Acored brandAKD-V8 Karl Fischer titration moisture analyzerOperation steps:
First assemble the moisture analyzer and connect it to the power supply, then turn on the power switch
Reagent debugging steps:
1. Suck methanol (other co solvents) until the liquid level covers the platinum tip of the electrode
2. Let the instrument perform a blank operation to deduct excess water from methanol (other solvents)
3. Perform multiple calibrations on the Karl Fischer reagent we use (more than 3 times, it is recommended to use deionized water or standard samples for calibration, or standard water samples for calibration)
4. After calibration, sample measurement can be carried out
Sample determination steps:
1. After sampling with an injector, place it on an analytical balance and weigh it. Click to remove the skin
2. Inject the sample into the titration cell
3. Take out the sampler and place it on the analytical balance for weighing. The weight displayed on the balance at this time is the weight of the sample
4. Enter the weight of the sample into the instrument and click to start the measurement
5. The measurement is completed, and the instrument displays the measurement results and automatically stores them

Acored brandAKD-V8 Karl Fischer titration moisture analyzermatters needing attention:
1、 Cannot display normally
Please check if the power connection wire, fuse, and power switch of the instrument are functioning properly.
2、 The instrument titration does not stop
1. Is the Karl Fischer reagent ineffective.
2. Too much water, too much sample injected.
3. Aldehydes, ketones or other components react with Karl Fischer reagent to produce water.
3、 Instrument testing is unstable
1. Environmental interference is significant.
2. Side effects.
3. Human error in operation.
4. Please check if there is any moisture adhering to the wall of the titration cell bottle (shake the electrolytic cell bottle)
4、 The measurement value has a large error
1. Inaccurate calibration, recalibrate.
2. The titration degree of the reagent has changed, and the titration degree measurement should be repeated.
