917 Coulometer Elf Generation

Integrated Karl Fischer Coulomb moisture analyzer

The 917 Coulometer Elf Generation is an all-in-one Karl Fischer coulometric moisture analyzer developed by Swiss company Vantone for daily analysis. It has two modes: Karl Fischer Coulomb method for moisture determination and bromine valence bromine index determination.

She is compact in size, integrating an operation panel, magnetic stirrer, titration tank, and suction and discharge pump into one. The overall structure is small and flexible, saving you valuable laboratory space.

After adding optional accessories, fully automated measurement can be achieved

Connecting the 885 Karl Fischer sample heating processor makes it easy to achieve measurement automation

• Paperless office, PDF reports

Can generate anti-counterfeiting PDF experimental reports and store them on USB storage or network computers, stylish and environmentally friendly

Personalized touch screen, quick access to experimental methods

You can create 14 shortcut icons on the touch screen and directly call the method for experimentation

• Equipped with reagent monitoring function to ensure maximum safety

The reagents are continuously monitored, and once the conditions such as the total number of injections or the total amount of injection water meet the customized quantity limit, the instrument will automatically prompt the user to replace the reagents.

• Tap the button to empty and add reagents

The device is equipped with a built-in suction and discharge pump system. You only need to press the button without opening the titration cup to empty the waste liquid and add reagents. The operator can completely avoid contact with the reagents.

KF icon displays real-time device operating status

The KF icon on the touch screen displays in real-time whether the device is in the pre titration state or in the sample preparation state

• Automatically sense the sample and start moisture measurement

No need to manually start moisture measurement. After the sample is added, the device can automatically sense the sample and start the measurement automatically

860 Karl Fischer Sample Heating Processor 885 Karl Fischer Sample Heating Processor

Flexible upgrade, compatible with 860 and 885 Karl Fischer sample heating processors

Not all samples can be directly injected, and it is recommended to use it in conjunction with a Karl Fischer furnace when the following conditions exist.

The sample cannot be completely dissolved (plastic particles, polyester chips, artificial bones, etc.)

• Side reactions occur between the sample and Karl Fischer reagent (lubricant additives, samples containing aldehydes and ketones, etc.)

• Slow release of sample moisture

Sample moisture can only be released at high temperatures

The sample will contaminate the titration cell (lubricating grease, etc.)

After being used in conjunction with a Karl Fischer oven, the moisture in the sample is heated and separated, transported to a titration cell via a dry carrier gas, and then measured for moisture in the titration cell.

Characteristics of Karl Fischer Furnace:

• Independent sealed sample bottle, suitable for direct sampling and sealing on site

No need for sample transfer during measurement, resulting in more accurate results

• Headspace heating method, small dead volume, and minimal sample cross contamination

860 type single sample grade Karl Fischer heating furnace, with optional heating chamber and sample bottle volume

The 885 fully automatic Karl Fischer heating furnace has 18 sample positions and can achieve fully automatic determination of sample blank and sample water content
