Method of and apparatus for performing fixed pathlength vertical photometry |
摘要 |
A system for performing vertical spectrophotometric determinations uses a vessel which has an upper transparent surface and a lower transparent surface which are spaced apart to define a known fixed pathlength through which a light beam is transmitted. The vessel also includes a portion disposed above the upper surface which may be a spout having an opening for allowing the introduction of substances into the containment portion.
