Gas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.
Hollow, flow-through plunger with integrated 3-way valve designed for liquid and gases, with a push button on/off valve at the front end. The new Precision Sampling hollow plunger syringe with two integrated valves opens a whole new world of application possibilities: Dispense a viscous sample more easily by introducing it into the rear of the syringe instead of drawing it up through the needle. Eliminate sample-to-sample cros…
The Dual Layer PEEK tubing eliminates any concern that a critical sample stream could be contaminated by pigments used to color code the tubing. The pigmented layer surrounds a separate but integrally-bonded inner layer of natural PEEK. The 1/16" OD tubing is available in standard sizes, or in OEM quantities with any ID you specify, from .002" to .030". The ID tolerance of ±.001" is equivalent to or better than that of tubing…
Thermal desorption (TD) combines sample preparation, extraction, and injection into a single automated process for the analysis of volatile and semi-volatile organic compounds (VOC and SVOC).
The Atlas chromatography data system controls hundreds of instruments from a variety of vendors in compliance with FDA regulations, including 21 CFR Part 11. Atlas was developed in partnership with leading chromatographers to easily configure to any laboratory’s workflow while providing the flexibility to integrate with LIMS and other data management systems for a scalable, compliant solution. The Atlas chromatography data sy…
Septa are an important part of the GC instrument, providing a leak-free seal at the inlet, and require good durability, resealability and low bleed to optimize the performance of your instrument.Septa from Thermo Fisher Scientific are available in several types of materials, described below, to fit Thermo Fisher Scientific's GC and GC/MS instruments as well as other manufacturers’ instruments, matching different application ne…
MicroSAM - The new Dimension in Process Gas Chromatography MicroSAM , the newest on-line Process Gas Chromatograph from Siemens, brings a new dimension to the industry - small! Using modern silicon micro-machining techniques achieves miniature size while simultaneously increasing power and versatility. The explosion-proof enclosure contains everything you need for separation and detection of the measured sample integrated into…
Mid-Polar UI column; a great choice for drugs of abuse testing and pesticides analysis. Agilent J&W continues their ultra inert innovations with the DB-35ms Ultra Inert GC column; a mid-polar column joining the existing apolar columns in the family, DB/HP-1ms and DB/HP-5ms. With this new column, ultra inert performance is available for applications where different selectivity is needed for enhanced separations, including pest…
