Gas chromatographic determination of thiamine in meats, vegetables and cereals with a nitrogen-phosphorus detector.

A gas chromatograph with a nitrogen-phosphorus detector has been used to quantitate thiamine in a number of meats, vegetables and cereals. Thiamine concentrations found in the foods investigated are in the acceptable range of concentrations determined by spectrophotometric methods. For most foods, deviation from an experimental mean concentration of ten… (More)
