General Notes
• Priortomeasurementensurethatthesampleissuitableforanalysis(nomajorinterference)and
doesnotrequireanypreparationi.e.pHadjustment,ltrationetc.
• Reagentsaredesignedforuseinchemicalanalysisonlyandshouldbekeptwelloutofthereach

Chemical Method Notes:
Method:
The sample is heated at 150
o
Cfortwohoursinthepresenceofpotassiumdichromate,whichisa
strong oxidizing agent. Organic compounds in the sample are oxidized, reducing the dichromate ion
(Cr
2
O
7
2–
) to the green chromic ion (Cr
3+
).
IntheLowRange(LR)Test(0-150mg/L),theamountofremainingCr
6+
is measured; In the
MidRange(MR)(0-1,500mg/L)or(HR)(0-15,000mg/L),theamountofCr
3+
produced is
measured.Theresultsaremeasuredastheamountofoxygen(O

)consumedperliterof
water sample. The LR and MR test is displayed in mg/L while the HR test shows g/L.
TheCODreagentcontainsbothmercuryandsilver—themercurycontrolschloride

Application:
Samplescanbemeasuredifthechloridecontentdoesnotexceed1,000mg/l(LR/MR)or10,000mg/l
(HR).
Inexceptionalcases,compoundscontainedinthewatercannotbeadequatelyoxidized.Thisresults
inlowreading,comparedwiththereferencemethod.

Preparing the Sample
Openareactionvialwithawhitecapandaddthespeciedvolume.
(Ensurethatappropriatepersonnelsafetyequipmentisused.)
LR-/MR: 2 ml water sample
HR: 0.2 ml water sample
Prepareablank(Note1)byusingdeionizedwater(TOC-free)insteadofthesample
(LR/MR: 2 ml, HR: 0.2 ml).
Replacethecaptightly.Invertthevialgentlyseveraltimestomixthecontents(Thevialwillbecome
hotduringmixing!)anddigestthevialsfor120minutesinthereactoratatemperatureof150°C.
Removethevialsfromthereactorandallowthemtocooldownto60°Corless.Mixthecontentsby
invertingeachvialseveraltimeswhilestillwarm.Thenallowthevialstocooltoambienttemperature
beforemeasuring.
Guidelines for photometric measurements
1. Runsamplesandblankswiththesamebatchofvials.
Theblankisstablewhenstoredinthedarkandcanbeusedforfurthermeasurementswithvials
fromthesamebatch.
2. Don‘tplacehotvialsintheadapter.Allowthevialstocooltoroomtemperaturefor
a minimum 45 minutes. It is recommended to leave the vials to cool over night.
3. Suspended solids in the vial lead to incorrect measurements. For this reason it is important to place
thevialscarefullyintheadapter.Theprecipitantatthebottomofthesampleshouldnotbe
suspended.
4. Cleantheoutsideofthevialswithatoweltoremovengerprintsorothermarks
.
5. Avoidspillageofwaterorreagentsolutionintothesamplechamberbecausethiscanleadtoincor-
rect test results.
6. Contaminationofthetransparentcellchambercanresultinincorrectreadings.Checkatregularin-
tervalsand–ifnecessary–cleanthetransparentcellchamberusingamoistclothorcottonswab.
7. Largetemperaturedifferencesbetweentheinstrumentandtheenvironmentcanleadtoerrors–
e.g.duetotheformationofcondensationinthecellchamberoronthevial.
8. Toavoiderrorscausedbystraylightdonotusetheinstrumentinbrightsunlight.
