Description
Technical field
This utility model relates to a kind of detecting instrument, specifically a kind of garden stuff pesticide residue detector.
Background technology
Pesticide residues are not only great Quality Safety Problems of Agricultural Products, more relate to the social problem of the aspects such as modern agricultural development, construction of legal rules and laws, oversight mechanism and whole society's consumption idea. Pesticide residues are the inevitable phenomenons after dispenser, environment not only can be caused great pollution by extended residual pesticide in vegetables and fruits, air, soil and water source, meanwhile, by the enrichment of food chain, residual pesticide also can enter human body thus human body is produced various harm. Therefore, pesticide residues are carried out in time, detection accurately is the necessary means ensureing human health and sustainable development with monitoring.
In numerous detection techniques, chromatograph detection technique, owing to having good detection sensitivity, accuracy and elaboration, becomes the Analytical Techniques of Pesticide Residues being most widely used. But its expense is relatively costly, and pre-treatment step is loaded down with trivial details, solvent-oil ratio is big, and length consuming time, it is necessary to special instrument and equipment and operator just seems when a large amount of samples are carried out low cost rapid screening by needs unable to do what one wishes. In the last few years, some relatively easy, quick and cheap detecting devices are developed in succession, but these devices are mostly in indoor use, and the requirement using environment is comparatively strict and environmental factors is especially sensitive, and testing result is unstable, and error is bigger.
Utility model content
The purpose of this utility model is just to provide a kind of garden stuff pesticide residue detector, to solve the problem that existing instrument cost is high, detecting step is loaded down with trivial details, testing result precision is low.
This utility model is achieved in that
A kind of garden stuff pesticide residue detector, being provided with human-computer interaction interface and sample detection zone on machine case body, described sample detection zone includes some detection grooves, and the arrangement of described detection groove is in a row, described sample detection zone is provided with temperature chamber, and described detection groove is arranged in described temperature chamber;Being covered with cover plate above described sample detection zone, described cover plate is hinged on described machine case body, is provided with the sealing plate for sealing detection groove on the inner plate surface of described cover plate, is provided with a circle sealing strip on described cover plate along its edge; End face at described machine case body is provided with solar panel, and described solar panel is connected with the accumulator being arranged within described machine case body.
Described machine case body is provided with electric source line interface, on and off switch and USB interface.
Described human-computer interaction interface includes display screen and operation button.
The detection method that this utility model adopts is enzyme inhibition rate method, the main specificity suppression reaction according to Organophosphorus and carbamate pesticides class pesticide to enzyme acetylcholine, by measuring whether the Organophosphorus and carbamate pesticides pesticide residue in suppression ratio judgement sample exceeds standard.
During use, turn on the power switch, make instrument enter and treat machine testing state, then preparation compares liquid to be measured and sample liquid to be measured, liquid to be measured for the comparison prepared and sample liquid to be measured is separately added in cuvette, and is quickly put into by the cuvette filling liquid to be measured in detection groove, cover cover plate, make the sealing plate on cover plate inner plate surface seal by cuvette oral area, make the sealing strip of side edge thereof be sealed at the place of covering of cover plate with machine case body, to avoid external environment condition that testing result is impacted. The temperature of temperature chamber being controlled at 37 DEG C, then press measurement key, on display screen, the measurement time starts countdown, after timing, and display screen display suppression ratio. If sample suppression ratio��40%, then this sample is considered as qualified samples; If the suppression ratio of sample is between 40 ~ 50%, then this sample is that suspicious pesticide residues exceed standard sample; If the suppression ratio of sample is more than 50%, then this sample is that pesticide residues exceed standard sample, it was shown that its pesticide residue toxicity exceedes safe defining standard.
This utility model, when detecting, is affected only small by outside environmental elements, can avoid the measurement error that environmental fluctuating causes, and measured value accuracy is high. This utility model is less costly, long service life, simple to operate, instructs without professional person during use; And its volume is little, can be contained in suitcase, it is simple to carry. When this utility model uses out of doors, even if around not having power supply or charger, remaining on and can use, the pesticide residues detecting fruit and vegetable food for plantation out of doors bring great convenience.

Detailed description of the invention
As it is shown in figure 1, this utility model is mainly made up of parts such as machine case body 1, human-computer interaction interface 2, sample detection zone and electrical storage devices.
Machine case body 1 is rectangular box, as in figure 2 it is shown, be provided with electric source line interface 10, on and off switch 8 and for connecting the USB interface 9 of external equipment in the side of casing. Detector of the present utility model can be used alone, it is also possible to being connected on computer by USB interface 9 and use, USB interface 9 can also connect the outut devices such as printer.
Human-computer interaction interface 2 is arranged on the left-half of machine case body 1, is used for inputting and reading data, is made up of display screen and operation button.Display screen is used for showing the data messages such as measurement time, sample number into spectrum, measurement numerical value, accuracy of reading, directly perceived. Operation button is used for inputting instruction, to control detection zone and start, break-off or carry out the operations such as automatic diagnosis.
As it is shown in figure 1, sample detection zone is arranged on the right half part of machine case body 1, including some detection grooves 4, detection groove 4 is divided into left and right two rows, and the cuvette filling reference substance or sample liquid to be measured is placed in detection groove 4. Being provided with light source in detection groove 4, each detection groove 4 is controlled respectively by program, works alone, and will not produce interference each other, can detect multiple sample simultaneously. Sample detection zone is provided with left and right two temperature chambers 11, left bank detection groove be arranged on left side temperature chamber in, the right side list and index survey groove be arranged on right side temperature chamber in, the temperature of temperature chamber 11 controls at 37 DEG C. Above sample detection zone, buckle closure has cover plate 3, cover plate 3 to be hinged on machine case body 1, and it can overturn around jointed shaft, and then open or close detection zone. Being provided with two rectangular seal plates 5 on the inner plate surface of cover plate 3, the width of sealing plate 5 is slightly larger than the width of detection groove 4, and the length of sealing plate 5 is slightly larger than the distribution length of single detection groove 4. Cover plate 3 is provided with a circle sealing strip 6 along the edge of cover plate 3, when cover plate 3 covers on sample detection zone, the contact surface of cover plate 3 and machine case body 1 is sealed tight by sealing strip 6, sealing plate 5 covers on the detection groove 4 of correspondence, so that the cuvette being placed in detection groove 4 is sealed, thus ensure that the sealing that detection zone is good, when detecting, the error that sample can be avoided to be subject to external environmental interference and cause, improves the precision of testing result.
