This continuous refractive index mon itor provides constant indication of liquid chromatographic and process streams relative to refractive index of the stream effluent. The detecting compartment, which is mounted di rectly below a chromatographic col umn or in the stream to be monitored, is said to be the most sensitive avail able for reading reflective differences. The monitor's principle of operation is as follows: As the refractive index of the eluted stream changes, the in tensity of the reflected light also changes, causing a difference in out put from the instrument. This differ ence is registered on a recorder and is depicted by "peaks" similar to those of a gas chromatograph. Nester/Faust Mfg. Corp., 2401 Ogletown Road, Newark, Del. 414
