The .sample .enters .the .Thermo .Scientific .Orion .2118XP .oxygen .scavenger . 

monitor .and .passes .through .the .inlet .valve, .bypass/needle .valve, .inlet .filter, . 

pressure .regulator, .flow .meter .and .into .the .restrictor .tubing . . .The .sample . 

then .passes .through .the .fluid .connector .block .into .a .reagent .bottle .through . 

a .diffusion .tubing .assembly .where .pH .adjustment .takes .place .and .iodine . 

is .added . . .The .pH-adjusted .sample .then .flows .back .through .the .connector . 

block .into .the .reagent .mixing .loop .where .the .oxygen .scavenger .in .the . 

sample .mixes .with .iodine .reagent .to .form .iodide . . .The .sample .then .passes . 

the .iodide .electrode, .reference .electrode .and .temperature .probe .and .flows . 

into .an .atmospheric .drain .via .the .diverter .valve . 

ORION 2118XP 

Oxygen Scavenger 

I-4



The .oxygen .scavenger .present .in .the .sample .reacts .with .the .iodine .to .form . 

iodide .ion: 

. OSred + X • I2 → 2X • I¯ + OSox 

Where: . 

. OSred .= . .oxygen .scavenger .reduced 

. OSox . .= . .oxygen .scavenger .oxidized . 

The .iodide .sensing .electrode .responds .logarithmically .to .changes .in .the . 

resulting .iodide .ion .concentration . . .This .response .is .described .by .the . 

Nernst .equation: . 

E = Eo + 2.3 (RT/nF) log (C/Ciso) 

Where: . 

E . = .measured .electrode .potential, .mV . 

Eo . . = .potential, .when .C .equals .Ciso, .mV . 

R . = .ideal .gas .constant . 

T . . = .temperature .of .sample, .degrees .K . 

n . . = .valence .of .ionic .species .(-1 .for .iodide .ion) . 

F . . = .Faraday’s .constant . 

C . = .effective .iodide .concentration .(activity) . 

Ciso .= . .concentration .(activity) .of .iodide .ion .where .potential .E .is . 

temperature .independent .(isopotential .point) . 

The .above .equation .indicates .that .the .measured .potential .varies .with .both . 

temperature .and .the .concentration .of .the .ion .of .the .interest . . .In .order .to . 

eliminate .error .caused .by .fluctuations .in .sample .temperature, .the .2118XP . 

microprocessor .constantly .updates .temperature .corrections .from .data . 

supplied .by .the .ATC .probe . . 

From .the .Nernst .equation, .the .theoretical .response .of .an .iodide .ion . 

selective .electrode .to .a .ten-fold .change .in .concentration .at .25 .˚C .is . . 

-59 .16 .mV . . .This .is .referred .to .as .the .electrode .slope .(S) . . .Most .electrodes, . 

however, .do .not .exhibit .a .theoretical .slope . . .Therefore, .the .instrument .is . 

calibrated .to .determine .its .actual .value . . .Two .standards .are .used .to .provide . 

information .necessary .for .the .microprocessor .to .compute .the .actual .slope . 

and .E0 .for .use .during .sample .analysis . . 

I-5



Acid .is .added .to .the .sample .to .prevent .a .competing .reaction .from . 

occurring: 

. 3I2 .+ .H2O . .→ .5I¯ .+ .IO3¯ .+ .6H+ 

Maintaining .acidic .conditions .prevents .the .release .of .iodide .which .would . 

cause .high .apparent .reductant .readings . 

The .pH .adjustment .and .iodine .addition .are .accomplished .by .the .patented . 

passive-diffusion .process .wherein .the .sample .passes .through .a .length .of . 

tubing .in .the .reagent .bottle .that .contains .the .acid .reagent .and .iodine . . .The . 

reagent .and .iodine .diffuse .through .the .tube .wall .and .mix .with .the .sample . . . 

This .passive .method .eliminates .sample .contamination .problems .due .to . 

reagent .contamination .and .makes .the .fluid .handling .apparatus .simple .and . 

reliable . .

Principles of 

Calibration 

Dynamic Two Point 

Calibration (DYN) 

Offline Calibration 


Calibration .procedures .for .analytical .instruments .are .important .and .must . 

be .performed .carefully . . .The .Thermo .Scientific .Orion .2118XP .oxygen . 

scavenger .monitor .uses .a .dynamic .two .point .calibration .that .utilizes . 

advanced .electrode .technology .in .combination .with .a .dynamic .calibrator . . . 

The .dynamic .two .point .calibration .procedure .provides .maximum . 

calibration .accuracy .and .requires .the .use .of .the .dynamic .calibrator, .Cat . . 

No . .21DC00 .(115 ./ .220 .V) . . .In .addition .to .calculating .the .Eo .value .of . 

the .electrode, .as .is .done .in .an .offline .calibration .procedure, .this .procedure . 

determines .electrode .slope . . .To .perform .a .dynamic .two .point .calibration, . 

the .Orion .2118XP .is .first .connected .to .a .reductant-free .sample .stream . . . 

An .appropriate .diluted .standard .is .prepared .and .then .a .syringe .is .filled . 

with .the .diluted .standard .and .mounted .on .the .calibrator . . .The .calibrator . 

is .then .mounted .near .the .monitor .and .the .syringe .tubing .is .connected .to . 

the .standard .injection .port . . .By .adjusting .the .calibrator .pump .settings, . 

two .different .flow .rates .produce .two .known .standards .that .are .diluted .into . 

the .sample .background . . .By .pressing .the .appropriate .keys .on .the .monitor . 

when .prompted, .the .monitor’s .microprocessor .completes .the .calibration . . . 

After .allowing .approximately .30 .minutes .for .the .calibration .solution .to .be . 

flushed .from .the .system, .the .Orion .2118XP .can .begin .sample .measurement . 

again . . 

In .addition .to .a .dynamic .two .point .calibration, .an .offline .calibration .can . 

be .performed .with .some .oxygen .scavengers . . .Since .the .oxygen .scavenger . 

concentration .in .feedwater .is .normally .controlled .over .a .rather .narrow . 

range, .usually .an .offline .calibration .procedure .is .sufficient .to .provide . 

accurate .results . . .The .offline .calibration .procedure .has .the .advantage .of . 

being .quick .and .easy .to .perform . . .If .sample .reductant .concentrations .are . 

expected .to .vary .widely .from .day .to .day .or .if .online .verification .of .monitor . 

readings .is .desired, .a .dynamic .two .point .calibration .should .be .performed . . 

The .offline .calibration .feature .of .the .Orion .2118XP .allows .the .user .to . 

adjust .the .monitor .to .values .determined .by .alternate .methods .used .in .their . 

laboratory .such .as .a .standard .colorimetric .method . 

The .offline .calibration .is .essentially .a .one .point .calibration . . .To .perform .an . 

offline .calibration, .a .sample .is .taken .from .the .bypass .of .the .instrument; .the . 

sample .concentration .value .is .stored .in .memory; .the .sample .is .analyzed .by . 

an .alternate .method .of .choice; .the .previously .stored .reading .is .adjusted .to . 

the .lab .method .result; .and .the .instrument .is .then .returned .to .the .analysis . 

mode . . .The .term .“offline .calibration” .refers .only .to .the .fact .that .a .sample . 

from .Orion .2118XP .bypass .is .taken .“offline” .for .laboratory .analysis; .in . 

fact, .no .downtime .is .experienced .during .the .procedure .and .the .instrument . 

remains .online .throughout . .
