Successful process analytics require morethan just a gas chromatographThe considerable benefits of gas chromatography can be fully exploited when the outstanding technologiesof MAXUM edition II, MicroSAM and SITRANS CV are combined with other factors.Application“Application” is the term used for customer-specificsystem adaptation to the measuring task. It is here thatthe strengths of the MAXUM edition II, MicroSAM andSITRANS CV show their full effect. Our applicationsspecialists are involved in the process right from the start,bringing years of experience with hundreds of applicationswith our gas chromatographs. They configure thedevice, according to detailed customer specifications,including the oven, detectors, valves and separationcolumns. The appropriate solution is then developed inclose collaboration with the customer and introducedduring the factory acceptance test.Sample conditioningThe quality and reliability of the measured values of a gaschromatograph are in direct correlation to the quality ofthe samples fed into the device. Sample conditioning is anintegral part of a reliable analytical solution and furthermoreis responsible for 50–80 % of maintenance costsand analyzer-related downtimes. We recommend sampleconditioning geared to the gas chromatograph in order toensure the highest level of reliability and simplified maintenance.The future will see a trend toward increased automationof sample conditioning. If the sample conditioningprocess can supply additional measured data such asflow rate, temperature, and pressure, this could help todiagnose faults at an early stage and, as a result, reducemaintenance expenditure.Data managementReliable communication between analyzers and thecontrol system is vitally important for process control.While SITRANS CV is fitted with the operator softwareCVControl necessary for custody transfer, the independentanalyzers MAXUM edition II and MicroSAM use the samesoftware and infrastructure for communication. With thehelp of this infrastructure, measured values can be transmitted,further calculated or corrected if necessary andparameters can be set and modified.In addition, calibration and validation processes can betriggered and tracked and status signals (also externalones) scanned and processed. Alternatively, our AnalyzerSystem Manager (ASM) can take over these functions.TechnologyApplicationSamplepreparationDatamanagement10
