摘要： This invention is capable of improving performance of a biochemical analyzer and facilitating the maintenance. A light source includes: a first LED that emits ultraviolet light and a second LED that has a light emission spectrum different from that of the first LED, the first LED and the second LED being disposed in parallel; a reflection surface that is opposite to the first LED and reflects light of the first LED; and a dichroic surface that is opposite to the second LED, reflects light of the first LED, and allows light of the second LED to penetrate. When an optical member including the dichroic surface is made to be the dichroic prism, the reflection surface reflects light of the first LED to the second LED side, and by using light source of a configuration having a light shielding unit between a light emission surface of the second LED and a dichroic prism, entering of a light emitted from the plural LEDs as a one light beam (beam) to an optical system of latter stage of the biochemical analyzer is enabled.

摘要： Accordingly, disclosed are various connectors for connecting a colorimetric sensor array to a sample bottle. These connectors allow the colorimetric sensor array to be attached to a sample bottle after autoclaving, and introduce the headspace gas to the colorimetric sensor array at the appropriate time. Examples of these connectors include (1) a needle based connector that punctures the septum of standard bottle to allow gas flow in a chamber with a colorimetric sensor array, (2) a valve based connector that attaches to a sample bottle and when the valve is opened the headspace gas has a path to diffuse to contact a sensor array, and (3) a connector that includes a breakable seal that when broken puts the headspace gas in contact with the colorimetric sensor array.
