In modern catalyst research, process development, and pilot-scale testing, evaluating fast-changing gas compositions requires analytical instrumentation that is both remarkably swift and structurally resilient. Laboratories often operate with limited bench space while demanding continuous, unattended analysis over extended periods. To directly address these demanding parameters, the GAS Catalysis Reaction Gas Analyser utilizes up to four parallel analytical channels working simultaneously to separate and quantify permanent gases, hydrocarbons, aromatics, oxygenates, and trace sulfur species without interference.
The instrument features a programmable column oven powered by a low-mass nickel wire, providing incredibly rapid resistive heating rates of up to 500 °C/min. This unique architecture drastically cuts typical runtimes to under two minutes, with no additional conditioning required between runs. Furthermore, handling samples from low-pressure or small-volume pilot reactors is effortlessly managed via an advanced vacuum sampling capability that draws loops down to 4 mbar, requiring only 1 to 2 mL of actual sample gas. By combining highly durable diaphragm process valves with automated stream selection for monitoring multiple reactors, this system delivers an optimal return on investment through extreme flexibility and low operational costs.
