You should add the sample in the distillation vessel first and then add NaOH-solution. In the procedure shown on the video sample will react with NaOH-solution in open and it leads loss of nitrogen in form of ammonia. Also the receiving part should be under the liquid level.
@MicroChemsExperiments3 жыл бұрын
Thank you for your findings. In AOAC, it is not said to keep the receiving part under the liquid level. And in this way, shown in this video, we get the expected results. This is because the loss of nitrogen is negligible. Anyways thanks for your suggestion.

@MicroChemsExperiments3 жыл бұрын
Hadiqa Iqbal, Thank you for your questions and observations. First of all, we used %N determination formula from AOAC 2001.11 method which is modified in two places: 1. we didn't use burette reading of blank (Vb) because we didn't conduct any blank digestion in this experiment. 2. We used additionally Acid Factor (F1) which is not mentioned in AOAC book but used by the FAO method of ''Quality assurance for animal feed analysis laboratories, Page-90''. ***We didn't go for the blank digestion to simplify this method and we conducted several studies in our lab and found that there is no significant different in the protein result when we don't run blank digestion. ***Acid factor is only necessary when you want to titrate with any other acid rather than HCl. So, If you want, conduct a blank digestion along with sample (as it gives more accurate protein result) and substract Blank Burette reading from the Sample burette reading. You can also ignore the acid factor if you always use HCl in the titration. Thank you.
