Results
The sample solution concentrations and masses of transferred test item are shown in Table 1. The individual and mean experimental vapor pressure results are shown in Table 2.
Overall result: vapour pressure at 20.0 °C (293 K) equals 5.2 x 10-8 Pa
vapour pressure at 25.0 °C (298 K) equals 1.4 x 10-7 Pa
Validation
The linearity of the detector response with respect to concentration was assessed over the nominal concentration range of 0.2 to 10 mg/L. This was satisfactory with a correlation coefficient of 1.000 being obtained.
To confirm specificity of the analytical method, aliquots of a standard solution and a sample solution were analysed using a diode array detector (DAD) to record the ultraviolet spectrum of the analyte peak used for quantification. The spectrum generated was consistent between the standard and sample solution
Discussion
Calculation of the final reported vapor pressure values have been performed from unrounded values, whereas individual intermediate values, such as areas, concentrations and masses presented in the tables have been rounded for the purpose of report generation. Therefore, minor discrepancies may be obtained if attempting to repeat the calculation process using reported data values presented to a reduced number of significant figures.
The absence of any detectable concentration of test item in any trap 2 (the second trap in series for each flow rate) on analysis indicated complete condensation of the test item in the trap 1.
