Trace Analysis — Challenges and Problems

Abstract

Analytical procedures and techniques employed to determine trace components are objects of growing interest to analysts. The determination of those components in samples of different matrix composition is becoming ever more common. Hence, attention should be paid to problems involved in this type of activity. The article presents specific problems connected with trace analysis. The problems and solutions proposed are documented with data from the literature.
