Problems solved by technology

Food safety detectors on the market use LED lamp beads as the detection light source, but the light source of this instrument has a half-life, and the brightness of the light source will slowly decay along with the change of time. With the change of time and the fluctuation of the light source voltage, the instrument The test results vary greatly; the optical paths of the instrument are also very different, and the test results obtained by the same concentration of reagents at different test positions are quite different, which causes confusion and inaccurate test results. It has affected the promotion and application of ELISA food safety detectors

Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0014] see Figure 1~4 , in the embodiment of the present invention, a kind of food testing special experiment operating table, comprises casing, control circuit and optical path system, and control circuit and optical path system are installed in casing, and the optical path system in casing adopts halogen lamp as light source, And the light source is divided into a detection light path and a monitoring light path. The detection light path is divided into several detection light paths. On the photocell of the D detection circuit board, the detection optical path includes a chip U1, a resistor R1, a capacitor C1, a triac VS and a sensor PIR, and the pin 1 of the chip U1 is respectively connected to a resistor R12 and a capacitor C8, a capacitor C10 and a capacitor C11, The pi...

Abstract

The invention discloses an experiment operating platform special for food detection. The experiment operating platform special for food detection comprises a machine shell, a control circuit and a light path system; the control circuit and the light path system are arranged in the machine shell; the light path system in the machine shell adopts a halogen lamp as a light source and the light source is divided into a detection light path and a monitoring light path; the detection light path is divided into a plurality of detection branched light paths; the monitoring path is one path; the detection branched light paths lead to detection samples and are irradiated on a photocell of an A / D detection circuit board through light path condensation and according to the emergent light intensity of the detection sample; the detection light path comprises a chip U1, a resistor R1, a capacitor C1, double-way controllable silicon VS and a sensor PIR. According to the experiment operating platform special for food detection, the change of the light source intensity can be monitored in real time, stable detection data can be acquired when a power supply is unstable or within short boot time, and the troubles that an instrument needs to be checked at regular intervals and the instrument is warmed during starting-up are avoided.

Description

technical field [0001] The invention relates to an operation table, in particular to an experiment operation table specially used for food testing. Background technique [0002] Food safety is a major issue related to people's livelihood. In recent years, food crises have occurred frequently, and the public has become more and more distrustful of domestic food. Comprehensive food safety testing has been a topic that has attracted the attention of the public for a long time. At present, gas phase and spectroscopic methods are usually used for food inspection. Due to the high cost of purchasing equipment related to these two methods, the inspection method is time-consuming and laborious, and the inspection cost is too high, so the promotion of gas phase and spectroscopic equipment is largely limited. application. However, the food safety comprehensive detector using the mature enzyme-linked immunosorbent immunoassay (ELISA) method and the ELISA kit for inspection is low in c...
