Jackson discloses a process for cleaning, sterilizing and
preserving materials wherein the materials are exposed to a dense
fluid which is “a gas or a mixture of gases compressed to a
supercritical, liquified, or multi-phased states to achieve
liquid-like densities” (col. 2, line 65 - col. 3, line 7; col. 4,
lines 1-19). Jackson teaches that in-line, real-time chemical
analysis instrumentation techniques such as supercritical fluid
gas chromatography may be used to examine dense fluid extracts
from the cleaning chamber as an indicator of the cleanliness of
the material being cleaned (col. 11, line 68 - col. 12, line 4;
col. 16, lines 11-16).
Burgess discloses, in one embodiment, an integrated
spectrometer for the continuous chemical analysis of liquid,
gas, solid or mixed phases in a reaction volume (col. 4, lines
2-8; col. 5, lines 1-3). The spectrometer includes a waveguide
into which multi-wavelength electromagnetic radiation is
introduced through an entrance grating (col. 4, lines 17-20).
The electromagnetic radiation propagates through the waveguide,
which has one surface in contact with the reaction volume, and
exits through an outlet grating to an electromagnetic radiation
sensing device (col. 4, lines 20-34). Each time a propagated
beam of electromagnetic radiation bounces off the surface of the
