Hiden Analytical introduce the new 'LoMASS' series quadrupole
mass spectrometers for precise determination of low molecular weight
species. Integration of the latest RF generation and 3-stage mass
filter technology enables operation at twice conventional frequency
rates providing major performance enhancement of both resolving power
and abundance sensitivity.
Hiden 'LoMASS' systems are available with mass range
options 1 amu to 20 amu and 1 amu to 50 amu, with choice of mass filter
pole diameters of 6mm, 9mm and 12mm to suit diverse applications.
Peak tail contribution from mass 4 - helium, deuterium - for instance
is less than 1 part-per-million (1 ppm) at adjacent masses. Mass peak
widths of just 0.1 amu at 5% peak height are routinely used together
with high detection sensitivity resulting from minimal transmission
reduction.
Typical stringent applications include low abundance
and impurity measurement, gas mixture quantification and precise isotope
ratio measurement. The small swept volume is a major asset for analysis
of minimal gas samples in applications such as geology and biomedicine.
The mass spectrometers are supplied fully vacuum integrated
with dedicated process interface and gas handling system or in basic
form for user process integration. The comprehensive software suite
features fast analysis rates, multichannel monitoring and wide, 10-decade
dynamic range.
