2-2. Aflatoxin B1 rapid test strip card
The AF B1 Rapid Test Strip is based on a competitive colloidal gold immunochromatography technique for rapid screening of grain grains containing AF B1. Add the test solution to the sample well on the test paper card, and combine the AF B1 in the test solution with the gold standard antibody on the gold standard pad to form a complex. If the concentration of AF B1 in the test solution is lower than the sensitivity value, the unbound gold standard antibody flow When it reaches the T region, the AF B1-BSA conjugate immobilized on the membrane combines and gradually aggregates into a visible T line; if the AF B1 concentration is higher than the sensitivity value, the gold standard antibody forms a complex and will no longer be combined with The AF B1-BSA conjugate at the T line combines to form a visible T line. The unfixed composite stream passes through the T zone and is captured by the secondary antibody of the C zone and forms a visible C line. The appearance of the C line indicates that immunochromatography occurs, that is, the test paper is effective.
The technical data and diagram of Aflatoxin B1 rapid test strip card as follows:
1. Glassware: beaker, measuring cylinder, dropper, pipette.

2. Accurately add 4 mL of purified water and ethyl acetate to the centrifuge tube, tightly seal the stopper cap, vigorously shake for 5 minutes, and centrifuge at 4000 rpm for 1 minute.
3. Take 2 mL of the supernatant into a small glass with a pipette, and dry the filtrate. Refer to the table and take the corresponding volume of the diluent to reconstitute the bottom of the cup according to the residue limit. This solution is the test solution
Cereal Residue Limit (ppb) 5 10 20 30 40 50 100
Use diluent volume (ml) 0.8 1.6 3.2 4.8 6.4 8 16

How it works
The instrument is the introduction of foreign advanced technology uses high-frequency theory, that is, the instrument has one natural frequency, the measured water content of different things, pass through the sensor into the machine frequency is different from the difference between the frequencies of two, after the frequency-current converter to convert digital display
Instructions for use:
Moisture Meter for contact measuring instruments, measuring the premise that sensitive parts of the sensor (multi-10mm less than in the preceding paragraph) with the measured object full access to, in general, the sensor probe into the sensitive areas should be measured as much as possible within the object in order to reduce measurement error.
EUT around the metal if it will lead to measurements are not accurate, and called for sensors sensitive parts of the house should be inserted around the 20cm metals.
1.handheld instruments, the sensor probe body rotation into the socket, appropriated for the switch ON, LED screen displays 0 ± 00.5, such as outside its scope, we should slowly adjust the zero knob, so that figures show that less than that in the 0 ± 00.5 be.
2. according to EUT stall different options:
Millet,Rice,wheat, sold, corn flour, wheat flour, peanut flour, starch,
mung beans, sunflower seeds rice, sunflower seedscorn, Kidney beans, red beans, adzuki bean.Soybean
3. will probe into the measured object, the generation of digital stable, indicating the number of measured values of material moisture. 45 seconds automatically shut down.
4.the digital calibration: Due to a variety of dielectric materials are very different, these stalls for the proposed stalls, such as the use of error can be corrected through traditional methods, such as the measured Reagent water is 5%, with 7 files tests showed values of 4%, counter-clockwise rotating dial allows the display to show 5%, look at dial position is referred to a few at a later time measurement of the same material that choose this gear. If the display value is greater than the actual water content values, the dial clockwise, so that numerical values to the actual water. Similarly, this and the next stall. Since then you can not check.
5. replace the battery:
When the zero knob does not adjust to the 0 ± 00.5 or less or a digital display on the erratic jump, please replace a 9V battery (6F22). Level will be pushed back up the battery back cover to replace a 9V battery, if battery power,
Open the battery cover, took out the battery with a small screwdriver adjustment on the side of a small brass screws (potentiometer) to adjust the case of positive counter-clockwise and vice versa clockwise.
