The sequences are programmed at a defined time and everyone can perform analyses as desired.analyses are programmed to run continuously.the operator programs a defined number of analyses.There are three main choices when programming the sequences: flow rate, temperature or humidity, etc.), or the injection of the sample into the gas chromatograph is initiated, etc.
#Agilent chemstation series
For each analysis, it is also possible to define a series of timed material events: a relay actuates a valve, or an external analog value is recorded (e.g.
#Agilent chemstation software
The programming of the analysis sequences (up to 999 lines) allows to define for each row the flow to be analyzed, the Chemstation method and the conditioning time of the line in this way, the software anticipates the switching of the line selection valve and reduces the analysis time. ProChem controls up to 16 sampling streams from single electrovalves or VICI Valco© multi-position valves with electric or pneumatic control. ProChem also ensures the management of the streams selectors (up to 16 positions), the acquisition of external analog signals, the management of alarms and the transmission of results in analog 4-20 mA or digital Modbus. Additional modules are available for calculating the physical properties of the gas being analyzed or for customized calculations.
The graphs of the different work sections are intuitive and easy to use, and the graphical tools simplify the display of analysis results in table or graph form. The intuitive user interface of the ProChem software allows for immediate supervision, automation and sequence programming. Each Agilent gas chromatograph can be coupled with ProChem. The Agilent workstation software can manage up to four instrument sessions independently for each computer. ProChem software, designed by SRA Instruments, is a monitoring software that extends the capabilities of Open Lab Chemstation CDS and Open Lab CDS to the field of online GC analysis and automation management.
