Total Organic Carbon Analyzer MSTA1.0SWISS Offline

Introduction: The MSTA1.0SWISS Total Organic Carbon (TOC) Analyzer is a high-precision offline analysis instrument developed by Beijing Neuronbc. This instrument utilizes electrical conductivity difference detection technology and the principle of ultraviolet (UV) catalytic oxidation, delivering high accuracy with a short response time. The MSTA1.0SWISS fully complies with national pharmacopoeia standards, making it suitable for offline testing of deionized water, including pharmaceutical-grade water such as injection water, purified water, and ultrapure water.

Operation Principle: The analyzer works by oxidizing organic compounds in the sample using a UV lamp, converting them into carbon dioxide. The carbon dioxide is then detected using the direct conductivity method. The total organic carbon (TOC) value is calculated as the difference between the total carbon (TC) concentration of the sample post-oxidation and the total inorganic carbon (TIC) concentration of the sample before oxidation:

TOC = TC - TIC
