✦ Synopsis

A procedure for tbe automated determmatron of sod and plant nitrogen from Neldahl digests has been proposed The contmuous flow system mvolved the use of a unique mxrodBtdlatlon unit followed by colounmetnc detection of the pure ammomum chlonde dlstdlate Optmnsatlon of the mdophenol reaction IS shown together wth a standard manual procedure for comparison Interference-free determmations may be camed out at a mmmmm of 30 samples he1 and the system has proved to be most relrable for routme analysis Keywords Contmuous flow, Mxrodwtdlatlon, Nitrogen
