  A beneficial photometric analytical method is described according to which an effective amount of at least one analytical agent for photometric analysis, is delivered from a support into a liquid sample, and advantageously a mixing action may be provided, by moving a portion of the support in the sample. In accordance with the method, the sample may be in a photometric cell disposed in a photometric instrument for optical analysis, or may be in a photometric instrument cell chamber (or well) normally used for receiving a photometric cell for optical analysis. In accordance with an advantageous feature of the method, the sample may be collected by immersing at least a portion of the photometric cell or the photometric instrument well, in is a bulk volume of the liquid to be analyzed, and the photometric instrument is beneficially waterproof. In accordance with a further aspect, a photometric cell that provides more than one optical path length may beneficially be used, and a particular optical path length selected by rotation of the photometric cell in the cell chamber. Also described is a beneficial photometric apparatus for use with such a photometric cell.

  描述了一种有益的光度分析方法，根据该方法，至少一种用于光度分析的分析剂的有效量从一个支架输送到液体样品中，通过在样品中移动支架的一部分，可以提供有利的混合作用。根据该方法，样品可置于光学分析光度测量仪器中的光度测量池中，或置于通常用于接收光学分析光度测量池的光度测量仪器池室（或井）中。根据该方法的一个有利特征，可通过将至少一部分光度测量池或光度测量仪器井浸入待分析液体的体积中来收集样品，并且光度测量仪器可有效防水。根据另一个方面，可使用提供一个以上光路长度的光度测量池，并通过光度测量池在池室中的旋转来选择特定的光路长度。此外，还介绍了一种与这种光度测量池配合使用的光度测量仪器。

  Semi-quantitative colorimetric analysis of a fibrous matrix disposed on a support, and quantitative analysis of liquid color, are described. Cyanide and a halogenating reagent are reacted to produce a cyanogen halide, and Konig reagents are reacted with the cyanogen halide to yield a colorimetrically analyzable complex. A beneficial photometric method is also described. In addition, a reagent delivery device that includes a beneficial fibrous matrix for rapid delivery of reagents and rapid liquid color analysis, is described.
