The COMAC is windows application used for controlling of chromatographic process, communication with chromatographic devices and storing data for next evaluation. Application supports variant devices for liquid chromatography such as pumps, detectors, column ovens etc., especially those produced by the company. Main aspects of application are: Simple usage Support CoMetro's with communication interface General interpretation of devices and measured properties Supporting variant export formats Low hardware requirements for application itself Runnable on all 32-bit Windows operation systems Open source Languages: English Software COMAC is designed with maximal effort to do easy operation of chromatographic systems CoMetro. It is suited for units controlling and data collecting. Equipments are connected to the PC using RS232, or USB (by means of RS232/USB converter). Software detects automatically almost of all units, so there is no need complicated communication installation: Program most important features: Easy installation Connecting using USB or RS232 No need A/D converter Possibility to start up to 8 stations at the same time Data export in various formats Possibility of external start and external mark Secured access Units controlling and data collecting from one place Equipments are controlled using well-arranged menu, each installed unit has own bookmarks: On the screen we can watch parameters of all units for example detector absorbance, pump pressure and column oven temperature. It allow monitoring of whole system by stabilization or by problems searching. It is possible to record, print and export all data. Supported formats by data export: Text formats: native text format, two column text format and CSW Clarity text format Binary formats: native binary CH-format, CSW (1.7) Raw format, Matlab5.0(Octave) MAT format, AIA NETCDF  Start of data collecting and eventual marks (for example by fraction collecting) is it possible to do using keyboard or using external unit.
