Name:
General Jimenez Chambers Vapor Wall Loss Characterization

Instrument:
Nitrate-adduct Chemical Ionization Mass Spectrometer

Chamber:
1-White (1W)

Temperature (°C):
20

Relative humidity (%):
0

Volatile compound name or class:
3. Multifunctional compounds generated in-situ.

Volatile compound source:

In-situ formation via reaction

Date of characterization experiment:
2021-11-05

Months since calibration:
0

Wall loss experiment description:
Compounds generated in-situ are produced through a 10 second photo-oxidation of commercially available precursors (1-alkanols), where photo-oxidation start and stop times are precisely controlled by photolysis of CH3ONO (methyl nitrite) in the presence of NO (nitric oxide) using 350 nm blacklights. Lower volatility, multifunctional compounds that are generated are monitored in real time by a NO3- CIMS at 1Hz. No fan should be used after lights turned on/off and the chamber is particle and should produce little aerosol during the oxidation.

Vapor loss calculation method:
The time series of the compounds are fitted and modeled using a kinetic solver (KinSim) which runs within Igor Pro. The production, transfer to chamber walls and evaporation from walls are modeled.

Parameterization developed:
Yes

Parameterization description:
A first order rate of transfer from gas-phase to the chamber walls is calculated for the chamber and a compound-dependent saturation vapor concentration (C*) is computed.
