Abstract: A cell for transmission and absorbance testing by means of infrared, UV/VIS or Raman spectroscopy is provided. The cell comprises a unique combination of seals and window configurations which allow use of inert fluoropolymer and/or elastomer seals instead of the convention sealing means used in spectroscopic sampling cells currently is use, particularly lead seals amalgamated with mercury which are not useable under RoHS rules particularly the EU RoHS directive, which is Directive 2011/65/EU of the European Parliament. The seal configuration also permits innovative cell configurations for UV/VIS spectroscopy and Raman which usually employ cuvettes comprised of glass or fused silica with fused seals or melted frit seals.
