Hiden Analytical Ltd.Request Info
Hiden Analytical Ltd.’s Transient mass spectrometer system is designed for the analysis of fast transient gas events at pressures near atmosphere. The compact benchtop system is based on the proprietary HPR-20 QIC series gas analyzers and features a fast response capillary inlet and the HAL/3F PIC mass spectrometer with a pulse ion-counting detector. The combination enables inlet system response times of <150 ms and measurement speeds of up to 500 data points per second over a seven-decade dynamic range. The system monitors species with molecular weights to 300 atomic mass units, with higher mass ranges available. The MASsoft control and data acquisition software provides integral calibration routines and user-programmable template files for automatic analysis. Applications include pulsed gas experiments for catalyst characterization, surface reaction and reduction studies, respiratory analysis and process control.

1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
mass spectrometer
A device used to measure the masses and relative concentrations of atoms and molecules. It utilizes the Lorentz force generated by external magnetic field on a moving charged particle, in which the particles are deflected by the magnetic field according to their masses. Once deflected, the particles are detected and recorded electrically to provide a mass spectrum of the input beam of ions. 
process control
The collection and analysis of data relevant to monitoring the rate and quality of industrial production, either continuously or in batches. Corrections can be made manually or automatically, via a feedback control loop.
A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
