ProCHRO GC Platform
|
ProCHRO was developed by MPSI under a supply agreement with a major chemical engineering company for use as a transportable process measurement tool. It analyzes two process streams and has the additional capability to have five gas standards on-line for automatic full multi-point calibration. While the instrument was initially developed using a halogen specific detector (XSD) for chlorinated species, we are expanding the detection base to include helium discharge (HID) and thermal conductivity (TCD) detectors for more general analytical capability.
ProCHRO can be used in a Class 1Division 2 hazardous location using purge & pressurization means and integral vortex temperature management system, or it can be used as a laboratory instrument with door fans. It occupies less than 2 cu ft excluding the gas conditioning system and laptop computer. It has an embedded SBC and micro-controller for data acquisition and instrument control. |
Transportable field useThe transportable model is designed to fit into a custom Pelican 1690 transport case. All required components, accessories, tools, and consumables fit into this case to make field use convenient.

Core GCProCHRO uses a Core GC concept which is a unitized closely coupled assembly for valving, fluidics, separation columns, and detection systems. We incorporate resistively heated low thermal mass column technology that enables rapid heating and cooling resulting in faster analysis times. This method also facilitates the use of multiple temperatures with different programming rates to accommodate the unique temperature requirements for each column in a multidimensional or multi column application. The Core GC constitutes an application module and can be configured to address other applications inside the basic GC mainframe.
MPSI develops custom Core GC modules to customer application requirements. OPC data outputProCHRO uses fully integrated Canary Labs Data Historian, TrendLink, TrendCalc, and TrendExport software tools. The Enterprise Historian has tags for component name, retention time, peak area, peak height, molar concentration, peak asymmetry, peak width, elution temperature, resolution, and plate count. These tagged data can be displayed versatilely in both "real time" and on an historical basis using TrendLink. TrendCalc is used for extended calculations using any tagged data. TrendExport is used to export data from the historian to .CSV or .XML formats for import into other graphics or spreadsheet programs.
