1. First, fill the cuvette with dispersant (6 ml minimum).
2. Insert the cuvette into the SV cell and then the instrument. Perform a background
and initial alignment.
3. The SV cell can then be removed and, using the syringe (with syringe tip attached),
extract an amount of dispersant.
4. Sample is now added into the cuvette, again to a 6ml minimum level.
5. Reinsert the SV cell into the instrument, perform another alignment and recheck
the obscuration.
6. If the obscuration is incorrect, remove the cuvette and add either more sample or
dispersant as required.
7. Repeat until the obscuration is correct, then continue with the measurement.
