The bulk of the analytical data of a long period was used for estimation of RSD values of the CHNS analysis results obtained by EuroVector EA-3000 in the single-reactor mode. It is shown that the accident error level is conducted with the sample preparation procedure as well as with the properties of the certain analyzed samples. It is established that the experimental obtained CHNS analysis error levels significantly differ from those given in the technical specifications. In case of analysis of sample with the unknown composition the accidental errors of determination of each element are comparable with the standard sample ones. (C) 2011 Elsevier B.V.
