Temperatura ne sme preseči 105 oC.
Continue to stir, scraping the bottom of the dish, until bubbles stop forming.
Nadaljuje se z mešanjem in pri tem se drgne dno posode, dokler mehurčki ne prenehajo izhajati.
In order to ensure complete elimination of moisture, reheat several times to 103 oC ± 2 oC, cooling to 93 oC between successive heatings.
Da se zagotovi popolna odstranitev vlage, se večkrat segreje na 103 ± 2 oC ob ohlajevanju na 93 oC med zaporednimi segrevanji.
Then leave to cool to room temperature in the desiccator (3.4) and weigh.
Nato se pusti, da se vzorec v eksikatorju (3.4) ohladi na sobno temperaturo, in se stehta.

Postopek se ponavlja, dokler izguba mase med dvema zaporednima tehtanjema ni manjša od 2 mg.
N.B
Opomba
An increase in the weight of the sample after repeated heating indicates an oxidation of the fat, in which case calculate the result from the weighing carried out immediately before the weight began to increase.
Povečanje mase vzorca po ponovljenem segrevanju kaže na oksidacijo maščobe, v tem primeru je treba upoštevati rezultat tehtanja, izvedenega neposredno pred začetkom povečevanja mase.

1 g vzorca se natehta na 0,001 g natančno in se prenese v bučko naprave za razklop.
Add 15 g of potassium sulphate (3.1), an appropriate quantity of catalyst (3.2) (0,3 to 0,4 g of copper (II) oxide or 0,9 to 1,2 g of copper (II) sulphate pentahydrate), 25 ml of sulphuric acid (3.4) and if required, a few granules of pumice stone (3.12) and mix.

Heat the flask moderately at first, swirling from time to time if necessary until the mass has carbonised and the foam has disappeared; then heat more intensively until the liquid is boiling steadily.
Bučka se najprej zmerno segreva in po potrebi občasno obrne, dokler masa ne zogleni in pena ne izgine; nato se močneje segreva do enakomernega vretja tekočine.
Heating is adequate if the boiling acid condenses on the wall of the flask.
Segrevanje je ustrezno, če se vrela kislina kondenzira na stenah bučke.
Prevent the sides from becoming overheated and organic particles from sticking to them.
Paziti je treba, da se stene bučke ne pregrejejo in da se organski delci ne sprimejo nanje.
When the solution becomes clear and light green continue to boil for another two hours, then leave to cool.
Ko se raztopina zbistri in obarva rahlo zeleno, se pusti vreti še 2 uri, nato pa pusti, da se ohladi.
Add carefully enough water to ensure complete dissolution of the sulphates.
Previdno se doda toliko vode, da se sulfati povsem raztopijo.
Allow to cool and then add a few granules of zinc (3.3), if required.
Pusti se, da se ohladi, nato pa se po potrebi doda nekaj zrnc cinka (3.3).
Proceed according to 5.2.1 or 5.2.2.
Nadaljuje se v skladu s točko 5.2.1 ali 5.2.2.

Bučka za razklop se poveže s kondenzatorjem naprave za destilacijo in konica kondenzatorja se potopi v tekočino v zbirni bučki vsaj do globine 1 cm (glej opombo 8.3).
Slowly pour 100 ml of sodium hydroxide solution (3.9) into the digestion flask without loss of ammonia (see observation 8.1).
V bučko za razklop se počasi vlije 100 ml raztopine natrijevega hidroksida (3.9) tako, da ne pride do izgube amonijaka (glej opombo 8.1).
Heat the flask until the ammonia has distilled over.
Bučka se segreva do popolne destilacije amonijaka.

