1 GenTech Master GC offers a new approach to the world of gas chromatography by dramatically decreasing sample run times in a wide range of GC Applications. This GC is truly customizable to meet each user s needs, while maintaining ease of use. Its modular design allows the user to easily change or upgrade to any GC configuration. Up to three injection units and three detectors can be mounted simultaneously. An intuitive Touch Screen interface controls both the GC and AS with ultimate simplicity. The whole system is completely accessible - allowing easy maintenance and reducing cost. GenTech Master GC includes a complete range of injectors. Specifically, the GenTech Master PTV ensures unprecedented sample integrity and supports the stringent timing requirements of Fast GC through a rapid cool down. GenTech Master GC features a full range of highly sensitive detectors. Each detector incorporates a Digital Pressure (DPC), so the detector gas flow rate can be regulated digitally. The GenTech Master comprehensive line of detectors guarantees a cost-effective solution for all application requirements. Detector data acquisition rate is up to 300 Hz for a better repeatability and accuracy of chromatographic data. Gas sampling valves, auxiliary ovens, switching valves and other optional devices make GenTech Master GC the most suitable gas chromatograph for the development of complex analytical systems in a wide range of applications. GenTech Master GC can be connected directory to DDS ClarityTM Work Station through a local area network (LAN). Dedicated turnkey systems are the "added value" of all GenTech Instruments. The GenTech Master GC, coupled with the GenTech Master Head Space Sampler and GenTech Master TD Thermal Desorber, covers a wide range of applications for environmental, chemical, petrochemical, pharmaceutical, and food and beverage testing.
