  • Easy-to-use MON2000 PC software for advanced diagnostics and simplified troubleshooting; simply the best in the industry
  • Rosemount Analytical diaphragm valves offer a lifetime warranty
GAS CHROMATOGRAPH VALVES
The chromatograph valves used in Rosemount Analytical gas chromatographs are unique to the on-line gas chromatograph market. Using a design originally developed by NASA, the valve offers greatly extended operating life. Emerson Process Management is currently the only on-line gas chromatograph supplier to offer a lifetime warranty on their Rosemount Analytical chromatograph valves!
  • Simple mechanical design
  • Sample does not come in contact with internal moving parts
  • More than 5 million operations per valve
  • Lifetime warranty on diaphragm valves
  • Rotary liquid injection valves also available as applications need
The reason for the exceptional durability of the valve is its unique double-diaphragm actuation. The double diaphragm design eliminates the need for springs, O-rings and lubrication. Flow paths in the valve are arranged so that internal moving parts never contact the sample flow. As a result, abrasive mechanical wear on machined valve surfaces is eliminated. The valves are rated for over 5 million operations before repair (approximately 3-5 years of usage). And then, repair is typically simply changing the diaphragms in the valve.

Most importantly, the Rosemount Analytical valve offers excellent performance. Minimal internal movement of the components in the valve – roughly 1/1000th of an inch – contributes to rapid actuation of the valve, which can be important for applications using micro-packed and capillary columns.

DETECTORS
The Rosemount Analytical Model 500 Gas Chromatograph has the selection of detectors to handle the wide range of analytical demands found in typical process applications. Whether the components of interest are in the percent range or down to the parts-per-million range, precise and reliable measurement is possible.

The Thermal Conductivity Detector’s (TCD) thermistor is the detector of choice for most applications due to its universal response to all compounds. Emerson's Rosemount Analytical TCD is able to go well beyond the normal measuring ranges seen in other designs by being able to do many applications with low parts-per-million measurement requirements. This greatly simplifies the gas chromatograph design when a simple and rugged TCD can be used rather than FID.

  • TCD detector is sensitive down to 3 ppm
  • Dual TCD / TCD or TCD / FID configurations possible


HEAT SINK OVEN
The Heat Sink Oven design of the Model 500 brings stable and precise measurement to the field without the need for expensive analyzer shelters.

  • Airless heat sink oven with operating temperatures up to 185°F (85°C)
  • Up to 3 six-port diaphragm valves for maximum analytical flexibility
  • Micro-packed columns mounted in center of heat sink oven for stable performance over the analyzer's entire ambient temperature rating


Installed in thousands of units worldwide, the heat sink oven integrates TCDs, micro-packed columns and gas chromatograph valves in a single temperature-controlled assembly. The entire oven is certified for operation without the need for instrument air – for oven heat or for safety reasons.

COLUMNS
Since 1980, Emerson Process Management has been refining and improving its process for creating micropacked columns. Rosemount Analytical micro-packed columns offer a superior combination of the features found in both capillary and conventional packed columns.

The result is improved chromatography with extended column life (several years in most applications without measurable degradation or bleed). Rosemount Analytical micro-packed columns produce sharper peaks for improved component separation, short analysis time and very low carrier-gas consumption.

MON2000 PC WORKSTATION
The Model 500 Process Gas Chromatograph is designed to operate unattended. If however, adjustments are needed; our exclusive MON2000 software allows complete control of you gas chromatographs – either locally or remotely. From within MON2000, a user can:
  • Review and modify analytical settings
  • Upload and display multiple chromatograms on the screen for comparison
  • Upload and trend any of the measured results
  • Export data for use in other 3rd party applications
  • Overlay multiple chromatograms for troubleshooting and calibration
  • Check original calibration against last calibration

The MON2000 PC Workstation Software is Windows™ - based software to make analyzer configuration, maintenance and data collection easy. With intuitive drop-down menus and fill-in-the-blank tables, even new users can quickly navigate through the software.

