摘要： An apparatus for performing photochemical measurements on a liquid or liquid-containing sample (LS) comprising: a light generating system (LGS), an optical system (OS) configured for directing light from the light generating system towards the sample and a sensing system (SS, SS') for measuring at least one optical property of the sample, characterized in that:
- the light generating system is configured for generating light with intensity levels adjustable within a range, spanning at least three and preferably at least five orders of magnitude; and in that
- the optical system is configured for directing light from the light generating system towards the sample so as to generate a substantially uniform light intensity level, within a cylindrical region of the sample having a height larger than or equal to five time its radius.
