SOFTWARE COMPLEX NETCHROM

Program «NetChrom V 2.1» Program allows to carry out simultaneous processing of signals and control of one or several (up to eight) chromatographs on single IBM PC. Chromatographs are connected to serial interface RS-232C or to USB interface.

Program provides control and processing of chromatographic signal of the following models of chromatographs:

«Crystallux-4000M»
«Crystallux-4000» (after replacing of master controller of chromatograph)
«Crystall-2000» (connected to PC with the help of standard pairing device)
«Petrochrom-4000»
«LGH-3000»
«Kupol-55».

Program also provides processing of chromatographic signal of non-automated chromatographs like LHM-80, model 3700, Tsvet series and others, including foreign. Chromatographs are connected to PC through the unit of analog-to-digital conversion (ADC).

PROGRAM WORKS WITH FOLLOWING TYPES OF ADSS

24-discharge ADC unit designed by “Meta-chrom” (from 1 to 8 inlets)
24-discharge device DLCM designed by “Meta-chrom” (1 inlet)
24-discharge ADC designed by “MultiChrom” (from 1 to 8 inlets)
24-discharge ADC «E-24 L» designed by «L-Card» (from 1 to 4 inlets).

Programs provides control and processing of chromatographic signals of the combined complex that consists of the set of named above chromatographs and ADCs in different combinations.

PROGRAM WORKS ON IBM PC WITH THE FOLLOWING CONFIGURATION
