1. With the opacimeter operating normally, the reading on the linear scale of opacity is N and that of the mean gas temperature expressed in Kelvin degrees is T.
2. Maintaining, for at least 12 hours, over a temperature range of ± 1 K around a standard temperature and at a standard pressure, all of the following: a. A "resolution" over their full scale of 0,1 μm or less (better); and
3. Therefore, a CO2 span gas having a concentration of 80 to 100 per cent of full scale of the maximum operating range used during testing must be bubbled through water at room temperature and the analyser response recorded.
4. With the known length Lo filled with the same test gas, the reading on the linear scale of opacity is No and that of the mean gas temperature expressed in Kelvin degrees is To.
5. Therefore, a CO2 span gas having a concentration of 80 to 100 per cent of full scale of the maximum operating range used during testing shall be bubbled through water at room temperature and the analyzer response recorded.
6. A NO span gas having a concentration of 80 to 100 per cent of full scale of the normal operating range must be passed through the (H)CLD and the NO value recorded as D. The NO span gas must then be bubbled through water at room temperature and passed through the (H)CLD and the NO value recorded as C. The analyser's absolute operating pressure and the water temperature must be determined and recorded as E and F, respectively.
7. A NO span gas having a concentration of 80 to 100 % of full scale to the normal operating range shall be passed through the (H)CLD and the NO value recorded as D. The NO gas shall be bubbled through water at room temperature and passed through the (H)CLD and NO value recorded as C. The water temperature shall be determined and recorded as F. The mixture's saturation vapour pressure that corresponds to the bubbler water temperature (F) shall be determined and recorded as G. The water vapour concentration (in %) of the mixture shall be calculated as follows:’;
8. A NO span gas having a concentration of 80 per cent to 100 per cent of full scale of the normal operating range shall be passed through the (H) CLD and the NO value recorded as D. The NO span gas shall then be bubbled through water at room temperature and passed through the (H) CLD and the NO value recorded as C. The water temperature shall be determined and recorded as F. The mixture's saturation vapour pressure that corresponds to the bubbler water temperature (F) shall be determined and recorded as G.
9. Pipette a measured standard volume (15 µl is appropriate for 6 mm window diameter – scale up volume for larger windows) of the resuspended pellet and each dilution on a row of windows. The second row can be used as duplicate or for a second sample as presented in Figure 2. 5.2. Dry the droplets at ambient temperature or by warming to temperatures of 40 to 45 °C.
10. A NO span gas having a concentration of 80 to 100 per cent of full scale of the normal operating range must be passed through the (H)CLD and the NO value recorded as D. The NO span gas must then be bubbled through water at room temperature and passed through the (H)CLD and the NO value recorded as C. The analyser's absolute operating pressure and the water temperature must be determined and recorded as E and F, respectively. The mixture's saturation vapour pressure that corresponds to the bubbler water temperature F must be determined and recorded as G. The water vapour concentration (H, in %) of the mixture must be calculated as follows:
