CO-CIMS
From Jimenez Group Wiki
This page documents the Colorado Front Range ToF-CIMS & Related Techniques Users Meetings, started in Feb. 2017.
Next Meetings
- Tentatively we are planning on 1/2 day meetings twice a year. Thus the next meetings will take place in June or July 2017 and on Feb. 2018. This may change depending on the interests of the participants.
1st Mtg: February 2017
- This meeting took place at CU on 15 Feb 2017.
- The schedule is here
- Introduction
- High-Resolution Peak Fitting Issues
- Andy Neuman: Reasons for embracing negative peaks. I'll show examples of bias introduced by not allowing negative peaks, and discuss how to best measure compounds with mixing ratios that often approach zero
- Ryan Fulgham: Harald's tools for peak fitting by functional group (no presentation)
- Harald Stark: Data analysis Q&A (no presentation)
- Background signals and related topics
- Matt Coggon: Post-Tofware Data Processing - Background Correction Procedures
- Demetrios Pagonis: Tubing delay analysis
- Ellie Browne: discussion on reducing backgrounds (no presentation)
- Calibrations
- Jordan Krechmer: CIMS calibration: transmission curve and voltage scanning
- Bin Yuan: Liquid Calibration Unit (LCU)
- Ion Chemistry, IMR and related topics
- Andy Neuman: Possible matrix effects with iodide ion chemistry. I'll show how the response to calibrations can depend on the background air composition.
- Michael Link: How competitive are the rates of thermally enhanced processes and wall to gas partitioning with particle to gas partitioning using the "Aerosol CIMS" measurement technique?
- Patrick Veres: IMR redesign tests and results
- Applications
- Carsten Warneke: Intercomparison of I-CIMS and H3O+CIMS during FIREX Firelab
- Harald Stark: Ambient amine measurements using protonated ethanol CIMS
- Kanako Sekimoto: PMF analysis of Firelab data
- Aroob Abdelhamid + Jennifer Berry: Applications of the APi-ToF
- Patrick Veres: HCl and ClNO2 observations in Boulder via TOF CIMS and Picarro CRD
