The determination of low levels (< 1 %) of total carbon and nitrogen in soils, sediments and solid wastes is made fast using an automated elemental NCS analyzer (Carlo Erba NA-1500). The recoveries of total N obtained were similar with either the elemental analyzer or the Kjeldahl digestion method used. The recoveries and precision of the TC, TOC data were better and more predictable using the elemental analyzer than the wet digestion procedure used in this study. Acid pre-treatment prior TOC determinations using the NCS analyzer resulted in lower total N recoveries. The determination of S in the same materials using this analyzer is not recommended due to low recoveries and poor precision.
