Overview

Product name: Lotix toc analyzer Product model: Updated on May 31, 2023 Brand: Tekmar Production address: Lotix toc analyzer uses high-temperature combustion method to oxidize different forms of carbon in the sample into carbon dioxide, and uses a new non dispersive infrared detector (NDIR) for quantitative detection. TOC analyzer is widely used for the analysis and monitoring of organic pollutants in environmental water such as rivers, lakes, and reservoirs, water quality management of industrial wastewater and sewage treatment plants, research and analysis in fields such as environmental protection, universities, and scientific research, as well as pure water and recycling management in chemical, semiconductor, ultra pure water systems, nuclear power, and other fields.

Product Details

　　Instrument Introduction

The Lotix Total Organic Carbon Analyzer (TOC)/TOC analyzer uses high-temperature combustion method to oxidize different forms of carbon in the sample into carbon dioxide, and uses a new non dispersive infrared detector (NDIR) for quantitative detection. Widely used for analysis and monitoring of organic pollutants in environmental water such as rivers, lakes, and reservoirs, water quality management of industrial wastewater and sewage treatment plants, research and analysis in environmental protection, universities, scientific research, and other fields, as well as pure water and recycling management in chemical, semiconductor, ultra pure water systems, nuclear power, and other fields. Compliant with multiple domestic and international standards such as EPA 415.1/9060A, SM 5310B, ISO 8245, ASTM D2579, AOAC 973.47, HJ 501-2009, etc.

　　main features

　　1Simple design, short analysis time, and low daily operating costs;

2. Easy to maintain, all components such as heating furnaces and combustion tubes can be maintained within minutes;

3. Wide linear range, only one calibration curve is needed to meet the analysis requirements of different content ranges;

4. The software is easy to operate, and a marking can be set in less than 1 minute;

5. Adopting a designed high-sensitivity non dispersive infrared detector (NDIR);

6. Emergency samples can be added during the analysis process for optimal testing;

7. Meets multiple domestic standards such as HJ 501-2009 Determination of Total Organic Carbon in Water Quality by Combustion Oxidation Non Dispersive Infrared Absorption Method.

　　Two methods of measurement:

Direct measurement method: pre acidify the water sample, introduce nitrogen gas for aeration, remove various carbon dioxide generated by carbonate decomposition, and then inject it into the instrument for measurement. During the aeration process, the loss of volatile organic compounds can cause errors, so the measurement result is the carbon value of the organic compounds that cannot be blown out.

Subtraction method: Inject the same amount of water sample into a high-temperature furnace (900 ℃) and a low-temperature furnace (150 ℃), respectively. The organic carbon and inorganic carbon in the water sample will be converted into carbon dioxide, and the organic matter in the quartz tube of the low-temperature furnace cannot be decomposed and oxidized. The difference between total carbon (TC) and inorganic carbon (TC) measured in high and low temperature furnaces is called total organic carbon (TOC).
