标准范围

50%己内酰胺水溶液的吸光度在390 nm波长和50 mm光程长度下进行光谱测量。将测量的吸光度乘以等于150的常数因子，以哈森单位表示结果。该系数源自铂钴标度稀释标准溶液的吸光度测量。

The absorbance of a 50 % aqueous caprolactam solution is spectrometrically measured at a wavelength of 390 nm and an optical path length of 50 mm. The result is expressed in Hazen units by multiplying the absorbance measured by a constant factor equal to 150. This factor is derived from measurements of absorbance of diluted standard solutions of platinum-cobalt scale.
