This is an appeal from the final rejection of claims 1-5.
Claim 6, the other claim remaining in the present application,
has been allowed by the examiner. Claim 1 is illustrative:
1. A system for sampling and determining presence of certain
contaminants including nitrogen containing compounds and
aromatic hydrocarbons in items moving seriatim past a test
station comprising:
means for directing fluid into proximity with said item
as it reaches said test station to displace vapors of
contaminants;
means for evacuating a sample of vapors so displaced from
the item by the fluid by applying suction thereto;
means for splitting the evacuated sample into first and
second portions;
a chemiluminescence detector for analyzing the first
portion of the sample to determine presence or absence of
contaminants of nitrogen containing compounds;
said chemiluminescence detector including,
means for heating the first portion of the sample
evacuated;
means for mixing the heated sample portion with
ozone to cause a chemical reaction therewith in order to
generate chemiluminescence of the reactants; and
means for optically analyzing said chemiluminescence
to determine the presence or absence of said certain
contaminants;
means for illuminating the second portion of the sample
with radiant energy to generate fluorescence in the sample;
and
