| Abstract: | Summary A mathematical derivation of efficiency and resolution equations for use in conjunction with flame photometric detection of sulphur compounds is presented. These equations are similar to those for linear detection apart from the incorporation of the exponential response factor, n, in the denominator of the respective expressions for non-linear detection. The latter equations reduce to those usually recognised for linear detection if the value n=1 is substituted. Equating the column efficiency equations for linear and non-linear detection permits direct determination of the value of n. |
