Low Mass High Resolution

The Extrel Low Molecular Weight Gas Analysis System is a High Sensitivity, High Resolution system that has been designed for applications such as High Purity Leak Calibration, Isotope Ratio work or Helium and Deuterium  separation  It is a rugged, high stability  gas analysis system with the versatility both R & D and industrial applications. It has a true analytical data system, and  detection limits of  100% to 10 ppb.

The Extrel Gas Analyzer consists of a stand- alone quadrupole mass spectrometer system including pumps, chamber, atmospheric pressure sampling flow-by tee inlet, closed source ionizer, and a high transmission 19 mm quadrupole, with a standard mass range of  1 to 60 amu. 

The Low Molecular Weight Gas Analysis System has a wide range of options to allow it to used in almost any application.  These include special pumping packages for use with corrosive, toxic and  high value specialty gases. Other options include heated components for use with condensables, valve control and multiport valves for monitoring several gas streams, and special packaging.

Lamp Analyzer

Custom batch analyzer that provides gaseous composition of lamp fill gases. Some of the types of lamps the Questor Lamp Analyzer has successfully monitored include incandescent, fluorescent, halogen, parabolic as well as several custom lamps. Request information. Specifications

Blister Analyzer

Custom batch analyzer that provided gaseous composition of encapsulated gas "blisters" in glass production. The Questor Blister Analyzer is capable of analyzing glass samples in various forms including capillaries, core-drilled disks, and LCD flat glass disks. Request Information   Specifications

APIMS - Atmospheric Pressure Ionization Mass Spectrometer

• Low Parts Per Trillion Detection Limits • Stable Response • 1 to 300 amu Mass Range, Other Mass Ranges Available • Positive and Negative Ion Detection • Monitor up to 20 Masses • Optional Gas Dilution System

Our current APIMS system is a third generation instrument with a wide range of options that allow you to customize it to your application.

The flexibility and precision of our systems permits you to focus the instrument on the specific gases of your application. It also allows you to go beyond simple process monitoring to do process trouble shooting and fundamental research.

The APIMS system uses our proven, reliable DC Corona Discharge source. The DC Corona Discharge Source is a chemical, or soft ionization source that is ideal for monitoring molecules. This source has an additional Electron Impact (EI) filament for Residual Gas Analysis and system trouble shooting.

We use a single, high signal transmission, 19 mm (3/4 inch) rod quadrupole mass filter with and RF only pre-filter to provide the highest possible sensitivity for most applications. We can configure systems with a triple quadrupole mass filter to provide APIMS / MS capabilities for Research and Extremely demanding applications

The Extrel CMS APIMS system uses the flexible and easy to use Merlin Automation Data System Controller and Software Package for system operation and data collection. This is a Windows 2000/XP based package that can be run from a PC. This allows for high speed data acquisition, powerful data processing and Library Search.