Destilacija v borovo kislino
Where titration of the ammonia content of the distillate is performed manually, the procedure mentioned below applies.
Pri ročni titraciji amonijaka iz destilata se uporablja spodaj navedeni postopek.
Where the distillation unit is fully automated to include titration of the ammonia content of the distillate, follow the manufacturer's instructions for operation of the distillation unit.
Kadar je destilacijska enota v celoti avtomatizirana in vključuje titracijo amonijaka iz destilata, se upoštevajo navodila proizvajalca za upravljanje z destilacijsko enoto.
Place a collecting flask containing 25 ml to 30 ml of the boric acid solution (3.18) under the outlet of the condenser in such a way that the delivery tube is below the surface of the excess boric acid solution.
Zbirna bučka s 25–30 ml raztopine borove kisline (3.18) se postavi pod izhodno odprtino kondenzatorja tako, da je dovodna cev pod površino presežka raztopine borove kisline.
Adjust the distillation unit to dispense 50 ml of sodium hydroxide solution (3.9).
Destilacijska enota se nastavi tako, da se dovaja 50 ml raztopine natrijevega hidroksida (3.9).
Operate the distillation unit in accordance with the manufacturer's instructions and distil off the ammonia liberated by the addition of the sodium hydroxide solution.
Destilacijska enota se upravlja v skladu z navodili proizvajalca, sproščeni amonijak pa se destilira z raztopino natrijevega hidroksida.
Collect distillate in the boric acid receiving solution.
Destilat se zbere v raztopino borove kisline.
The amount of distillate (time of steam distillation) depends on the amount of nitrogen in the sample.
Na količino destilata (čas parne destilacije) vpliva količina dušika v vzorcu.
Follow the instructions of the manufacturer.
Upoštevati je treba navodila proizvajalca.
In a semi-automatic distillation unit, the addition of excess sodium hydroxide and the steam distillation are performed automatically.
V polavtomatski destilacijski enoti sta dodajanje presežka natrijevega hidroksida in parna destilacija avtomatizirana postopka.
Proceed according to 5.3.1 or 5.3.2.
Nadaljuje se v skladu s točko 5.3.1 ali 5.3.2.
Titrate the excess sulphuric acid in the collecting flask with sodium hydroxide solution (3.10 or 3.11) depending on the concentration of the sulphuric acid used, until the end-point is reached.
Presežek žveplove kisline v zbirni bučki se titrira do ekvivalentne točke z raztopino natrijevega hidroksida (3.10 ali 3.11) glede na koncentracijo uporabljene žveplove kisline.
Titrate the contents of the collecting flask with the hydrochloric acid standard volumetric solution (3.19) or with the sulphuric acid standard volumetric solution (3.6) using a burette and read the amount of titrant used.
Vsebina zbirne bučke se titrira s standardno volumetrično raztopino klorovodikove kisline (3.19) ali standardno volumetrično raztopino žveplove kisline (3.6), pri čemer se uporabi bireta in odčita količina uporabljene titracijske snovi.
When colorimetric end-point detection is applied, the end-point is reached at the first trace of pink colour in the contents.
Pri določanju s kolorimetrično ekvivalentno točko je ekvivalentna točka dosežena pri prvem znaku rožnatega obarvanja vsebine.
Estimate the burette reading to the nearest 0,05 ml.
Volumen birete se odčita na 0,05 ml natančno.
An illuminated magnetic stirrer plate or a photometric detector may aid visualisation of the end-point.
Magnetna mešalna plošča z osvetlitvijo ali fotometrični detektor lahko pripomoreta k določanju ekvivalentne točke.
This can be done automatically using a steam distiller with automatic titration.
Parni destilator z avtomatično titracijo lahko to opravi avtomatično.
Follow the manufacturers' instructions for operation of the specific distiller or distiller/titrator.
Upoštevati je treba navodila proizvajalca za upravljanje specifičnega destilatorja ali destilatorja/titratorja.
When an automatic titration system is used, titration begins immediately after distillation starts and the 1 % boric acid solution (3.18) is used.
Pri avtomatičnem sistemu titriranja se titracija začne takoj po začetku destilacije, uporabi pa se 1-odstotna raztopina borove kisline (3.18).
The pH-meter shall be calibrated properly in the range of pH 4 to pH 7 following normal laboratory pH-calibration procedures.
Ta pH meter se ustrezno umeri med pH 4 in pH 7 z običajnimi laboratorijskimi postopki za umerjanje pH.
The pH end-point of the titration is reached at pH 4,6, being the steepest point in the titration curve (inflection point).
Ekvivalentna točka pH pri titraciji je dosežena pri pH 4,6, ko je naklon titracijske krivulje največji (točka pregiba).
