For use with the All-Star TOC Analyzer,Description: The Alkalinity/Direct method overcomes the limitations of traditional alkalinity testing and includes multi-endpoint determination via titration and colorimetric measurements..It avoids burettes,multi-standard,complicated and troublesome rotary valves to distribute metering volumes,etc..This method uses direct analysis of carbon dioxide and continuously measures the following values: The sample is fed into a reaction chamber and mixed with acid to reduce the pH to 2–3,at which point the above substances are converted into carbon dioxide.Measure carbon dioxide with non-dispersive infrared analyzer showing total base concentration and phenolphthalein alkalinity.
