Chromatographic detector with conical leaded light post

The utility model relates to a device among the chromatographic analyzer, a chromatographic detector with conical leaded light post is at the pipeline front end of luminotron to the reagent route, is equipped with an optical fiber or leaded light post. Carry out the chromatogram at a plurality of wavelength of needs and examine time measuring, can use two or more luminotron chip package at the luminotron of a device, also can with the luminotron of the wavelength of difference when moulding plastics just the encapsulation in a leaded light post. The utility model discloses can obviously improve the effect that assembles of light. 本实用新型涉及种色谱分析仪中的器件，种带有圆锥形导光柱的色谱检测器，是在发光管到试剂通路的管道前端，设有个光导纤维或者导光柱。在需要多个波长来进行色谱检测时，可使用两个或多个发光管芯片封装在个器件的发光管，也可以将不同的波长的发光管在注塑时就封装在个导光柱内。本实用新型可明显提高光的汇聚效果。
