New high-end mass spectrometer! Fast, flexible and easy to operate. High measurement speed – up to 125 µs/amu Very fast measurements can be performed with the HiQuad® mass spectrometer. This example shows the mass spec response during respiration analysis. N2, O2 and CO2 were detected with a very fast cycle time. Wide dynamic range This scan shows a spectrum for air. In addition to the primary components, consisting of N2, O2, Ar and CO2 even minute concentrations of Xe are detected. The ion current at mass 136 is equivalent to a concentration of 7.8 ppb of Xe in air. And it is decades...

Overview of technologies Biased ionization chamber Field-axis technology Mass filter Ions Filament Biasing the ionization chamber results in an extremely low background signal. The electron-emitting filament is positively biased by 100 to 150 VDC relative to ground. This design prevents desorption of gas particles from the chamber walls, and thus the generation of an undesired background signal by electron stimulated desorption. One of the most important factors in the performance of a mass spectrometer is the transmission of the ions from the ion source into the mass filter. With the aid...

Quadera® – The HiQuad® software The Quadera® software serves as the interface between the mass spectrometer and the user. It excels as a result of its simple, intuitive operation. Repetitive measurement tasks can be automated by setting recipes and through the macro programming routines. ■ ■ ■ ■ Predefined recipes available, e.g. spectrum, trend, bar graph Easy-to-read mass spectrometer system presentation Automated measurement routines via the integral Visual Basic script editor Adaptation for special applications thanks to interchange with other programs Main window Tools, aids Status...

Weight / percent Temperature It is possible to display mass spectrometer data together with external data, such as temperature, sample weight, etc. The example in the illlustration shows coupling with a thermobalance. Different user-defined views of the same measurement can be displayed simultaneously. 1 Signal vs. time. 2 Bargraph scan of different masses. 7
