SSEMBLY
As shown in the exploded view of Figure 5-3A, the detector/magnet assembly consists
of three major subassemblies: the magnet assembly, the detector assembly, and the
optical bench assembly.
The magnet assembly includes a sample preheating coil. It is connected into the
sample line, upstream from the detector, and is heated to approximately the same
temperature as the detector assembly.
