| description | As part of the European ACTRIS project, the first large Quadrupole Aerosol
Chemical Speciation Monitor (Q-ACSM) intercomparison study was conducted in
the region of Paris for 3 weeks during the late-fall – early-winter
period (November–December 2013). The first week was dedicated to the tuning and
calibration of each instrument, whereas the second and third were dedicated
to side-by-side comparison in ambient conditions with co-located instruments
providing independent information on submicron aerosol optical, physical, and
chemical properties. Near real-time measurements of the major chemical
species (organic matter, sulfate, nitrate, ammonium, and chloride) in the
non-refractory submicron aerosols (NR-PM<sub>1</sub>) were obtained here from 13
Q-ACSM. The results show that these instruments can produce highly
comparable and robust measurements of the NR-PM<sub>1</sub> total mass and its
major components. Taking the median of the 13 Q-ACSM as a reference for this
study, strong correlations (<i>r</i><sup>2</sup> > 0.9) were observed
systematically for each individual Q-ACSM across all chemical families
except for chloride for which three Q-ACSMs showing weak correlations partly
due to the very low concentrations during the study. Reproducibility
expanded uncertainties of Q-ACSM concentration measurements were determined
using appropriate methodologies defined by the International Standard
Organization (ISO 17025, 1999) and were found to be 9, 15, 19, 28, and 36 %
for NR-PM<sub>1</sub>, nitrate, organic matter, sulfate, and ammonium, respectively.
However, discrepancies were observed in the relative concentrations of the
constituent mass fragments for each chemical component. In particular,
significant differences were observed for the organic fragment at
mass-to-charge ratio 44, which is a key parameter describing the oxidation
state of organic aerosol. Following this first major intercomparison
exercise of a large number of Q-ACSMs, detailed intercomparison results are
presented, along with a discussion of some recommendations about best
calibration practices, standardized data processing, and data treatment. |
