Need more approved terms (SampleExtractionMethod)

[Adafede]

Hi,

I am actually trying to add ReDu compliant metadata of previously uploaded MassIVE datasets.

I have samples that were extracted using acidic acetone (1% HCl), could this (or related controlled vocabulary) be added to the list of solvents?

Btw, it looks like the acidity (or basicity) is actually not taken into account within solvents. This might be problematic for many extraction protocols (alkaloids...)

Best,

@alan-jarmusch what do you think in representing these additional extractions?

[alan-jarmusch]

'acetone-hydrochloric acid (99:1)' will be added to "SampleExtractionMethod"
you are correct we do not capture pH information. The point you raise is correct and understood. Given the difficulty of measuring pH in organic solutions - I have defaulted to listed the composition as above (v/v unless otherwise stated)

Perfectly understandable, thanks a lot!
