I have developed software for a wide range of mass spectrometer systems. I spent ten years working for VG Instruments (then Fisons Instruments) and three years in Japan looking after software support and localisation. I worked mainly on software for inorganic and elemental analysis using TIMS, Stable Isotope, Quadrupole ICP-MS and Sector ICP-MS.
More recently I work as a independent consultant to scientific instrument manufacturers developing bespoke software for data analysis, instrument control and hardware interfacing. I have done a fair amount of work enhancing a package of MALDI/TOF software and more recently on Laser Ablation data analysis for ICP-MS.
Here are several independent resources on the Internet of interest to MS
Mike Cheatham's ICMPS, XRF and TIMS listservers hosted by Syracuse University
Base Peak Mass Spectrometry resources hosted by Wiley
SIMS annual workshop
A valuable listserver for trace inorganic analysis by ICP (MS & AES) PLASMACHEM-L on the email@example.com
If you have a requirement for additional software development resource or consultancy on data analysis and instrument control please drop me a line.
