The correct choice of pesticide residue tester
There are many types of pesticide residue detection instruments. You can use them to detect different things. Different instruments are used to detect different things. According to your precise requirements for test results, they can be divided into different categories. Generally, there are the following types:
First, pesticide quick test card
It is detected in the form of a card. It is a fast detector with fast results. It is suitable for low-demand, relatively simple detection. The method is simple and fast. No need to prepare reagents, no professional technical training, improve work efficiency, and save a lot of manpower and material resources. But the results can only be analyzed toxic and non-toxic, no technical participation.
Second, pesticide residue speed tester
This method is widely used, and the detection results are more accurate. It can quickly detect organophosphorus and carbamate pesticide residues in vegetables, fruits, food, tea, water and soil. It is suitable for agricultural testing centers and industrial and commercial centers at all levels. Departments, production bases, farmer's markets, supermarkets, health, environmental protection, schools and other fields. And the benefits are many, first of all, the appearance of the machine is beautiful, and some voice prompts, mainly have the following performance characteristics:
The microcomputer is used for temperature time control with high accuracy.
The instrument stores test data, and the dedicated PC software automatically uploads data, PC management and printing, which is convenient and efficient.
The large screen with backlit Chinese display and voice synchronization prompts are easy to use and require no professionals.
The detection speed is fast, preheating for 10 minutes, and the result is reflected in 3 minutes.
The detection volume is large, 12 channels, and 12 samples can be detected simultaneously.
Use AC and DC power supply, built-in rechargeable battery, can be used indoors, in the field, in the car.
LED digital display, built-in adjustable test 30 ° C ~ 50 ° C ± 0.5 ° C thermostat.
Misoperation prompts the alarm.
Battery low battery alarm.
Small size, light weight and easy to carry.
When the speed test card is warmed up, the instrument enters the standard reaction time, the computer prompts the cover to close, but the operation fails after 5 minutes.
Third, high-speed super large capacity pesticide detector
In this case, the detection result is higher, and it can meet the higher requirements of detection. It can quickly detect organophosphorus and carbamate pesticide residues in vegetables, fruits, grains, tea, water and soil. Level agricultural testing center, industrial and commercial department, production base, farmer's market, supermarket, health, environmental protection, school and other fields. It can detect 96 samples at a time, and is suitable for all levels of industry and commerce, technical supervision, health supervision and other departments, large-scale agricultural batch market, agricultural product planting base and so on. The performance characteristics are similar to those of the second lecture above.
Fourth, food safety testing box
This can be configured according to the detection target requirements, and the following options are generally available:
Pesticide residue rapid test card, nitrite rapid test tube, formaldehyde qualitative test box, formaldehyde semi-quantitative test kit, water injection test strip, total acid rapid test solution in vinegar, free mineral acid speed test in vinegar Paper, soy sauce total acid and amino acid nitrogen rate test solution, fake and inferior taste test liquid, iodized salt containing iodine rapid test solution, tetramine strong rapid qualitative test solution, fluoroacetamide rapid qualitative test solution package, enemy mouse sodium salt Qualitative test solution package, rat drug safety test paper, edible oil acid value, peroxide value test card, edible oil tung oil, hemp oil, croton oil, mineral oil quick test identification reagent, arsenic, mercury detection reagent, cyanide detection Device, cyanide detection reagent, disinfectant effective chlorine speed test card 1 box (package, bag); food center thermometer, acidity meter, methanol speed meter, alcohol meter, conductivity meter 1 (set).
5. Others are tea treasures that measure tea separately, fluorescent whitening instruments for measuring mushrooms, etc.
Generally, these are commonly used, such as gas chromatograph and liquid chromatograph, ultraviolet spectrophotometer, atomic absorption photometer are relatively accurate instruments, but the detection method is cumbersome, the result is slow, it takes several days to see the result. The price is relatively expensive, generally less used, and some provincial professional testing centers are equipped.
