报道双波长法测定口腔溃疡膜中二组分的含量。盐酸金霉素的测定波长为230nm,参比波长为307nm;盐酸达克罗宁的测定波长为283nm,参比波长为264.5nm。方法回收率101.5%±0.64%(盐酸金霉素),101.6%±0.44%(盐酸达克罗宁)。
Report dual wavelength method for determination of oral ulcer membrane content of two components. The determination of chlortetracycline hydrochloride has a wavelength of 230 nm and a reference wavelength of 307 nm; the determination wavelength of dacronine hydrochloride is 283 nm and the reference wavelength is 264.5 nm. The method recovery was 101.5% ± 0.64% (chlortetracycline hydrochloride), 101.6% ± 0.44% (dacronine hydrochloride).
