Modern titrators can be simply classified as one of two types: potentiometric and Karl Fischer, with the latter available in both coulometric and volumetric versions. While titration may be considered a basic analytical method, modern titrators are far from simplistic. Many titrators offer a variety of automation options and can perform titrations with great accuracy with minimal operator intervention. According to this year’s survey results, over 82 percent of survey respondents use automated titration in their labs, with fully half of respondents also using an autosampler.
