Mass spectrometer systems can be divided into a variety of technological categories. Quadrupole mass spectrometers are the most widespread systems because they perform very well. They also stand out due to their compact and robust construction.
For mass separation, quadrupole systems use a high-frequency alternating electrical field. A Faraday cup and a secondary electron multiplier (SEM, Channeltron) serve as detectors.
Quadrupole mass spectrometers allow fast measurements within milliseconds and offer a high dynamic range from the ppb to the percentage level. These systems can be optimised for specific application purposes, therefore providing an attractive price/performance ratio.
InProcess Instruments has specialized in a modular concept of quadrupole mass spectrometers for online gas analysis. We offer a wide variety of individual equipment combinations that are optimised for the customer's needs and applications.
