Results and discussion

Vapour pressure
Remarks on result:
not determinable
Remarks:
see explanation below

Any other information on results incl. tables

Four trials were conducted and five points were recorded for each trial except for the second trial where no exploitation was possible.

Log10(Vapour Pressure (Pa)) was plotted against reciprocal temperature but no linear relation was observed (correlation coefficient R² below 0.95). Therefore no value of vapour pressure was calculated at 20°C or 25°C.

Applicant's summary and conclusion

Conclusions:
In conclusion, no vapour pressure could be obtained for SODIUM CHONDROITIN SULFATE during this study.
