I suggest researching the JAOAC for methodology and build a gravimetric calibration curve and determine limit of detection.  It might not have anything helpful but there's also "inorganic spot tests" by Fiegl & Anger. 

Just some ideas.

Hi Jim,


Do you or anyone else in the discussion group know of a simple  wet, chemical qualitative method for detecting the presence of methanol in an aqueous solution?  The exact concentration is not necessary but a relative/comparative concentration would be nice.  In particular, I would like to monitor the methanol concentration as aspartame decomposes over time in soft drinks, suitable for an undergraduate laboratory experiment.  I suppose FDA must have protocol for this, but their method may involve the use of a GC-FID.
