    • A method for correcting an instrumental error due to wavelength error of a spectroscope of an optical analyzer for measuring an optical density reflected from or transmitted through a dry analysis element. One standard color plate having a standard optical density OD.sub.ST is measured by an optical analyzer to be corrected to obtain an measured value OD.sub.M. A measured optical density OD.sub.S of the element applied with a sample through the optical analyzer to be corrected is corrected by using a ratio of OD.sub.M /OD.sub.ST to obtain a corrected measured value OD.sub.C of the sample. The standard color plate to be used contains an indicator dye contained in the non-reacted dry analysis element or a dye having an absorption spectrum same as or similar to that of the indicator dye in the measurement wavelength range. Another correction method in consideration of a layer coefficient of a dry analysis element is also provided.
    • 一种用于校正由用于测量从干分析元件反射或透过干光分析元件的光密度的光学分析仪的分光镜引起的波长误差的仪器误差的方法。 通过光学分析器测量具有标准光密度ODST的一个标准色板以进行校正,以获得测量值ODM。 通过使用ODM / ODST的比例来校正通过待校正的光学分析器施加样品的元件的测量光密度ODS,以获得样品的校正测量值ODC。 所使用的标准色板包含未反应干燥分析元件中所含的指示剂染料或在测量波长范围内具有与指示剂染料相同或类似的吸收光谱的染料。 还提供了考虑干分析元件的层系数的另一校正方法。
