bers that would destroy the usefulness of such valves

and the sensing device, thereby reducing the analysis
in high speed chromatography. Coincident with these
older types of sample valve control are added space re
quirements, which are undesirable ‘from the point of
view of the analysis time cycle, as noted previously.
The present invention employs a ?exible toroidal ring
to open and close the passages between adjacent mem
bers of a plurality of ports in a sampling valve by means
of ganged pistons. These pistons are controlled by a
power gas pressure against selected areas of an actuating
diaphragm adjacent to the pistons. The valve of this
invention is designed to permit a power gas pressure of
about 20 p.s.i.-g. to control the flow of a carrier gas, at a
pressure as high as 150 p.s.i.g., through the sampling
valve of a chromatographic analyzer.
It is, therefore, an object of this invention to provide a
sampling valve ‘for use in a chromatographic analyzer,
whereby the analysis time cycle can be reduced.
70
It is also an object to provide a fast response, small
internal volume, ?uid-actuated, piston-controlled, toroidal
tion indicating the alternate position of operation; and

‘Reference is now made to the drawing in detail, where

while, the second side of sampling valve 22 is being vented

26. A carrier gas, such as helium or hydrogen, is passed
via conduit 27 to sampling valve 22, then through con
duit 28 to sorption column 29. A gaseous sample from
the process stream, introduced to sampling valve 22 via
conduit 31 is being circulated through the sample loop

is passed along by the carrier gas, via conduit 28, to
sorption column 29, where constituents of the sample to
be identi?ed and measured, are absorbed or adsorbed, de
pending upon the nature of the contact material. These
constituents are then selectively desorbed by a continuing
?ow of carrier gas through column 29.
The sorption column effluent passes through an analyzer,
indicated ‘as thermal .conductivitycell assembly 34, via
conduit 36. The output signal from assembly 34 is passed 10
to a recording instrument ‘(not shown), which can be a
conventional strip chart recorder. A stream of carrier
