of vapor in the stream.
The references of record relied upon by the examiner in
support of rejections under 35 U.S.C. § 103 are:
Gelman 2,880,071 Mar. 31, 1959
Stenger et al. (Stenger) 3,459,938 Aug. 5, 1969
Jones et al. (Jones) 3,877,875 Apr. 15, 1975
Munk 4,942,018 Jul. 17, 1990
The following rejections under 35 U.S.C. § 103 are before us

Jones; and
d) claim 7, unpatentable over Stenger in view of Gelman.
Stenger, the principal reference, is directed to a method
and apparatus for determining the inorganic carbon content of a
liquid. Stenger’s method involves generating a stream of carrier
gas free of carbon dioxide by means of a carrier gas supply means
2, and injecting into the stream at inlet 64 (see Figure 2) a
sample of a liquid whose inorganic carbon content is to be
3A rejection of these claims as being anticipated by Stenger
has been withdrawn. See page 7 of the answer.
