Complexometric titration with EDTA is the usual winery procedure for determining calcium (4, 6, 22, 113), but atomic absorption spectrophotometry (51,53,112) and flame photometry and a rapid micro method based on oxalate precipitation (114) have been used successfully.

Rao et al. (1993) present a modification of the usual CS2 evolution method (which measures CS2 by spectrophotometry) with a method that converts maneb to a manganese-PAN complex that is extracted in isobutyl methyl ketone (MIBK) the complex then absorbs at 550 nm and can be measured from 0.37 to 3.75 micrograms/mL. Their method determines micro-quantities of maneb in commercial formulations, synthetic mixtures, grain, and in the presence of various other dithiocarbamates. The authors note that this method is particularly selective since other pesticides like ziram, zineb, and ferbam which usually interfere in other methods did not interfere under their experimental conditions.
