8 Type Xerolyt Electrodes

59 905 939 Printed in Switzerland

1 Introduction

Thesegeneralinstructionsmustbereadilyavailabletoope-

ratorsoftheelectrodeatalltimes.Beforeusingtheelectro-

de,theseinstructionsmustbereadandunderstoodbyall

operatingpersonnel.

Owingtotheirspecialcharacteristics,pH/redoxelectrodes

withaXerolytreferencesystemaresuitableforthefollowing

applications:

–Measurementsinhighlycontaminatingsolutions

– Measurements in emulsions and suspensions

–Measurementsinefuents/wastewater

– Measurements in solutions containing proteins

–Measurementsinsolutionswithahighsuldecontent

–Measurementsinhotalkalinesolutions(withTypeHApH

glass)

–Installationinmeasuringandcontrolloopswithwidepres-

sureuctuations.

Xerolyt electrodes are notsuitable forthe followingappli-

cations:

–Measurementswheretheelectrodeissteam-sterilized

–Measurementswithlarge, long-term, temperature varia-

tions

–MeasurementsinsolutionswithapHvalueofpH<2

–Measurementsinsolutionscontainingchlorine

2 Safety remarks

TheXerolyt electrodesareintendedsolelyfor thepurpose

describedin§1above.Theelectrodesconsistpartlyofglass.

Iftheyaretobecleanedorcalibratedusingacidoralkaline

solutions, protective clothing (goggles and gloves) must

beworn.Inaddition,localandin-house-safetyregulations

mustbeobserved.Werecommendthattheelectrodesonly

beputintooperationinconjunctionwithoriginalproducts/

accessoriesfromMETTLERTOLEDO.Theelectrodesmaybe

operatedandservicedonlybypersonnelfamiliarwiththe

equipmentinquestionandwhohavereadandunderstood

theseinstructions.

4 Installation and preparation for use

 a Carefullyinspecttheelectrodeondeliveryformechanical

damagetothemembraneortheshaft.Electrodesshowing

anydefectsshouldbesentbackintheoriginalpackaging,

accompaniedbytherelativeinvoicenumber.

 b Removethewateringcapandrinseelectrodewithdistilled

water. After rinsing, a pH electrode unit should be dried

bycarefuldabbingwithapaperhandkerchieforKleenex

tissue.Donotrubtheglassmembrane,sincethiscanlead

toverysluggishresponse.

 c Removeanyairbubblespresentinthemembranechamber

oftheglasselectrodebylightlyswingingroundinavertical

plane.

 d pHelectrodeassemblieswithdryglassmembranesmust

beconditionedbyimmersionforseveralhoursin3mol/l

KClinthesuppliedwateringcap(useapprox.1ml).

5 Calibration and measurement

Xerolytelectrodesrequire2-pointcalibration.Tocalibrate,

rstremovethewateringcap.Theelectrodeisthendipped

insuccessionintotwodifferentbuffersolutionswithgiven

pHreferencevalues,andthetransmittercalibratedtothese

buffervalues(forexamplebufferpH4.01andpH7.00).

Pleaserefertotheinstructionmanualofthetransmitterfor

details.

6 Maintenance

The electrode with polymer electrolyte Xerolyt cannot be

relled.Theelectrodemustnotbestoreddry.Intheevent

thattheelectrodedriesout,itisnecessarytoreconditionit

beforeusebyimmersioninFriscolyt™(Orderno.51340

053)foratleast24hours.Theelectrodeshouldbestored

withttedwateringcapcontaining3mol/lKClorMettler-

Toledo Friscolyt. After each working cycle, the electrode

tip and the apertures (diaphragms) must be thoroughly

cleanedusingde-ionizedwater.Regenerationoftheglass

membraneofapHelectrodewithHF(hydrouoricacid)is

notrecommended,sinceHFwillattacktheXerolytreference

system.

7 Disposal

Ifnorelativeofcialregulationsareinforce,usedordefecti-

veelectrodeandthepackagingcanbedisposedasordinary

householdwaste.

8 Warranty

Intheeventofmanufacturingfaults,12monthswarranty

fromdateofproductionisgranted.
