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.

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

) 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

Application:

(HR).

Inexceptionalcases,compoundscontainedinthewatercannotbeadequatelyoxidized.Thisresults

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.

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.
