ABSTRACT:
An analyzer system for improving quality of a reaction product, wherein a liquid sample must be maintained at an elevated temperature to prevent precipitation of titratable species, comprises a heated sample and dilution section, an autotitrator and a programmable controller. In operation a liquid sample to be analyzed is withdrawn from a reactor and maintained at reactor temperature while being diluted. The diluted sample is then cooled and passed to an autotitrator for analysis. The analyzer system includes a programmable controller for automatic unattended dilution of successive samples.
