After analyzing arsenic using a spectrophotometer, the cuvettes are difficult to clean; by washing them with alcohol, the cuvettes tend to get damaged

Is arsenic highly toxic? You can check the MSDS; it might contain the answer you’re looking for

Hydrochloric acid:ethanol = 1:2 can be used; immerse the cuvette in it for a certain period of time – the duration should not be too long – and then rinse it with water

The cuvettes we have used are first rinsed several times with the mobile phase after flushing the column with liquid, and then rinsed once with anhydrous ethanol

I used the method from floor 5, and the results are pretty good so far; I would like to express my gratitude
