Users can take a complex single-train chromatograph analysis and break it into multiple simple trains. Each of these simple trains is then run simultaneously, in parallel. Breaking chromatography into parallel operating modules allows the use of standard configurations for common applications. For example, 95% of the vapor thermal conductivity detector applications in a typical olefins plant can be done with various combinations of less than 12 total standard mini-applications. Each of these measurements can be performed in less than two minutes. Standard application modules and methods can be installed in the analyzer.
