Lovibond ICx Operator Instruction Manual
PDF · Manufacturer document
For the relevant ICx method, use the same cell where possible and keep its orientation and position consistent.
Why
A cell change introduces differences in transmission, cleanliness and position that can conceal small low-colour differences.[1]
A cell fitting the chamber does not establish the required path length. Using the same cell does not remove cleaning and bubble checks.
What to confirm
Keep method conditions consistent between baseline and sample. If changing cells, reconfirm suitability and the baseline procedure under the manual; do not assume unconditional interchangeability. This is not a universal rule for every optical instrument.
