The following projects require the development and validation of standardized measurement methods for
ozone precursors using the following techniques:
- Automatic pumped sampling, pre-concentration and on-line gas chromatography with flame
ionisation detector (FID) and/or mass spectrometer detector (MSD);
- Manual or automatic canister sampling followed by off-line gas chromatography with FID and/or MSD;
- Manual or automatic pumped sampling followed by off-line thermal desorption and gas chromatography with FID and/or MSD;
- Diffusive sampling followed by thermal desorption by off-line gas chromatography with FID and/or MSD;
- Manual or automatic pumped sampling of formaldehyde on dinitrophenylhydrazine (DNPH) followe by off-line high-performance liquid chromatography (HPLC) / ultraviolet (UV) detection;
- Diffusive sampling of formaldehyde on DNPH followed by off-line HPLC/UV detection.
For these projects, a literature survey and consultation providing the basis for the
standardization for all requested methods will be contracted. These tasks are subject to this call for tender
