双波长分光光度法近几年来在测定混合物及有干扰物质的成分时应用较多,现在已发展三波长及多波长测定法。复方结核胺片是异菸肼及胺苯硫脲等复合制剂,以紫外吸收光谱看出异菸肼最大吸收处胺苯硫脲有影响,采用双波长分光光度法的原理,用单波长分光光度计进行试验,能排除胺苯硫脲的干扰,并得到较好效果。本文将测定结果介绍如下: 一、双波长分光光度法简介双波长分光光度法的原理是基于选择以欲测定组分的任意波长λ_1为基础,与其他
Dual-wavelength spectrophotometry has been used more often in the determination of mixtures and interfering substances in recent years. Three-wavelength and multi-wavelength assays have now been developed. Compound nifedipine is isoniazid and amine phenylthiourea and other composite formulations to UV absorption spectra of isoniazid maximum absorption of amiloride have an impact, the principle of dual-wavelength spectrophotometry, single-wavelength spectrophotometry The test, can eliminate the interference of amiloride and get better results. This article will determine the results are described below: First, the two-wavelength spectrophotometry Introduction The principle of dual-wavelength spectrophotometry is based on the choice of components to be determined arbitrary wavelength λ_1 as the basis, and other
