For those that are interested, here is the spreadsheet used in the ASMS 2016 short course. Thank Dr. Bill Siems if you see him.
Open-Source, Modular Approaches to Ion Mobility Spectrometry
Outside of an ionization source and a Faraday plate, a drift tube IMS system is fundamentally comprised of 5 primary components: Reaction/Drift Cell Ion Gate Gate Pulsing Electronics Current to Voltage Converter Data Acquisition System (DAQ) Within the IMS research community hardware and DAQ solutions are often custom and rarely … Continue reading
Fourier Transform Ion Mobility-Ion Trap Mass Spectrometry
We are pleased to report the publication of our work outlining the effective coupling of a drift tube IMS system with an ion trap mass spectrometer. Compared to previous implementations (see our 2005 publication) we have dramatically improved the IMS duty cycle by encoding the mobility information in the frequency … Continue reading

In the Spring Semester of 2015, Dr. Clowers was recognized within the College of Arts and Sciences at Washington State University for Early Career Achievement. The College of Arts and Sciences celebrated achievements in teaching, research, and mentoring at its third annual Appreciation and Recognition Social on April 22, 2015. … Continue reading
Live from Fulmer Hall: Waters G2
We are pleased to announce the unpacking and, more importantly, the successful pump down of the G2. Combined with a new UPLC unit we anticipate this instrument playing a large role in future metabolomics work in our laboratory. Kudos to Justin Chang from Waters for executing the pump down sequence … Continue reading
Waters G2 at WSU
Unboxing to commence in t-minus 6 days and counting…
IMS – Ion Trap Equipped with UV Photofragmentation
In early 2015 the research group is pleased to bring the next generation ion mobility-ion trap system online. This system is equipped with two ion gates which allows the speed of the IMS to be effectively coupled to the slow scan speeds of traditional ion trapping experiments. Though not … Continue reading
Savitzky-Golay Smoothing GUI
In an effort to create a set of simple tools that are useful for data processing and realtime analysis of data we’ve been exploring a range of tools. Granted there are a number of canned solutions in existence (e.g. National Instruments), however, to avoid the long-term challenges of compatibility we … Continue reading
Venn Diagram Widgets
Generally, it is recommended to avoid qualitative measures when quantitative solutions exist. However, if the genuine need arises here are a list of useful Venn diagram widgets that may be found online: Quite Powerful: http://bioinformatics.psb.ugent.be/webtools/Venn/ Simple Solution: http://www.bioinformatics.lu/venn.php Downloadable: http://pcarvalho.com/patternlab/vennDiagram.shtml
3D Printing CTC PAL Autosampler Trays
Recently, we brought two CTC PAL systems on-line in the group and in an effort to save a little bit of money* and explore the utility of 3D printing we engaged the engineering department at WSU to print out a sample trays that was compatible with the PAL system. Granted … Continue reading
