Improving Mass Spectrometry for Process Monitoring Possible instrumental methods to improve quantitative measurements using quadrupole mass spectrometry are discussed. Others have previously been reported that zone III has enabled the resolution of components CO and N2. These produce identical peaks at mass 28 using a zone I spectrometer.

Miniature Ion Source for RGA The ion source is one of the three main components of a Quadrupole Mass Spectrometer (QMS), and it is responsible for ionizing neutral atoms or molecules to create mainly singly charged positive ions. This is achieved using Electron Impact (EI) Ionisation whereby a current is applied to a tungsten or ...

The Benefits of High-K for Polymer TFTs High-K dielectric materials are now considered as alternative gate dielectrics to silicon diode (SiO2) mainly due to their high value of dielectric constant K. The high K value can reduce the threshold voltage and the supply voltage thus resulting in lower power consumption. The switching speed of a ...

Multivariate Analysis of QMS data from Natural gas Mud Gas Analysis (MGA) gives both short and intermediate term benefits in exploration and production. Quadrupole Mass Spectrometry provides an inexpensive measurement option against unforeseen drilling problems. Downhole collection and MGA is a key measurement goal since (i) this avoids atmospheric contamination ...
