Calidus MicroGC

Faster, Smaller, Smarter, Easier and Greener than Traditional Gas Chromatographs
General Specification
  • Operating Environment
    • Operating Temperature Range: 0°C to 35°C
    • Storage Temperature Range: -20°C to 60°C
    • Relative Humidity Range: 0 to 100% (non-condensing)
  • Power Requirements
    • Less than 300 watts peak power at startup, practical use < 200 Watts for gas or liquid analyses 24 VDC supplied from external power supply, 100-240VAC using 50/60Hz AC
  • Safety
    • General purpose, light industrial (lab instrument environment) CE Mark and Nationally Recognized Testing Laboratory (NRTL) certified (TUV Rheinland) pending.
  • Gas Supplies
    • 50 PSIG, 99.995% hydrogen at up to 250 ml/min, 50 PSIG Zero air for FID operation.
  • Sample Requirements (via split/splitless injector with septum purge)
    • Air or gaseous samples. Membrane, SPME and static and dynamic headspace extracts. Direct liquid injections neat or dilute organic solvents (DCM, Hexane, MEK, Toluene, methanol, etc.)
  • Dimensions
    • 17" wide by 8.5" deep by 11" high, ~ 25 lbs. Uninterrupted power supply and data acquisition computer external to the base unit.
  • Controls/Outputs
    • All functions and parameters can be set via Ethernet or USB. Start analysis can be triggered from the instrument display panel or by method from an external computer running ChromPerfect SoftwareTM. Column signals are digitized for each column in 24-bit resolution, the FID at 100 Hz and TCD at 50 Hz. ChromPerfect also supplies a full array of control and processing options for other analyzer functions and settings
  • Front Panel Displays
    • The front panel is an LCD touch screen supplying temperature and pressure readings, function on/off, power on/off, status of analysis columns (isothermal, programming, cool down, ready, and cycles run)
  • Performance (application dependent)
    • Repeatability of ± 1% RSD or better (area) and of ± 0.1% RSD or better (retention times). Analysis times for VOCs can be < 20 seconds and for SVOCs < 60 seconds. Dynamic range depends on detector used and application (FID typically 105).

FASTER - With analytical cycles 10 to 50 times faster than traditional gas chromatography, the CALIDUSTM microGC vastly increases responsiveness for the data consumer. Less time spent waiting on results means more productivity and timely control of the measured process. In the hands of lab and process managers, the speed of the CALIDUS microGC can translate into better quality products, produced faster and more profitably than ever before.


SMALLER - Elimination of the air bath column ovens, required for traditional gas chromatography drastically reduces the CALIDUSTM micro gas chromatograph footprint. Yet, the CALIDUS microGC delivers all the functionality of the much larger, high thermal mass, traditional GCs. At less than 25 pounds, CALIDUS offers advanced analytical chemistry in a highly compact and transportable package. The smaller size of the CALIDUS microGC means more efficient utilization of space and, ultimately, bigger profits for the user. The price per square foot for laboratory bench top space may only be exceeded by the cost of installation for online systems in the processing plant. The small CALIDUS footprint allows for higher installation density in the laboratory and in shelters for process applications. This small footprint also enables process installation schemes that place the analyzer much closer to its sampling point in the plant. Closer proximity means less sample lag time, as well as more representative measurements for process control. CALIDUSTM microGC with optional autosampler and laptop interface


SMARTER - Using modern computing with standard operating systems and software, the automated CALIDUS microGC frees valuable technical resources from the daily grind of interpreting and validating chromatographic results. Built-in LineUpTM technology from Infometrix, Inc. virtually eliminates misidentification of components and drastically reduces the need for expensive calibration sample runs. Less time spent calibrating the analyzer means more time spent on more economically valuable diagnostics, most notably measured process deviations from the setpoint.


EASIER - Proprietary, plug and play temperature-programmed gas chromatography column modules allow the CALIDUS microGC to avoid the complicated and troublesome valve schemes used in isothermal process analyzers and many lab gas chromatographs. Global patents are pending for this unique micro gas chromatograph. Correlation between laboratory systems and online process control systems becomes realistically possible with the CALIDUS microGC, because both physical packages use the same measurement principle, hardware and methodology. Applying the CALIDUS microGC in-lab and online means less time spent reconciling lab and process measurements and validating which result is correct. More time can be spent working on more valuable, direct process optimization.


GREENER - The obvious and extraordinary features and benefits of the CALIDUS microGC combine to yield something that may not be that evident: Green Process Analytical Chemistry. CALIDUS is greener - whether in the control laboratory, online in the processing plant, near line in the pilot plant or when transported for field measurements. Consuming less than 300 Watts in operation, the CALIDUS microGC uses a small fraction of the traditional gas chromatograph consumption rate of up to 3000 Watts. With analytical cycles that are a minimum of 10 times faster and the low electrical load needed for operation, the CALIDUS microGC power consumption per analysis is 1% or less of the energy required by traditional gas chromatography. Combine these savings with the reduction in workload for air conditioning systems and the CALIDUS solution is greener still. The CALIDUS product life cycle environmental impact from manufacturing throughout its useful lifetime to disposal is far less than traditional GCs.


THE RESULT - Faster, Smaller, Smarter, Easier and Greener = better quality, increased productivity, profitability and versatility, with far less hassle and environmental impact. That summarizes the successful, business application equation for the CALIDUSTM microGC.
