| Popis: |
The technique described is a sensitive analytical tool developed for the determination of trace elements. It combines paper chromatography, as the separation process with radiometric precipitation for quantitative determination. Procedures are described that are capable of determining submicrogram quantities of elements. Besides illustrating the use of radiosotopes in analytical chemistry, it is accurate, reproducible, inexpensive, and does not require a high degree of skill to perform the analysis. |
