English Abstract This report deals with the operationalization of a
Perkin Elmer Zeeman 4100 ZL instrument for the determination of trace

instrumental parameters. Performance characteristics were established and
compared with the specifications supplied. The instrument met the suppliers
specifications with respect to sensitivity, detection limits and precision.
A comparative investigation with the formerly used equipment showed no
