The flameless atomic absorption procedure for determination of minute amount of mercury has been adapted for measuring thiol-groups in native and denatured proteins. The excess of p-hydroxymercuribenzoate is removed by gel filtration after its reaction with the protein. The protein-p-hydroxymercurib
## Abstract The metal content (Cu, Fe, Ni, Pb) of Finnish margarines manufactured in 1978โ80 were investigated by the flameless atomic absorption spectrophotometry method. Copper, iron and nickel were digested by the dry ashing method whereas for lead both dry ashing and wet ashing were employed. T
Flameless atomic absorption spectrometry is a sensitive, rapid, selective and precise technique which is very attractive for the routine analysis of small liquid and solid samples. Little pretreatment of the samples is necessary, so that the risk of contamination is small. Recently, this technique h