The MON2000 software can display both current and multiple archived chromatograms on the screen streamlining the time needed to performance routine analyzer maintenance.

MON2000 also has a number of tools built in that help users manage their analyzers such as:
  • Automatic recording of alarms in a log file
  • Event logs that provide a continuous record of all operator changes with time and user name stored
  • Maintenance log scratch pad for keeping track of maintenance or testing done
Data collected from the gas chromatographs can be stored and displayed in a wide range of options such as trend lines on the screen and logs automatically documenting all changes made to the gas chromatograph. Data can also be exported in formats compatible with most third-party Windows™ applications.

ANALYZER NETWORKING AND DATA COMMUNICATION
Emerson’s Rosemount Analytical gas chromatographs can be configured in a number of networking and data communication schemes to meet most process communication requirements.

Options include Ethernet networks as well as multi-drop RS-485 networks. It is even possible to set up automatic polling for data collection over phone lines if desired.

Data communication options to the plant control system include simple analog and discrete signals as well as Modbus serial links. To preserve the integrity of the analysis data, all Model 500 gas chromatographs are capable of storing up to 99 days of analysis data in the event of loss of communication to the plant control system.

All Rosemount Analytical process gas chromatographs are designed to operate unattended. Occasionally, adjustments to the analyzers’ analytical method or a review of possible alarms may be needed. Using our exclusive MON2000 software loaded on either a PC or laptop running Windows™, you’ll have complete control of your gas chromatographs – either locally or remotely.

NETWORKING FLEXIBILITY
Whether you want to network gas chromatographs throughout the plant or simply link a single gas chromatograph to the DCS system, the Model 1000 can be configured to handle most any scenario:
  • Choice of Ethernet or RS-485 network
  • Can use same network to connect Model 700, Model 500 and Model 1000 gas chromatographs
  • Able to connect multiple PC workstations using MON2000
  • Connectivity to plant control systems using industry standard protocols such as Modbus and OPC

SECURE MODBUS CONNECTIVITY
For process gas chromatographs, Modbus continues to be the preferred choice to connect a gas chromatograph network to the plant control system. The design of the Rosemount Analytical Modbus avoids the use of central interface cards or computers that can act as a single point of failure in the Modbus link. Instead, the plant DCS system can “talk” directly to each gas chromatograph to gather the data needed. Furthermore, the register and coil addresses can be easy customized to meet the specific data structure of the DCS. There is also a program built into the MON2000 workstation to test the Modbus link to the DCS if troubleshooting should be needed.

ENVIRONMENTAL CHAMBER TESTING
Emerson Process Management provides the most thorough gas chromatograph testing in the world. Each Model 500 gas chromatograph must operate to specification in our walk-in environmental test chambers cycling between 0°F and 130°F for 24 hours minimum. This is all part of our commitment to provide process gas chromatographs that are capable of providing reliable measurements in the field.

CUSTOM ENGINEERED SAMPLE SYSTEMS
Any gas chromatograph can only be as good as the quality of the sample it measures. So every sample system for Rosemount Analytical gas chromatographs is custom engineered for the specific requirements of the application.

Common features include:
  • Heated and open panel designs
  • All components rated for the area classification
  • Automatic calibration / validation available as an option
  • Variety of sample probes to extract a reliable and stable sample from the process
A complete on-line analytical solution is more than just the analyzer. Sample conditioning systems to prepare the sample for analysis, communication links to the plant control computer, and packaging of the analytical equipment into a cabinet or shelter all play an important role.

Emerson has decades of experience providing complete turnkey solutions ranging from simple single-analyzer cabinets up to large integrated shelters with multiple types of analyzers. The key to successful system integration begins at the proposal stage where Rosemount Analytical develops a custom engineer solution. This is followed with experienced project management during the system fabrication and on to installation and training once the system is delivered to the field.
