ABSTRACT:
A spectrometer system is disclosed in which a single ended internal reflectance element (IRE) is readily insertable into, and removable from, liquid samples being analyzed. The IRE is carried by an articulated housing construction having enclosed radiation passages, through which radiation is directed by a plurality of mirrors. The IRE-supporting enclosure is pivotally mounted by means of aligned rotatable members, which permit the IRE to be moved into and out of samples without disconnecting or re-purging the enclosed radiation passages.
