Automatic Spectrophotometer JK WFH-203C

一、Overview

The UV Analyzer WFH-203C, also known as an Ultraviolet Analyzer, Food Packaging Fluorescent Substance Detector, Paper Fluorescent Substance Detector, Fluorescent UV Rapid Detector, Fluorescent Brightener/Edible Fungus, Toxin – type Fluorescent UV Rapid Detector, Fluorescent Brightener, Edible Fungus, Toxin – type, Nitrofurazone Metabolite UV Rapid Detector, Darkroom – type Paper UV Analyzer, Fluorescent Substance Detector, and UV Detector.

二、Principle and Scope of Use

For fluorescence analysis: Fluorescent substances are compounds with luminescent properties. When fluorescent substances are irradiated by ultraviolet rays, the energy of the ultraviolet rays excites the electrons of the molecules to jump to a high electronic energy level, and then the substances are in an excited state. After this energy is absorbed, the molecules of the fluorescent substances start to return from the excited state to the ground state. During this process, energy will be released, and this energy will be emitted in the form of fluorescence. It is mainly applied in: bio – genetic engineering, molecular genetics, medical and health care, biological products, drug research, health and epidemic prevention, dye chemical industry,

petrochemical industry, textile industry, political and legal departments, cultural relics and archaeology departments. All departments that need to carry out fluorescence analysis and verification can use it.

1. In scientific experimental work, it is a routine instrument for detecting many main substances such as proteins and nucleotides.

2. In drug production and research, it can be used to check the quality of various fluorescent drugs such as hormones, alkaloids, and vitamins. It is especially suitable for thin – layer analysis, paper layer analysis spot detection.

3. In the chemical industries such as dyes, coatings, rubber, and petroleum, it can be used to determine various fluorescent materials, fluorescent indicators and additives, and identify different types of crude oils and rubber products.

4. In the textile and chemical fiber industry, it can be used to identify the quality of finished products of different types of raw materials such as wool, real silk, man – made fibers, and cotton synthetic fibers.

5. In the grain and oil, vegetable, and food sectors, it can be used to check the quality of toxins (such as aflatoxins, etc.), food additives, deteriorated vegetables, fruits, cocoa butter, chocolate, fat, honey, sugar, eggs, etc.

6. In geology, archaeology and other departments, it can play a role in discovering various minerals and judging the authenticity of cultural relics and fossils.

7. In the public security department, it can be used for fingerprint detection, secret writing identification, etc.

8. For on – site batch rapid detection in fields such as agricultural product and food processing, storage, customs entry – exit, animal husbandry, scientific research, and circulation, or for quality control of food in supermarkets and shopping malls.

三、Main Features and Parameters

It adopts a fully enclosed environmental – friendly darkroom design made of high – strength ABS material. Built – in UV lamps allow use in bright environments.
Operation ports on both left and right sides enable moving samples inside the darkroom (no need to adjust the UV lamp angle inside).
A standard camera hole is added on the top for various digital cameras and mobile phones to capture detection results, save data, and record in real – time.
