Production of lithium battery material moisture analyzer

Specialized Karl Fischer moisture analyzer for lithium battery materials and electrode membranesUsing an empty core injection needle design, one operation can achieve both carrier gas input and water vapor output. 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 the replacement of the sample bottle, which is convenient to operate without waiting for the bottle cap to cool down. The detection accuracy can reachppmGrade, very suitable for industries such as lithium batteries, plastic particles, and petrochemicals that have high requirements for moisture detection.

1. The KHF-100 Karl Fischer oven headspace sampler 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 the replacement of the sample bottle for easy operation, without waiting for the sample bottle to cool down before replacing the bottle cap. The classic Coulomb titration principle can achieve a detection accuracy of ppm level, which is very suitable for industries such as lithium batteries, plastic particles, and petrochemicals that have high requirements for moisture detection.

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

3. A temperature of up to 300 ℃ can meet the requirements for most sample testing, and can easily detect samples that require 250-300 ℃ to release moisture, such as salt samples.

4. Adopting imported airflow flowmeter, adjustable from 0-100ml/min, suitable for samples with various water release rates;

5. There 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.

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

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

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

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

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

11. 8 formulas and 5 methods, with optional units of ppm,%, mg/mg, ul/kg, etc. for results, and optional units of g and ml for injection. Multiple combinations make it easier to use without the need for users to manually convert.

12. User customizable endpoint potential, suitable for various formulas and reagents from different manufacturers. Whether imported or domestically produced reagents can be used, users do not need to purchase specific brands of reagents.

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