Mass Spectrometers Gas Analyzers

Unmatched Mass Spec Technology 

For Lab, Research & High Purity Applications Requiring Real-Time, Continuous Monitoring

Our Extrel real-time quadrupole mass spectrometers are built for the demands of the gas and ion analysis for industrial and high purity process control, environmental monitoring, and cutting-edge semiconductor and laboratory research.  Our mass spectrometers offer high sensitivity and a wide dynamic measurement range (ppb to %) for full, speciated composition.  Our fast and powerful, quadrupole mass spectrometer performs precision quantitative analysis on every component in a gas or vapor mixture.  It can easily be fully automated for sampling of multiple gas channels.  For decades we have collaborated with research, academic, and industrial customers to deliver, design, integrate validate, and support these unique turnkey solutions.

We also provide turnkey Mass Spectrometer Systems built upon our Extrel quadrupole mass spectrometer technology.  Our Atmospheric Pressure Ionization Mass Spectrometry (APIMS) is widely accepted as a powerful tool for pure gas analysis, given its unique ability for real-time, multi-component measurement down to parts-per-trillion levels. Extrel, the trusted source for Mass Spectrometers since 1964, delivers optimal performance, reliability, and ease of use with its new VeraSpec APIMS, enabling real-time monitoring of the most critical impurities – trace oxygen, moisture, methane, carbon monoxide, carbon dioxide, ammonia and more – in a single instrument.  Developed for research, electronic gas, and semiconductor applications, it is the first Extrel APIMS system available that incorporates an integrated touch screen graphical user interface for point-of-use visual indicators in gas purity, offering increased operational efficiency. Extremely simple to use, the VeraSpec APIMS has an intuitive web-based interface that allows the user to operate it with ease, and can check instrument status, review data trends, and run detailed analysis with the click of a button. Maintenance is also reduced with the option of scheduled automated calibrations.

The fast-acquisition breath analysis configuration of the MAX300-LG was designed in collaboration with leaders in the field of respiratory research. 


The Extrel MAX300-BIO Bioreactor Gas Analyzer has been installed in major manufacturing stages within pharmaceutical industries. 


Pharmaceutical manufacturers are well aware of the industry statistics that at least 25% of time and energy can be saved by terminating the active pharmaceutical ingredient drying process at its true endpoint. However, actually determining the true endpoint has always been an obstacle. To avoid interrupting the process (traditional methods to determine the drying process involved sampling and analyzing the product in a lab) and possible contamination of an entire batch, many producers choose to overextend the drying process.   Today’s engineers can solve this problem by using our MAX300-RTG 2.0 Industrial Gas Analyzer or MAX300-LG Laboratory Gas Analyzer. The MAX300 monitors the atmosphere composition above the drying material. Because the headspace is in close relationship with the concentration of solvents in the material, the true drying process end point can be determined by analyzing the headspace vapors.  The Quadrupole Mass Spectrometer allows you the ability to view the concentration profiles of solvents over time, pinpointing the exact moment the drying is complete. 


Due to the large number of chemical solvents used in the drying process, Quadrupole Mass Spectrometry is the only viable and economical analytical technology for Solvent Recovery applications.  To achieve the flexibility of analysis and parts per billion detection (ppb) limits, the Extrel MAX300-RTG 2.0 Industrial Gas Analyzer is the system of choice.  This online Quadrupole Mass Spectrometer system is capable of fast and flexible analysis of an unlimited number of compounds in a single analytical method. The selection and tuning of analysis masses is achieved through software, not hardware. Therefore, a pharmaceutical plant’s solvent recovery process can be streamlined with no idle time between batches. Additionally, this same system is capable of analyzing the final gas exhausted to the atmosphere to monitor plant compliance with environmental regulations.


Thermogravimetric analysis (TGA) is a powerful approach to the study of the thermal behavior of solid and liquid samples.  The interface of TGA with a quadrupole mass spectrometer allows the researcher to characterize and quantify the compounds in the off gas in real-time along with each mass loss.  Our MAX300-EGA comes equipped to import a Start-of-Heating signal from the TGA for easy data synchronization and features a chemically inert transfer line specially designed keep the sample hot and under vacuum all the way to the ionizer, to guard against condensation or chemical interaction.
