1.4.13 Operating Principles A 1 /4" O.D. sample line is connected to the bleach operation
effluent pipe, either alkaline or acidic, (A). Customer-supplied
valve (B) is used to shut down flow to allow maintenance and
service of 6100CR and associated system components. The
primary filter (C) is in-line to remove any solid material from the
liquid flow that could cause clogging in the sampler. This filter is
of the type that can be disassembled and cleaned periodically.
Regulator (D) is used to throttle down the pressure from the
sample line, which can be as high as 120 psig, to a rate that
allows the sampler to fill the vials at 2 ml/second. Sample valve
(E) depending on its position either sends sample to the sampler
or in the case of a purge, to the drain.
This rate is set by adjusting the regulator in the sampler’s Calibrate
step. The ballast coil (F) allows for cooling of the sample,
which may leave the effluent pipe at temperatures as high as
185°F (85°C). The ballast coil is installed inside the refrigerator,
(G) which supplies the cooling for the sample line, as well as for
the stored samples. Cooled sample is injected into bottles by the
sample needle (H). The valve (I) is automatically opened and
closed by the sampler mechanism for the filling process and to
preclude contamination of the bottled sample once it is collected.
The bottle (J) along with 24 others in the rack are then taken to a
lab for analysis. There is a screen-filter (K) located at the inlet to
regulator D to catch any material that might escape from the
filter C.
