The present invention relates to an improved analytical method and apparatus
therefor, in particular to a method and apparatus for continuous titration in which
at least one parameter of at least one compound in a test mixture may be monitored
as the composition of the mixture is continuously varied. The method comprises
the steps of continuously mixing at least two component fluid streams to form a
test mixture stream and passing the test mixture stream through a spectrophotometric
detection zone, with the volume to volume ratio of at least two of the component
streams forming the test mixture stream continuously and linearly varied with time
by alteration of the relative proportions of the component streams forming the
test mixture, while the total volume of the test mixture stream remains constant.
