Any other information on results incl. tables

- DIP/MS

A small amount of phosphorous acid put in the DIP probe and run with the above mentionned program clearly shows the formation of phosphine. The three solid dequest grades were run under simiilar conditions and the ion 34 is onl.y seen as a background for DTPMP-Mg.

- ATD/GC/MS

The formation of phosphine was observed

- Drager tube

The formation of phosphine was observed without ambiguity.

Applicant's summary and conclusion

Conclusions:
The test substance was observed to generate phosphine when heated to a high temperature of ~250°C.
