Sample amount
If the measuring cell is clean and dry, you need approx. 1 mL of sample.
If you are measuring without cleaning and drying between the samples, you need
a higher amount of sample because you have to flush residues of the previous
sample out of the measuring cell to avoid cross-contamination.
