High temperature combustion total organic carbon analyzer

TOC-800E High temperature combustion total organic carbon analyzer

Product introduction

The TOC-800E total organic carbon analyzer uses the high-temperature catalytic oxidation-NDIR detection principle to measure the total organic carbon concentration in water samples. It can detect water samples with TOC concentrations from 0.050ppm to 35000.0ppm. It has high sensitivity, accuracy and good stability.

TOC-800E total organic carbon analyzer is an instrument with simple structure. The main components are installed on the host computer. Before measurement, the instrument needs to connect the gas line and prepare reagents. The instrument is controlled by special software installed on an embedded microcomputer or an external computer to perform data processing such as measurement, calibration, and printing.

Application

• Tap water, surface water, river, lake water
• Domestic sewage, industrial wastewater
• Chemical water (cleaning water, cooling water, recycled water, etc.)
• Laboratory research

Working principle

The sample is fully burned and decomposed into carbon dioxide and water by the high-performance oxidation catalyst in the combustion furnace. The water vapor is removed after being cooled by the condenser. The carbon dioxide is measured by a non-dispersive infrared detector (NDIR) to determine the total organic carbon in the sample. The content measured; the inorganic carbon in the sample is decomposed into carbon dioxide and water by an acid reagent, and the water vapor is removed after being cooled by a condenser, and the carbon dioxide is measured with a non-dispersive infrared detector (NDIR), thereby determining the content of the total inorganic carbon TIC in the sample: Total organic carbon TOC=TC-TIC.

Features

1. High-resolution 10.4-inch touch screen, humanized interface, simple and convenient operation
2. Three-tube electronic condensation and dehydration technology ensures the dehydration efficiency of the entire system
3. Highly reflective gold-plated gas chamber, highly concentrated infrared light source and highly sensitive infrared detector ensure excellent NDIR performance; measuring ppb level data has sufficient sensitivity and accuracy
4. The detection curve is visible in real time, more intuitive
5. Real-time self-monitoring of temperature, pressure, and flow at multiple locations
6. The furnace heating adopts multiple protections. Overheating can automatically cut off the heating to improve product safety performance.
7. 64G hardware memory can store massive data for a long time and make it easy to query, and can query by time period
8. With password protection function

Technical advantages

1. The maximum temperature of the combustion furnace can reach 1300℃, which is much higher than 680℃, which greatly increases the oxidation efficiency, meets the detection requirements of almost all substances, and improves the detection accuracy and stability.
2. Different catalysts (such as CeO, Pt, CuO) and different temperatures can be selected according to the detection requirements of the sample, providing a full range of experimental conditions and making the detection more flexible.
3. Automatic injection of liquid samples saves manpower and time; the precision electromagnetic metering pump ensures the accuracy and stability of the injection volume, the continuous and uniform speed of injection, and avoids the fluctuation of test results due to individual operating differences; At the same time, the non-manual injection sampling method can reduce the contact between the human body and liquid, avoid human body injury, and improve safety.
4. The inorganic carbon reaction cell is designed with a heating device, which eliminates the tailing of sample peaks and shortens the sample measurement time.
5. A solid sampler can be configured to inject solid samples (soil, sludge, etc.) by boat, with a wide range of applications.
6. An automatic sampler is optional to achieve unattended operation, saving manpower and time.
