Abstract: Improvements in and relating to devices for receiving liquid samples A device for receiving a liquid sample may form part of a micro sampling head for an instrument such as a spectrophotometer. The device receives a liquid sample to be analyzed by a process involving the passing of electromagnetic radiation through the sample, and comprises a light inlet guide (20) for directing electromagnetic radiation into the sample, a light receiving element (23) situated in an opposed relationship to the guide and spaced from the guide by a fixed distance to define a fixed path length gap (21), which is, in use, filled with the sample. In use, radiation is passed from the light inlet guide to the light receiving element (23), and the path length of radiation through the sample is defined by the gap (23). The device is open or openable to allow a droplet of sample to be deposited directly in the gap.

Abstract translation: 用于接收液体样品的装置的改进和涉及用于接收液体样品的装置可以形成诸如分光光度计的仪器的微采样头的一部分。 该装置通过涉及通过样品的电磁辐射的过程接收待分析的液体样品，并且包括用于将电磁辐射引入样品的光入口引导件（20），位于相对的位置的光接收元件（23） 与引导件的关系，并与引导件间隔一定距离，以限定在使用中填充样品的固定路径长度间隙（21）。 在使用中，辐射从光入口引导件传递到光接收元件（23），并且通过样品的辐射的路径长度由间隙（23）限定。 该装置是打开的或可打开的，以允许一滴样品直接沉积在间隙中。
