- Conclusions:
- The vapour pressure of D-8 was measured by a gas saturation method as described in the OECD Guideline 104. The vapour pressure of D-8 was less than 1.0E-05 Pa at 27 °C.
- Executive summary:
The vapour pressure of D-8 was measured using a gas saturation method as described in the OECD guideline 104. In this procedure, a stream of inert carrier gas is passed over the substance in such a way that it becomes saturated with its vapour. The amount of material transported by a known amount of carrier gas is measurable either by collection in a suitable trap or by an intrain analytical technique. This was then used to calculate the vapour pressure at a given temperature. According to this test method, the vapour pressure of D-8 was less than 1.0E-05 Pa at 27 °C.

Results and discussion:
The minimum quantifiable amount of D-8 was 0.5 ng, i.e. 210 of the integral peak area at AUFS. Taking account into interferences, the detection limit was set at 1 ng / 20 μL injection. This concentration makes the total quantity (W) of 25 ng in 0.5 mL of the final solution. If we use W = 25 x 10-9 g, V = 87.2 L (20.0 mL/min x 4360 min), T = 300 and M = 292.4, a minimum measurable limit of the vapour pressure is calculated as 2.4E-6 Pa.
The experimental results are summarized in Table 1. Each value is mean of duplicate measurements in HPLC for the same sample.
