Controlled atmosphere discontinuous semiautomatic dispenser for carbon rod atomizer

Abstract

A semiautomatic dispenser for liquid solutions is described which makes possible a strict control of the atmosphere during the sampling operations. The dispenser was optimized with regard to the sampling mass reproducibility, by checking different capillary treatments. A typical relative standard deviation at l pl level of aqueous samples was 0.6 %.
