Miniature mass spectrometer systems based on a microengineered quadrupole filter.
Two miniature mass spectrometer systems based on a microengineered quadrupole mass filter have been developed. One of the instruments has a footprint of 27 cm x 20 cm and is intended for laboratory use when space is at a premium. The other is portable and intended for use in the field. It is battery powered, weighs 14.9 kg, and is housed in a rugged case. This is the first example of a portable...
متن کاملA quadrupole mass spectrometer for resolution of low mass isotopes.
The qualitative and quantitative identification of low mass isotopes in the mass range 1-6 u poses certain difficulties when attempting to achieve the required resolution with an instrument suitable for deployment within a process environment. Certain adjacent species present in the process sample (HT and D(2)) require a resolution greater than 930 to achieve an accurate measurement. We demonst...
متن کاملA microelectromechanical systems-enabled, miniature triple quadrupole mass spectrometer.
Miniaturized mass spectrometers are becoming increasingly capable, enabling the development of many novel field and laboratory applications. However, to date, triple quadrupole tandem mass spectrometers, the workhorses of quantitative analysis, have not been significantly reduced in size. Here, the basis of a field-deployable triple quadrupole is described. The key development is a highly minia...
متن کاملA novel high-capacity ion trap-quadrupole tandem mass spectrometer.
We describe a prototype tandem mass spectrometer that is designed to increase the efficiency of linked-scan analyses by >100-fold over conventional linked-scan instruments. The key element of the mass spectrometer is a novel high ion capacity ion trap, combined in tandem configuration with a quadrupole collision cell and a quadrupole mass analyzer (i.e. a TrapqQ configuration). This ion trap ca...
متن کاملMS1-Based Quantification Optimization on DIA Methods on a Quadrupole-Orbitrap Mass Spectrometer
The performance of DIA methods was influenced by the number of DIA windows, the scan resolution, the gradient length and the sampling of the chromatographic peaks. Additionally, the MS1 scan of the DIA method had an important influence on the performance. To optimize quantification on MS1, we evaluated the following conditions. We established a comprehensive spectral library by measuring tripli...
