titleOfInvention | SPECTROMETRIC MONITOR FOR THE POLLUTION OF A SUPERCRITICAL LIQUID. |
abstract | A system detects the presence of contaminants in a supercritical fluid flow. When the latter leaves the cleaning chamber (12) through the outlet orifice (16), a sample flow is taken which is introduced into a second chamber (22) and which is subjected to reduced pressure prevailing in a contaminant measurement zone (24). The supercritical fluid turns to gas (as shown by lines 30) at this reduced pressure, while the contaminants remain in a non-gaseous state. A plate (36) with attenuated total reflectivity is used to detect by spectrophotometry the presence of non-gaseous contaminants which are deposited on the surface (48) of this plate, in the contaminant measurement zone (24). This system makes it possible to detect by spectrophotometry in supercritical fluids the presence and nature of contaminants and to monitor both cleaning and extraction processes. |
