CW-700 total organic carbon analyzer TOC analyzer

Introduction

CW-700 total organic carbon analyzer could a following application:

Deion water samples like Injection water, purified water, etc

The pharmaceutical industry cleaning validation

Tap water, surface water

Chemical water (clean water, cooling water, recycled water, etc.)

For scientific research lab

Fundamentals

    Subtraction: The samples by UV persulfate decomposed sufficiently oxidized into carbon dioxide and water, the dehydration condensation of the carbon dioxide measured by non-dispersive infra-red detector (NDIR), total carbon in the sample to determine the content of the TC; agent via an acid decomposition of inorganic carbon in the sample carbon dioxide and water, dehydration condensation, with a non-dispersive infrared carbon dioxide detector (NDIR) measurement, the sample to determine the TIC of the total inorganic carbon content; TOC TOC=TC-TIC.

    Direct method: First through the acid reagent inorganic carbon in the sample is decomposed into carbon dioxide and water to remove total inorganic carbon TIC; through UV persulfate sample decomposition of organic carbon into carbon dioxide and water, dehydrated condensed carbon dioxide by non-dispersive infrared detector(NDIR) measurement to determine the total carbon content in the sample of TOC.
