SAM-1.0 Total Organic Carbon Analyzer 

Introduction
  SAM-1.0 Total Organic Carbon (TOC) Analyzer is the high-precision offline total organic carbon analysis instrument. The product uses the electrical conductivity difference detection technology,adopting the principle of ultraviolet catalytic oxidation, with high accuracy and short response time. The instrument completely conforms to the requirements of the national pharmacopoeia, and it can meet the offline testing requirements for the deionized water such as pharmaceutical water (injection water and purified water) and ultrapure water.

Operation Principle
Oxidation organism by UV lamp and convert organic stuff into carbon dioxide, which detection adopted by direct conductivity method. The total organic carbon is the difference of the total carbon (TC)concentration in samples tested after oxidation and not oxidation of the sample total inorganic carbon(TIC), namely: TOC = TC- (TIC).
