Sciences GC Columns are designed and manufactured in Japan and offer the lowest bleed levels, the best inertness for acids/bases/mixed functional compounds, and the tightest column-to-column reproducibility.

We supply both capillary columns from very standard till very exclusive versions. Packed columns for gas chromatography are also produced in Japan, we have both Glass and SUS versions with many different packings.

Available capillary columns:1MS, 1, 1HT, 5MS/Sil, 5MS, 5, Pesticides, 624, 1301, 25, 35, 1701, 17MS, 17, 210, 225, Pure-WAX, WAX, WAX-HT, FFAP and fast GC Columns.

There are so many different versions available, please contact us and give us information about your GC model, liquid phase, phase loading, on what support material, support mesh size, column material, column dimensions and aging or not.

The human nose is an incredible detector for aroma/mal-odour components. Gas Chromatography Olfactometry (GC-O) is a bioassay that measures human response to odorants separated by gas chromatography.

The superior sensitivity and selectivity of human olfaction make GC-O a powerful and meaningful tool for flavour chemistry. Head-space sampling, distillation, solvent extraction, solid phase micro extraction (SPME) and our DMI are typical procedures used to introduce samples in a GC-O. Besides providing data about the potency of odorants extracted and separated for samples, GC-O can also be used to study variation in human olfaction or provide testing and training of panellists used in sensory testing. At its best, GC-O, provides industry with a link between chemical data collected from ingredients or products and the sensory and consumer preference data collected from the market place. At the very least GC-O data derived from a product can be used for quality control or the development of value added products.

The PHASER Pro GC-O or GC Olfactometry

The PHASER Pro is the latest edition of the sniffing port. A temperature-programmable transfer line is introduced in this instrument, that can be programmed as the GC oven. This results in a stable split ratio (sniffing flow rate/detector flow rate). Heat stress at the nose and thermal degradation of the compounds are prevented, making it possible to perform olfactory detection with higher accuracy and sensitivity.

The transfer line has been designed in such a way that there are no cold spots along the line. This allows high precision evaluation of odors. High-boiling or adsorptive compounds are not trapped inside the transfer line. The target compounds are obtained without loss.

• No cold spot gives the possibility to sniff the high boiling compounds.
• Transfer line is hot till the end
• Transfer line can be programmed in temperature
• Maximum 300°C on the transfer line.
• Protects your nose from drying by adding moist air to sniffing port.
• Easy to connect the capillary column to the splitter.
• Sitting down or standing up while sniffing.
• Compact and easy to install on any GC instrument.
• SplitManager software standard supplied.
• Voice recording with replay function.

The PHASER is standard supplied with all capillaries, 4 port microchannel connector, nuts and ferrules and SplitManager software in order to make the installation. Only a GC mounting plate kit is needed.

Increase in Sensitivity with our cryotrap the CryoFocus

With CryoFocus-4 (Stand alone or integrated in OPTIC-4) analytes are focused at the head of the column by cooling its selected section to sub-ambient temperature. After re-focusing, the analytes are released from the GC cryotrap in a very narrow band using an extreme fast heating rate of 60 °C/second. As a result, very sharp peaks with a high signal to noise ratio are obtained.

Can be used on any GC or GCMSStand alone or integrated in OPTIC-4Operating using direct LN2 or CO2New from January 2023 is our silent LN2 valveTemperature range:  -150 °C to 350 °CTemperature stability at low temperature:  ±3 °CHeating ramp rate: 1 to 60 °C/secCool down time:  2-3 minutesCompatible with any GCSoftware controlled by Evolution WorkstationSoftware compatible with Chronos MastersoftwareFree software updates

A Preparative Gas Chromatograph system can collect the target compounds which were separated by Gas Chromatography. The VPS2800 GC fraction collector is designed to work with capillary columns and gives high recovery and pure fractionation. It is possible to collect just a part of a peak, one peak or a group of peaks with the GC fraction collector.
The preparative gc collection tube is available in two versions, a glass and a metal version. The minimum trapping temperature of -60°C is achieved with a Stirling cooling technique that is standard available in the VPS2800 GC fraction collector. With the easy to operate software, you just select a peak in the chromatogram or set a time window in order to collect a peak.

After collection, the components of interest can be transferred to other analysis techniques like NMR or UV/VIS or be used for reanalysis on GCMS.

Strong points

• Automated collection of compounds
• Six collection traps and one waste
• No valves and no cold spots for best possible recovery
• No carry over by unique flow path
• Deactivated sample flow path
• Flow path can be heated till 380°C
• Software control for easy set-up
• Cooling without LN2

HandyTD is an easy thermal desorption device for manual thermal desorption. The instrument has its own gas control, it needs only the main supply from the carrier gas line. HandyTD has a needle that is inserted into the inlet of the host GC and a gas frow from the HandyTD will push the sample to the GC inlet. The colour display will guide the user to the operating steps. The size of the tubes used in the HandyTD are ¼ x 3½ inch, this is the size of the standard available thermal desorption tubes. The HandyTD can only be used with glass tubes.

Strong points

• Space-saving design
• In-house patented technology achieves a fast heating rate
• Compatible with any GC instrument
• Easy touch panel operation without PC
• Wizard function to navigate trough the operating procedure
• Sample is direct injected into the GC
• Equipped with electronic flow control (EPFC)
• Tube / liner size is industry standard TD tube: 1/4 inch version (OD= ¼ x 3½ inch = 6.35 x 88.9 mm)
