Working principle of Karl Fischer furnace

After the sample is heated at high temperature and the moisture and other volatile substances are vaporized, the carrier gas is blown into the Karl Fischer moisture analyzer through a heatable sample outlet tube. The Karl Fischer moisture analyzer detects the moisture in the blown gas. Due to the reactivity of the Karl Fischer moisture analyzer with water, it only detects the moisture in the blown gas and does not produce any other interference. And connecting different instruments will further improve the detection accuracy, such as connecting the Coulomb method trace moisture analyzer, which can detectppmGrade moisture.

Application of Karl Fischer Furnace

Various polymer materials, insoluble samples such as plastic particles and plastic products, medical equipment, artificial bones, building sealants, etc

◆ Side reactions occur between the sample and Karl Fischer reagent, such as lubricant additives, engine oil, and samples containing iodine ions that react with them

◆ Ionic battery raw materials and finished products, such as various positive and negative lithium salts, separators, electrode sheets, etc

The moisture in the sample can only be released at high temperatures

The sample will contaminate the titration cell (lubricating grease, high viscosity samples...)

The integrated intake needle and the press type intake needle lifting system design allow for easy operation with only a gentle press during each injection. The intake and sample export are achieved within the same needle, eliminating the need to wait for the previous sample bottle to cool before replacing it. Additionally, the injection does not require opening the lid and can maintain a sealed state, making it particularly suitable for samples with low moisture content and easy moisture absorption.

Adopting high-qualityPIDTemperature control technology and importsPT100Platinum temperature sensor ensures the accuracy of temperature control and reduces errors caused by temperature factors.

Guanya brandCard furnace heating method moisture analyzerProduct Features:

1TheGY-KSL2000The headspace sampler of the Kashgar heating furnace adopts an empty core injection needle design, which can achieve both carrier gas input and water vapor output in one operation. At the same time, due to the new gas path design, the transmission of water vapor can be achieved with a very small flow rate. Each injection only requires changing the sample bottle for easy operation, without waiting for the sample bottle to cool down before changing the bottle cap. By using the classical Coulomb titration principle, the detection accuracy can reachppmGrade, very suitable for industries such as lithium batteries, plastic particles, and petrochemicals that have high requirements for moisture detection.

2The hollow core gas needle injection and gas delivery pipeline with heating function have no dead volume of water vapor and no condensation, making the operation simpler and greatly improving the accuracy and repeatability of the instrument.

3The temperature can reach300℃Can meet most sample testing needs and can be easily detected250-300℃Samples that can release moisture, such as salt samples.

4Using imported airflow flow meters,0-100ml/minAdjustable, suitable for samples with various water release rates;

5There is no need to wait for the previous sample bottle to cool down before proceeding to the next sample measurement. During the process of replacing the sample bottle, the sample bottle always remains sealed, resulting in higher and more accurate measurement efficiency. Especially for samples with strong moisture absorption, there is no need to worry about the interference of moisture in the air.

6Headspace sampling technology allows only gas to enter the reaction cup of the moisture analyzer without contaminating the reaction cup and electrolysis electrode.

7The sample export pipeline can be independently temperature controlled, and different temperatures can be set according to different samples, making it more flexible and convenient.

8Nitrogen cylinders or air pumps can be selected according to user needs.

9、High quality algorithms can accurately deduct moisture from the carrier gas and environment, reducing sample errors.

10Multiple endpoint control methods are available, including drift endpoint, potential endpoint, time endpoint, etc., to ensure suitability for various environments and samples.

11、8Formula5Method, result unitppm、%Themg/mgTheul/kgWait, optional, injection unitgThemlOptional, multiple combinations make it easier to use, without the need for users to manually convert.

12User customizable endpoint potential, suitable for various formulas and reagents from different manufacturers, whether imported or domestically produced.

13Customizing the sample mixing time can more effectively release the moisture in the sample.
