The right process gas chromatographfor every measuring taskThere are numerous, varied areas of application in process analysis and each user expects their analyzer to meetdifferent requirements. Our MicroSAM, SITRANS CV and MAXUM edition II process gas chromatographs will provideyou with just the right solution for each and every application.MAXUM edition II and its incredible versatilityThe versatile MAXUM edition II combines various analyticalmodules of different types in one system. This broadbasis means that you can use the MAXUM edition II for allyour different measuring tasks. This significantly reducesyour costs for capital investment, training and spare parts.• The most versatile chromatograph in the world, thanksto a variety of detector types such as FID, WLD, FPD,ECD, HID, PID, which can also be combined into multidetector configurations.• A flexible oven concept with energy-saving airlessovens and airbath ovens (also available in temperatureprogrammableversion). They are all available as dualovens. This configuration makes it possible to implementone complex application or two simple applications withjust one device, where you would otherwise require twoseparate chromatographs. The new modular oven is thenew standard for concise and quick maintenance andhigh measuring uptime.• Parallel chromatography divides a complex applicationinto several simpler sub-applications, which are thenanalyzed simultaneously. This reduces cycle times andfacilitates maintenance.• The patented, valve-less live column switching technologyhas been a tried-and-tested feature of our chromatographsfor many years. It contains no moving partsand is chemically inert, making it maintenance-free.• Electronic pressure controllers provide accurate pressurecontrol without the need for throttles or needlevalves, which is ideal for our live column switching.• State-of-the-art TCP/IP communication and Ethernetstandard hardware mean compatibility with a widerange of different networks. This simplifies communicationbetween chromatograph, computers and operatingpersonnel.• On-site operation with the Color Touch Screen HMI issimplicity itself.

Small size, big performance – MicroSAMWhether you want to refurbish an existing system orare planning a greenfield project, space-saving is alwaysan important issue in the process industry, and a clearcase for MicroSAM. If the micro process GC is installedtogether with traditional process gas chromatographs(PGCs), significantly smaller analyzer shelters are requiredat significantly reduced costs. When combined with auser-friendly remote operation concept, the MicroSAMallows for field-mounted operation directly at thesampling point. This is particularly advantageous in thoseinstallations where analyzer shelters cannot be used forreasons of space or cost. But the MicroSAM is not only anattractive solution in these situations. It is also recommendedfor installation at remote locations with limitedinfrastructure and restricted maintenance potential.• Lower operational costs due to reduced carrier gas andpower consumption; no instrument air necessary• Protection from sun and rain is provided by a canopy or asimple enclosure, rather than using an analyzer shelter• Shorter sample infeed, return, and waste lines• Lower sample extraction volume• Reduced engineering and installation time and costs• Use of MAXUM edition II software reduces trainingrequirements• Communication interfaces and network connection asfor the MAXUM edition IIThe MicroSAM offers considerable economic advantageswhen compared to traditional PGCs, both in the initialinvestment and life-cycle costs:• Simple analyzer maintenance, even without expertknowledge• Fast and simple replacement of the analysis moduleinstead of replacing or repairing individual analyticcom ponentsMAXUM or MicroSAM: Which device is best suited to my application?Do you have an application where space in theanalyzer shelter is a critical factor?Do you need a solution which can be integratedinto your complete system without a great dealof investment cost?Are you looking for a device which can taketime-critical measurements as part of complexapplications?Do you find that device maintenance takesa long time and is very complicated?Do you need a gas chromatograph for sampleswith complex compositions, trace detection orfor liquid samples?The most up-to-date silicon-based micromechanics are integratedinto the MicroSAM. This allows the size of the deviceto be reduced to that of a football while increasing its performanceat the same time.The compact and rugged design of the MicroSAM means itcan be integrated into the process environment simply andcost-effectively.The parallel chromatography of the MAXUM edition II enablesthe distribution of complex applications to several simple units,which shortens analysis times and improves the device serviceability.The average maintenance time for the MicroSAM and MAXUMedition II modular oven is half an hour. And the service can becarried out by staff with practically no training. This increasesthe availability of your plant.The MAXUM edition II enables applications like temperatureprogrammedanalyses, trace analyses with special detectors orthe analysis of liquid, complete and undecomposed vaporizablesamples.5

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
