Embodiment 2

[0052] Water sample testing, the steps are as follows:

[0053] 1. Calibrate the fluorescence photometer on the day of the test:

[0054] (1) Equipped with zero adjustment solution: select a blank cuvette and add 3ml of pure water;

[0055] (2) Equipped with calibration solution: select another empty cuvette, add 3ml of pure water, 20μl of DNA-fluorescent dye and mix well.

[0056] (3) Calibrate the fluorescence photometer: turn on the ON / OFF switch of the instrument, and the main menu (Main Menu) of the instrument will appear:

[0057]

[0058] Press F1 to enter the "Read Sample" window; press F1 to adjust the sensitivity and enter the "ReadSample" window again; press F2 CAL key, insert the zero adjustment cuvette (BLANKcuvette) according to the display screen instructions and press READ. Take out the zero-adjustment cuvette and substitute it into the CAL cuvette; press READ again, and the instrument is calibrated; the fluorescence reading is 1,000AU±5%.

Abstract

The invention belongs to fluorescence detectors, in particular to a portable fluorescence detector. The prior art has the defects of large size, inconvenient carrying and unavailable field detection at any time as required and cannot meet the requirements for environment protection, food sanitation and medical detection. In the portable fluorescence detector, a rear shell plate (16) is provided with a USB (universal serial bus) interface (14) and an RS-232 interface (15); a lower shell body (18) is provided with an external power supply interface (17) and a cell box (19); a bottom plate is provided with an LED light source (11), colored glass (5), a focus lens (4), a sample pool (3), a focus lens (6), a color filter (7) and a solid receiver (8); and a panel (21) is provided with an optical filter socket (22), a display screen (9) and a key (10). The invention has the advantages of convenient carrying, low energy consumption, directly read detection result and convenient data transmission, storage and calculation, and can be used for carrying out field detection as required.

Description

technical field [0001] The invention belongs to a fluorescence detection instrument, in particular to a portable fluorescence detection instrument. Background technique [0002] Environmental protection, food hygiene, and medical testing are major issues related to the survival and safety of human beings, and are major issues of common concern to all mankind. Environmental pollution, water pollution, and food insecurity pose a major threat to human health. Food contains germs, viruses, toxic compounds, and carcinogens, causing the spread and infection of food-borne pathogenic bacteria that are zoonotic, and the frequent occurrence of drinking water and food poisoning emergencies. It is urgent for people to invent a small , Easy to carry, on-site detection sensitive, accurate, fast detection equipment. The fluorescence detection of microorganisms and toxic compounds has become a necessary detection in drinking water, food and environmental safety. The principle of fluoresc...
