| Abstract: | Direct analysis of Suspended solids by AAS is still in the stage of development. In thispaper direct analysis of trace Cu in suspended particle of vegetables by flameless AAS hasbeen described. Working parameters, including the size of suspended particles, homogeneity ofsampling, heating control program for atomization etc. have been optimized. |
