Technical field
The utility model relates to a kind of glycosylated hemoglobin analyser, important devices especially wherein: the ultraviolet light chromatographic detector.
Background technology
Be used to detect the glycosylated hemoglobin analyser of human diabetes controlling index, it is light, mechanical, electrical integrated instrument, mainly by infusion pump, liquid control valve, chromatography column, ultraviolet light chromatographic detector, circuit control panel and compositions such as control and analysis software, wherein, the ultraviolet light chromatographic detector is one of them important devices, and its technical feature has determined the basic mechanical design feature of analyser.Though existing chromatographic detector is widespread use on various chromatographic analyzer of liquid phase, also have some shortcomings.For example, in existing chromatographic detector, in case liquid is drained in the liquid road, perhaps before instrument uses first, pipeline inside is full of air, must be full of the pipeline of whole analyser inside and the liquid line of chromatographic detector, the gas in the emptying pipeline with analytical reagent.But remaining bubble in the liquid line of chromatographic detector often needed could get rid of totally to dozens of minutes in tens minutes, and is both time-consuming, wasted a large amount of reagent again.Again for example, the luminosity of the luminotron of existing chromatographic detector stability excessively relies on the luminous constancy of element, makes the element cost high.
Summary of the invention
The utility model is the improvement at above-mentioned existing chromatographic detector.Concrete scheme is:
A kind of ultraviolet light chromatographic detector of glycosylated hemoglobin analyser comprises photodiode 1, ultraviolet LED 2, luminescence-utraviolet management and control system circuit board 4 and detects the liquid analysis path; Wherein detecting the liquid analysis path comprises: detect liquid intake line 17, detect liquid vertical duct 14, detect spectrum pipeline 8, detect liquid vertical duct 22, detect liquid output pipe 7; Wherein, detect liquid intake line 17 and be positioned at the detecting device below, detect liquid output pipe 7 and be positioned at the detecting device top; The angle α scope that detects liquid output pipe 7 and detection liquid intake line 17 is at 120 ° ~ 240 °; The angle β scope that detects liquid output pipe 7, detection liquid intake line 17 and detection spectrum pipeline 8 is between 90 ° ± 45 °; Described pipeline 7,8,14,17 is identical with 22 diameters, and the pipeline diameter scope is at 0.5 ~ 2mm; Described detection liquid vertical duct 14 and pipeline 22, its upper extreme point is not higher than the edge that is horizontal pipeline.If if liquid has carried bubble in the chromatographic detector pipeline, can be easy to get rid of.
What above-mentioned ultraviolet LED 2 adopted is that lighting angle δ is 50 ° ~ 140 ° a ultraviolet LED, the photodiode 1 that install its side can receive the ultraviolet ray intensity that ultraviolet light-emitting diodes 2 sends, its signal output is delivered in the luminescence-utraviolet management and control system circuit board 4 as feedback signal, when factors such as the aging decay of voltage, temperature or UV-light luminous pipe change, can control the constant of ultraviolet LED 2 luminous intensities preferably, in order to the luminous intensity of stabilized illumination pipe.Like this, because lighting angle is greater than 50 degree, so, control highly sensitively, effective, can make the luminous intensity maintenance of luminescence-utraviolet pipe constant, avoided the luminous constancy of excessive dependence element.
