Transfer the specimen to a Kjeldahl digestion flask.
Preskusni primerek se vloži v Kjeldahlovo razklopno bučko.
To the specimen weighing at least 1 g contained in the digestion flask, add, in the following order, 2,5 g potassium sulphate, 0,1-0,2 g selenium dioxide and 10 ml sulphuric acid (relative density at 20 °C: 1,84).
Primerku mase najmanj 1 g se nato v bučki za razklop dodajo v naslednjem zaporedju: 2,5 g kalijevega sulfata, 0,1-0,2 g selenovega dioksida in 10 ml žveplove kisline (z relativno gostoto pri 20 °C 1,84).
Heat the flask, gently at first, until the whole of the fibre is destroyed, and then heat it more vigorously until the solution becomes clear and almost colourless.
Bučka se začne segrevati, sprva počasi, dokler se vlakna v celoti ne razgradijo, nato pa močneje, dokler se raztopina ne zbistri in postane skoraj brezbarvna.
Heat it for a further 15 minutes.
Segrevanje se nadaljuje še nadaljnjih 15 minut, nakar se bučka z vsebino ohladi.
Allow the flask to cool, dilute the contents carefully with 10-20 ml water, cool, transfer the contents quantitatively to a 200 ml graduated flask and make up to volume with water to form the digest solution.
Raztopina se pazljivo razredči z 10 - 20 ml vode, ponovno ohladi, kvantitativno prenese v merilno bučko prostornine 200 ml, dolije se ji voda do oznake, da nastane nasičena raztopina.
Place about 20 ml of boric acid solution in a 100 ml conical flask and place the flask under the condenser of the Kjeldahl distillation apparatus so that the delivery tube dips just below the surface of the boric acid solution.
V erlenmajerico s prostornino 100 ml se nalije približno 20 ml raztopine borove kisline. Erlenmajerica se podstavi pod kondenzator Kjeldahlovega destilacijskega aparata tako, da je dovodna cev v erlenmajerici potopljena tik pod površino raztopine borove kisline.
Transfer exactly 10 ml of digest solution to the distillation flask, add not less than 5 ml of sodium hydroxide solution to the funnel, lift the stopper slightly and allow the sodium hydroxide solution to run slowly into the flask.
V destilacijsko bučko se vlije natanko 10 ml nasičene raztopine, in v lij na aparatu se doda najmanj 5 ml raztopine natrijevega hidroksida, zamašek se rahlo privzdigne in pusti, da raztopina natrijevega hidroksida počasi steče v bučko.
If the digest solution and sodium hydroxide solution remain as two separate layers, mix them by gentle agitation.
Če nasičena raztopina in raztopina natrijevega hidroksida ostaneta ločeni v dveh plasteh, ju je treba pomešati z rahlim stresanjem.
Heat the distillation flask gently and pass it into steam from the generator.
Sledi počasno segrevanje destilacijske bučke in dovajanje pare iz generatorja.
Collect about 20 ml of distillate, lower the conical flask so that the tip of the delivery tube of the condenser is about 20 mm above the surface of the liquid and distil for 1 minute more.
V erlenmajerici se zbere približno 20 ml destilata, nakar se jo spusti toliko, da je vrh dovodne cevi erlenmajerice približno 20 mm nad površino tekočine, nakar se destilacija nadaljuje še 1 minuto.
Rinse the tip of the delivery tube with water, catching the washings in the conical flask.
Vrh dovodne cevi se spere z vodo, tako da se izpiralna raztopina lovi v isto erlenmajerico.
Remove the conical flask and replace it with another conical flask containing roughly 10 ml of boric acid solution and collect about 10 ml distillate.
S priprave za destilacijo se umakne erlenmajerica in namesto nje nastavi druga, v kateri je približno 10 ml raztopine borove kisline. V to erlenmajerico se pridobi okoli 10 ml destilata.
Titrate the two distillates separately with 0,02 N sulphuric acid, use the mixed indicator.
Oba destilata se titrirata ločeno z žveplovo kislino 0,02 N, pri čemer se uporabi mešani indikator.
Record the total titre for the two distillates.
Zabeležiti je treba celotno titracijsko vrednost vsakega destilata.
If the titre for the second distillate is more than 0,2 ml, repeat the test and start the distillation again using a fresh aliquot of digest solution.
Če je titracijska vrednost drugega destilata višja od 0,2 ml, se celotni postopek destilacije ponovi, pri čemer se začne destilirati nov odmerek nasičene raztopine.
Carry out a blank determination, i.e. digestion and distillation using the reagents only.
Narediti je treba tudi slepi preskus, torej razkroj in destilacijo samo z uporabo reagentov.
