    GOW-MAC Series 816 HighPerformance Gas Chromatograph

    SB-816

    A unique combination of technologies

    The GOW-MAC Series 816 High Performance GasChromatograph combines the industry’s leading digitalGC platform with advanced detector technology. Theresult is a complete, high caliber gas chromatographcapable of the accuracy, reproducibility and sensitivitydemanded by today’s analytical chemists and theirunique applications. The Series 816 GC featuresperformance in all the area you expect: productivity,dependability, data management, ease of use, GLPcompliance and modular engineering for easy executionof upgrades and service.

    Ready for your application — out of the box

    The advantage offered by the Series 816 GC is that itcan be supplied as a fully customized GC platform withdetectors and unique flow systems. Whether it’s EPA,GPA, ASTM, or some other method, our chemists andengineers address every facet of your application, i.e.,sample preparation and management, sample injectionmethods, pneumatic controls, detectors, columns, dataoutput — everything. Every custom configured Series816 GC is supplied with full analysis documentation andguarantee of analysis. We assume total systemresponsibility, right out of the box.

    Performance to meet the most challenging tasks

    The Series 816 GC is a dual channel gas chromatographwith electronic pneumatic control (EPC) of all pneumaticfunctions allowing for faster system setup andequilibration. It has an easy to use alphanumerickeyboard with color coded softkeys and simple keysequences. All GC parameters can be digitally recorded.A run log records all system conditions including anydeviations from pre-selected set point values. The Series816 GC, when used with a PC, can be equipped for offsite diagnosis of system problems should they occur. Allpneumatics, inlets and detectors are modular for simplermaintenance. The Series 816 GC can also be housed ina process enclosure for protection from variousenvironmental elements specific to the customer’srequirements. For special applications involvingcorrosive materials, the Series 816 GC system can beconstructed with corrosion resistant materials.

  • Digital pressure and temperature control

    In addition to EPC, the Series 816 is equipped with sensors to monitor andcompensate for temperature and barometric pressure, The result is a gaschromatograph with exceptional stability requiring less frequent calibration.

    EPC provides precise digital control of all pneumatic functions directly from theinstrument’s keyboard. The advanced pneumatic design reduces the risk ofcontamination and leaks in the system. Carrier and detector gas flow are easierto implement and control for more efficient use of consumables. The Series 816GC also features a gas saver function to reduce gas flow between sample runs.

    Rapid analysis is provided with higher oven temperature programming rates,including clock time programming that allows for automatic preparation of thesystem for the first analysis of the day. Operating temperatures are independentlycontrolled at six zones in addition to the column oven. Valves are thermally isolatedfrom the oven’s heating cycles.

    Operating the instrument

    The user interfaces with the Series 816 GC through a simplealphanumeric keyboard with easy to use color coded soft keys andbasic key sequences. The system programming cycles and instrumentstatus including oven temperature ramp are clearly indicated withlight emitting diode (LED) displays. The four line liquid crystal display(LCD) communicates analysis conditions in uncomplicated language.The simple tough of a soft key brings the user into immediate controlof the GC — real time chromatograms, editing features, methoddevelopment and setup, etc. A key marked INFO provides helpfulanswers if needed. Automatic valve control, sequence control, pre-run events and post run programming are all accomplished from thekeyboard.

    Versatile sample injection choices

    GOW-MAC offers users several injection modes to meet their needsfor accuracy, reproducibility and efficiency.

    Split/Splitless injection

    Split/splitless injection modes with increased sensitivity through larger volumeinjections are achieved with the advanced pneumatics offered by the Series 816 GC. Thesplit/splitless capillary inlet is designed so that the split mode is back pressure regulated forevery setting of split ratio, and the splitless mode is forward pressure regulated. The resultis minimal sample discrimination and degradation.

    Packed column injection

    Packed column injections with increased precision are achieved by utilizing the system’s electronic flow controlcapabilities. Accommodates metal or glass columns. Direct sample injection to wide bore (0.53 mm) fused silicacapillary columns can be either flow (720 mL/min.) or pressure controlled.

    Total system integration and responsibility...one source, one guarantee!

  • Flexible valve design

    Unique to the Series 816 GC is GOW-MAC engineering department’s ability toprovide virtually any flow configuration. Gas sampling and column switchingcapabilities are provided through a variety of gas sample valve configurations.Depending upon the intended method, the Series 816 GC can support up to tencolumns as well as up to seven automated valves for a single application. Optimumseparation and precise quantification is assured by selecting from 4, 6, 8 or 10-port valves. Each valve can be controlled directly or in sequence for different gasstreams. EPC allows programmable control of sample valves allowing injectionseither continuously or at programmed intervals. Column switching is supportedby the ability to change valve positions as a function of the chromatographic run.Valves are pneumatic actuated and can be temperature controlled, purged, orconstructed of corrosion resistant materials.

    Direct liquid injections onto the head of the column are allowable with temperatureprogrammable cool on-column features.

    Cooled injection system (CIS) minimized sample discrimination during deliveryto the column or to separate low boiling point components selectively.

    Data handling capabilities

    The automation and communications features of the Series816 GC can be interfaced by various data handling devices,each complementing specific customer requirements

    Software

    GOW-MAC offers a variety of interactive PCchromatography data software packages. Each differsin the degree of remote instrument control andrequested comprehensive data handling and reportingcapability.

    Integrators

    Essential data reporting and manipulation can be accomplished with the use ofmost commercially available computing integrators.

    The Series 816 GC is equipped with an RS-232-C data interface port, two analogoutput channels (1 mV, 1 V, and 10 V), and one IEEE-488 parallel port for interfacingto modems, plotters and various other devices as standard. INET interface is optional.

    GOW-MAC Detectors

    The Series 816 GC can handle virtually any application: petrochemical,semiconductor, food, flavor, solvent or industrial chemical. GOW-MAChas manufactured hundreds of thousands of detectors since theinception of gas chromatography, including award winning andpatented detectors. The Series 816 GC accommodates single or dualdetector configurations. Each independently temperature controlleddetector can operate either individually, in series, or in parallel modes.
