1873Chem. News 11 July 13/2 Whether the Nesslerising takes a couple of minutes, or whether it takes an hour, is a matter of vital importance to those persons who are working the ammonia process of water analysis. 1881Nature XXIII. 403 Converted into ammonia, which is estimated by nesslerising. 1884Jrnl. Amer. Chem. Soc. VI. 122 Such a tube was found..to be unsuitable for comparison with the color of Nesslerized liquids. 1890Amer. Chem. Jrnl. XII. 426 Standards and distillates are made ready for nesslerisation during the day, and all stand on the same table overnight. In the morning they are nesslerised and compared. 1916Jrnl. Biol. Chem. XXVI. 473 It was hoped that it would be possible to Nesslerize directly the ammonia produced by the destructive digestion of the urine. Ibid. 475 This sediment does not interfere with the Nesslerization of the ammonia, but it must be removed before the color comparison is made. Ibid. 481 It is better when working in urine to dilute the final Nesslerized solution to 200 cc. instead of to 100 cc. 1956Jrnl. Lab. & Clin. Med. XLVII. 645 In one the clot is dried and weighed to the nearest microgram; in the other it is nesslerized and assayed colorimetrically. Ibid. 646 If a microbalance is not available, the fibrin may be estimated by digesting it in sulfuric acid and hydrogen peroxide, nesslerizing, and determining the color density. 1964Oceanogr. & Marine Biol. II. 148 They determine ammonia in the digest by Nesslerization. 1970Nature 12 Sept. 1136/2 l-Glutaminase and l-asparaginase assays were performed..as previously described except that the colour formed by nesslerization of ammonia was measured 1–3 min after addition of Nessler's reagent. |
