Measuring instruments are typically built to measure a wide range of samples. However, the measuring cell, hoses, and connections must be cleaned after measurement to keep the device in good working condition and make sure the measurement on the next sample delivers correct results.
Choosing the most suitable solvent to clean the measuring cell(s) of a scientific instrument depends on the sample or chemical which needs to be removed from the device. The aim of a cleaning procedure is to leave the measuring device ready to use for the next measurement or experiment.
If the measuring device has a sample changer, the cleaning program can be predefined to automatically use specific solvent combinations and drying times.
Before using a solvent for the cleaning task you need to consider:
- The type of sample which needs to be removed from the measuring cell
- Which type of solvent could be used
- Which order to use the solvents in
