Overview
The HI934-02 is a Karl Fischer Coulomb Titrator from the HANNA brand with High Accuracy, Flexibility and repeatability. Designed to perform titration for a wide range of applications, the instrument can analyze water content in the range of 1 ppm to 5%, effectively monitor KF reactions, detect endpoints and perform all necessary calculations and plotting.
Features
1. Small footprint, requires minimal workbench space
2. The shell is made of strong, chemical corrosion resistant plastic
3. Powerful built-in algorithms for termination criteria based on fixed mV endpoints or absolute/relative drift
4. Sample analysis averages and statistics
5. Minimize water vapor entry through a sealing solvent system
6. Balancing interface for automatic weighing
7. Supports 100 titration methods
8. User-defined reports
9. Clear display of warnings and error messages
Principle
The HI934-02 uses the Karl Fischer Coulomb Titrimetric method to automatically monitor the KF reaction and detect the endpoint by adjusting the polarization current in the range of 1-10 μA and the voltage range of 2-1100mV. The instrument uses Magnetic Stirrer, electronically adjusts the stirring speed of 200-2000RPM, and realizes High Accuracy titration analysis through a sealing solvent system and built-in algorithms.
Applications
Liquid sample analysis, solid sample analysis
Steps
1. Preparation of samples (liquid or solid, externally dissolved or extracted)
2. Set the titration method (support 100 methods to choose from)
3. Start pre-titration conditions (automatic)
4. Perform background drift correction (automatic or user selectable)
5. Set endpoint metrics (fixed mV persistence, relative drift stop or absolute drift stop)
6. Select Measurement Speed (Dynamic with 3 Speed Settings)
7. Start titration analysis
8. View result statistics (mean, standard deviation)
