Spectroscopic analyzing arrangement
First Claim
1. A spectroscopic analyzing arrangement comprising an ATR optical sampling plate having a front sample-contacting face and an opposed rear internally reflecting face, an anvil assembly located rearwardly of the rear reflecting face for allowing the sample-contacting face to be pressed sufficiently hard against the sample to receive spectroscopic information therefrom, and a reflection barrier located between the anvil assembly and the rear internally reflecting face of the sampling plate for preventing internally reflected light within the sampling plate from picking up spectroscopic information from the anvil assembly, characterised in that the anvil assembly comprises an anvil and a prism having an entry facet for receiving incident light which is directed to the sampling plate and an exit facet for allowing light reflected within the sampling plate to exit, the prism having a front face arranged to make contact with the rear reflecting face of the sampling plate via the reflection barrier and an opposed rear face against which the anvil locates.

Abstract
A spectroscopic analyzing arrangement comprises an ATR optical sampling plate with a front sample-contacting face and an opposed rear internally face. An anvil assembly is arranged so that the sample-contacting face can be pressed against the sample to receive spectroscopic information. A reflection barrier between the anvil assembly and the rear face prevents internally reflected light within the sampling plate from picking up spectroscopic information from the anvil assembly, thus enhancing the performance of the arrangement.
