Ｎ波长分光光度法测定Ｎ组分是一种计算测定法，通过Ｎ波长分光光度法求得的被测组分在吸收峰处的吸光度与单波长法测同量纯组分的吸光度一致。可以消除其他任何有吸收组分在吸收峰处的影响。由于选择测定波长简单、灵活，计算简便、迅速，开拓了分光光度法同时测定混合组分的 The determination of N component by N-wavelength spectrophotometry is a computational method. The absorbance at the absorption peak of the measured component obtained by N-wavelength spectrophotometry is the same as that of the pure component measured by the single wavelength method. The effect of any other absorbed component at the absorption peak can be eliminated. Because of the choice of measuring wavelength is simple, flexible, simple and rapid calculation, opened up the spectrophotometric determination of mixed components
