Inlet Valve –
Accepts .the .sample .stream .via .1/4 .inch .NPTF .connector . . .
The .user .must .supply .the .sample .with .a .pressure .between .14 .and .100 .psig . .
Inlet Filter –
60-micron .stainless .steel .filter .traps .particulate .matter .in .
sample .stream . .
Bypass Valve –
Use .to .redirect .flow .in .bypass .system .
Pressure Regulator –
Adjusts .flow .on .incoming .sample .stream .
Flow Meter –
Measures .sample .flow .rate .(40 .mL/min .nominal .flow .is .
required) .
Calibration Shut Off Valve –
Use .to .stop .flow .of .sample .from .flow .meter .
to .restrictor .tubing .
Restrictor Tube Assembly –
Use .in .conjunction .with .pressure .regulator .to .
lower .downstream .pressure .
Reagent Manifold –
Directs .sample .flow .in .and .out .of .reagent .bottle .
assembly .
Reagent Bottle Adapter Assembly –
Connects .reagent .bottle .assembly .to .
manifold .
Diffusion Tubing Assembly –
Semi-permeable .tubing .through .which .
reagent .diffuses .into .the .sample .
Reagent Bottle –
Contains .water-soluble .amine, .which .raises .the .sample .
pH .to .approximately .11 . .
Reagent Bottle Bracket –
Secures .reagent .bottle .
Flow Cell –
Contains .reference .electrode, .sample .electrode, .and .ATC .probe . .
Diverter Valve –
Allows .the .flow .cell .reservoir .to .fill .during .calibration .by .
forming .a .closed-loop .system . .
Re-circulation Tube –
Tube .through .which .sample .(assisted .by .air) .is .
pumped .into .the .flow .cell .– .used .to .mix .solution .in .a .closed-loop .during .
calibration . .
