以氢溴酸－冰醋酸为裂解剂，对Ｎ－亚硝基化合物进行特异性化学裂解，释放的ＮＯ采用化学发光检测器检测，将ＮＯＣ作为一类化合物进行检测。以氨基磺酸破坏ＮＯ－２，离子交换树脂Ｄｏｗｅｘ１Ｘ８去除ＮＯ－３，盐酸－冰醋酸消除热和酸不稳定性化合物。这一方法用于食品检测可提供ＮＯＣ总量的信息
N-nitroso compounds were specifically chemically cleaved with hydrobromic acid-glacial acetic acid as cleavage reagent. NO released was detected by chemiluminescence detector and NOC was detected as a class of compounds. NO-2 was destroyed by sulfamic acid, and NO-3 was removed by ion exchange resin Dowex 1X8. Hydrochloric acid-acetic acid was used to eliminate heat and acid-labile compounds. This method for food testing provides information on the total amount of NOCs
