￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 5 Performing a determination 5 Performing a determination Moisture determinations according to the heating method require the conditioning of the entire tubing system and of the KF titration cell before a determination can be carried out. Because the sample vials and the septum seals may contain small amounts of moisture, three to five blank value determinations must be carried out with sealed, empty vessels.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 5.1 Conditioning the system It is advantageous to have air bubbles stirred into the working medium and forcefully broken up in the process. The air in the KF titration cell must also be dried. Conditioning the working medium 1 Load a conditioning method on the KF titrator and begin the conditioning by pressing the [Start] key. You will find the necessary settings in the KF titrator manual.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6.1 General 6 Handling and maintenance 6.1 General The 860 KF Thermoprep requires appropriate care. Excess contamination of the instrument may result in functional disruptions and a reduction in the service life of the sturdy mechanics and electronics of the instrument. Severe contamination can also have an influence on the measured results. Regular cleaning of exposed parts can prevent this to a large extent. Spilled chemicals and solvents must be removed immediately.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 6 Handling and maintenance addition, various application bulletins are also available on the subject, which also contain Standard Operating Procedures (SOP = Standard Operating Procedure) for testing analytical measuring instruments for reproducibility and correctness. Maintenance Electronic and mechanical functional groups in Metrohm instruments can and should be checked as part of regular maintenance by specialist personnel from Metrohm.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 7.1 Problems and their solutions 7 Troubleshooting 7.1 Problems and their solutions Problem Cause Remedy The drift is very high during conditioning. Molecular sieve of drying flasks and/or the titration cell exhausted. Replace molecular sieve. The titration cell is leaking Check seals. If necessary, replace. The sample is non-homogenous Reduce the size of the sample before weighing in. Not the entirety of the moisture expelled.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 8 Appendix 8 Appendix 8.1 Practical instructions Carrier gas selection If the hot sample is sensitive to air or oxygen (decomposition) and releases substances that disrupt the KF reaction, then nitrogen (N2) should be used as the carrier gas. Temperature settings The temperature selected should be as high as the sample allows (high temperature = shorter analysis time). The sample may not however decompose. It must not give off any oxidizable substances, only water.
