Next Level GC-MS

G908 is an all-in-one, multi-column, plug-and-go device. This rugged 28-pound analyzer combines the separation speed of ballistic gas chromatography, the compound selectivity of high pressure mass spectrometry (HPMS), and the analytical capabilities of FID and TCD, to provide rapid qualitative and quantitative results. The unique alliance of capillary column separations, conventional GC detection and novel microscale ion trap technology, ensures reduced analysis times – from minutes to seconds – for a wide range of compounds, saving you time and money. G908 is the most flexible solution for inline, at-line, laboratory and remote field based qualitative and quantitative analysis.

The Big Idea Behind Tiny Footprint Analysis

HPMS is literally the act of performing mass spectrometry at much higher pressures – 10,000 times less vacuum than a conventional MS. HPMS not only enables several key components of the mass spectrometer to be miniaturized, it also completely removes the need for large, continuously operating vacuum pumps that limit deployment of conventional mass spectrometry within production environments.

A Ballistic Approach to GC

G908 integrates the speed and separating power of ballistic gas chromatography with ultra-compact, low maintenance and rugged high pressure mass spectrometer (HPMS). With the unparalleled selectivity and sensitivity of GC-HPMS, G908 can rapidly identify and quantify specific compounds, including low-level impurities, within complex product stream matrices.

Speedy, Single Stream Results

With JetStream, G908 provides users with the most flexible solution for inline, at-line, laboratory and remote field based qualitative and quantitative analysis.

This operator-friendly control and data analysis package combines data from multiple detectors into a single stream of quantitative results wherever they are needed.




The volatile organic compounds benzene, ethylbenzene, toluene and xylene (BTEX) occur naturally in crude oil and seawater near natural gas and other hydrocarbon deposits. Manmade BTEX sources include chemical manufacturing, vehicle emissions, accidental spills and underground storage tank leaks into soil and groundwater.

Natural Gas

Natural Gas

With composition driving natural gas pricing, a traditional C1-C5 separation with C6+ backflush grouping is no longer sufficient to quantify BTU. The accurate identification of longer chain constituents, along with fixed gases and corrosive sulfur species, such as H2S, significantly improves gas value. While Gas chromatography (GC) is the method of choice for standard natural gas measurement, GC–mass spectrometry (GC-MS) is better suited for more challenging extended analyses.



Rapid, accurate determination of ethers, alcohols, aldehydes and ketones, present in many hydrocarbon process streams, is a recurring challenge. Even the residual traces of these compounds can inactivate costly, high-yield catalysts commonly used for large-scale polymer production. Unfortunately, todays standard gas chromatography (GC) methods for oxygenate analysis are not suitable for ever decreasing detection limits.

Sulfur Speciation

Sulfur Speciation

Natural, refinery, landfill, sewage digester and other fuel gases contain volatile sulfur compounds such as hydrogen sulfide, carbonyl sulfide, and mercaptans that are corrosive, poisonous and subject to regulation. Municipal distribution of the methane fraction as fuel requires both production and distribution facilities to accurately determine sulfur content. Fuel gases are also feedstocks for polymer production where the catalysts involved are poisoned by sulfur compounds.
