✦ Synopsis

Flow injection microsampling dilution was combined with the zone penetration technique to produce an on-line dilution system capable of achieving 27,000 -fold dilutions in flame atomic absorption spectrometric determinations with a sampling frequency of (45 / \mathrm{h}) and a precision of better than (2 %) r.s.d. Readouts were made at the valleys between two sequentially injected micro-sample zones in the microliter range which penetrated each other. The method was applied to the determination of several grams per liter of magnesium in brine solutions without further dilutions. O 1994 Academic Press. Inc.
