ABSTRACT:
A method and apparatus are disclosed for monitoring a fluid stream with reference to one or more criteria. Successively a number of samples is drawn from the fluid stream that is at least one more than the number of analysis criteria. Each sampling step includes analyzing a portion of the fluid stream and preserving another portion. At intervals, on the ground of a selection criterion, one of the samples preserved is removed and a fresh sample is drawn, whereby--again--a portion of the fluid stream is analyzed and another portion preserved. The arrangement is such that, at all times, one sample is preserved that corresponds with an extreme value of each of the criteria of analysis.
