Abstract

An analyzer such as a two beam infrared analyzer is assembled in building block fashion and includes a radiation source module and a detection module tied together by rods and in optical alignment with each other. Intermediate or "cell"-modules are hung on the rods and all adjacent, interfacing faces of the several modules are constructed for indexing, preventing lateral deflection when the fastened rods hold all parts together.
