Abstract

The photometric error contributions which the relative errors in determining both the cell pathlength ratio and the transmittance ratio minimum make towards the relative error in determining the relative stray radiant energy (SRE) levels in a ratio recording double-beam spectrophotometer were investigated, thus enabling optimum experimental conditions for SRE determination to be pre-selected.
