Researchers studying the use of catalysts strive to better understand how they function and respond under different conditions. Tracking the inlet and outlet of the reactor helps the investigator develop an understanding of the catalytic reaction. The composition of the outlet stream provides information about the reaction, efficiency and selectivity of the catalyst. For that reason, scientists rely on Extrel laboratory gas analyzers for accurate and flexible analytical performance. The use of these systems also makes scale up to production analysis easier since our EXTREL™ MAX 300-RTG 2.0 Industrial Gas Analyzer is functionally similar but designed for pilot scale and full production environments.
Our VeraSpec™ MBx quadrupole mass spectrometer system is a 3-stage, discreetly pumped gas analysis system designed for sampling reactive and condensable gases. The MBx is designed with a heated inlet, easily changed first aperture and skimmer, and an isolation gate valve to allow inlet maintenance for applications, which have challenging sample conditions, such as pyrolysis. The carefully engineered inlet provides a supersonic expansion of the sample into the vacuum to maintain sample integrity. This ensures accurate analysis of analytes before they react or decompose. The VeraSpec MBx is an integral part of the High Throughput Analytical Pyrolysis (HTAP) system, which was developed in collaboration with the National Renewable Energy Laboratory (NREL), Arbor Gen, and Frontier Labs. The HTAP system is used to accelerate the search for new and improved biofuel sources and has shown improvement in the analysis of pyrolysis products.
Evolved Gas Analyzer
Equipped with a 2 m heated transfer line, an extensive compound library, and the ability to import a variety of external signals, the MAX300-EGA™ is optimized for interfacing with thermal analyzers and microreactors. The chemically inert capillary keeps the sample hot and under vacuum all the way from the furnace to the ionizer to prevent condensation and chemical interaction during transit. Data synchronization couldn’t be easier; the Questor® 5 software comes standard with the ability to receive external signals, like the Start-of-Heating signal from a TGA. Trend and manipulate data within Questor® 5 or simply export it for use on a different platform.
Simply select the gases to measure, or the mass range to scan, in the software and the MAX300-CAT™ is configured to monitor a new reaction or process.
MAX300-CAT Laboratory Gas Analyzer Applications
VeraSpec™ APIMS System
The VeraSpec APIMS System provides the ideal ionization techniques for pure gas analysis in one system. The system can be configured for both ionization techniques, eliminating the need for two mass spectrometers, and significantly reducing the overall expense. The base system utilizes either Extrel’s high-performance, closed-source EI ionizer, or the proven, reliable DC Corona Discharge API source. The DC Corona Discharge Source is a chemical or soft ionization source that is ideal for monitoring molecules in the ppb and ppt range. The EI system is taken from Extrel’s MAX300 industrial mass spectrometers and has the same proven performance available on those systems with detection limits in the low ppb range. The system utilizes a 19 mm trifilter quadrupole and is available in several mass ranges. The system is also offered in an MS/MS configuration, the VeraSpec Trace MS/ MS.
