The Right Gas Chromatograph for the Job

By Bonnie Crossland, Product Marketing Manager – Gas Chromatographs, Emerson Automation Solutions

Balancing the right level of gas chromatograph (GC) performance and cost for individual applications and locations within a plant or installation is key for many operators. Increased pressure to optimize processes is driving an increased demand for accurate and timely composition analysis for use in process control and product quality assurance. To continue to meet these demands, Emerson’s Rosemount 1500XA process gas chromatograph adds new enhancements to provide faster compositional feedback and complete, high-resolution analysis, helping operators optimize product specifications and maximize throughput.

Rosemount™ 1500XA Process Gas Chromatograph

The Rosemount™ 1500XA process gas chromatograph is designed for refining, petrochemical, power, and environmental applications where selected components in gaseous or liquid streams must be precisely monitored on a continuous basis. The recent enhancements to the 1500XA enable parallel chromatography, offering oven capacity for up to eight chromatograph valves and four detectors, two of which can be flame detectors. Depending on the application, the 1500XA can include flame ionization or flame photometric detectors for measurement of compounds in the parts-per-billion ranges, or thermal conductivity detectors (TCD) capable of handling applications with parts-per-million measurement requirements.

The 1500XA, like the entire Emerson GC family, is characterized by ease-of-use, ruggedness, and reliability. Emerson is currently the only online GC supplier to offer a lifetime warranty on chromatograph valves. The valves are rated for more than five million operations before repair, which involves simply replacing the diaphragms and can be done easily on-site.

With its numerous valves and detectors, the 1500XA can take a complex analysis application and break it down into smaller, simpler analysis blocks. These blocks are then run in parallel, reducing analysis time and providing faster, easier maintenance and troubleshooting, as well as straightforward data analysis. A complex analysis that may have previously taken 20 minutes may now only take 10 minutes, allowing quicker response to process changes. The 1500XA’s concurrent analysis can be used to reduce the time between analyses by running them at offset times. This can increase the number of analyses within a set time period.

Emerson’s MON2020 software allows the 1500XA to operate completely unattended while making analyzer configuration, maintenance, and data collection easy, either locally or remotely. With intuitive dropdown menus and fill-in-the-blank tables, even new users can quickly navigate through the software.

Since many users are looking for cost-effective and reliable GC solutions, the 1500XA with parallel chromatography and concurrent analysis capabilities more than fulfills that need. When combined with the 370XA and 700XA gas chromatographs, the 1500XA rounds out the widest single selection of gas chromatographs on the market. This makes the Emerson GC family flexible, and reduces costs for integrators and users alike. Used in a wide range of industries, the Emerson GC line allows users to get precisely the performance they require in each location and application while maintaining the same easy-to-use interfaces, the unique software capabilities, and common maintenance requirements.
