3 What are the special design issues for process Raman instruments  

Common characteristics of all viable process Raman instruments include the ability to measure at multiple locations, simultaneously or sequentially and in a variety of electrically classified or challenging environments with no special utilities. The instrument must be reasonably rugged and compact, and not require much attention, servicing, or calibration.12 Modem process Raman instruments essentially are turnkey systems. It is no longer necessary to understand the optical properties and other instrument details to successfully use the technique. The general design options will be described briefly, but more information is 

Safety must be the first consideration of any process analytical installation. Electrical and weather enclosures and safe instrument-process interfaces are expectations of any process spectroscopy installation. The presence of a powerful laser, however, is unique to process Raman instruments and must be addressed because it has the potential to injure someone. Eye and skin injuries are the most common result of improper laser exposure. Fortunately, being safe is also easy. Because so many people have seen pictures of large industrial cutting lasers in operation, this is often what operations personnel erroneously first envision when a laser installation is discussed. However, modern instruments use small footprint, comparatively low-power lasers, safely isolated in a variety of enclosures and armed with various interlocks to prevent accidental exposure to the beam.
