Based on above-mentioned full-automatic detection apparatus, present invention also offers a kind of fully-automated synthesis method based on Immune scatter turbidimetry, as shown in Figure 6, comprise step:
Step S100, control system control two-dimentional machinery arm, sampling needle are moved to the put area of detected sample, draw detected sample, and move to reaction cup place, added by detected sample in reaction cup;
Step S200, control system load first by the first reagent needles and detect reagent in reaction cup, and start stirring apparatus, stirring reaction cup;
Step S300, after the first detection reagent and detected sample have reacted, control system has loaded the second detection reagent by the second reagent needles in reaction cup, and starts stirring apparatus, stirring reaction cup;
Step S400, after the second detection reagent and mixed liquor have reacted, measured the scattered light intensity of solution in reaction cup by Immune scatter turbidimetry, calculated the content of composition to be measured in detected sample, and waste liquid is discharged;
Step S500, control system start cleaning device, are added by cleaning fluid in reaction cup, and start stirring apparatus, stirring reaction cup, discharges cleaning fluid after completing.
Further, the step of described startup stirring apparatus, stirring reaction cup specifically comprises: the electric motor starting of stirring apparatus, drives magnetic part to rotate, reaction cup internal magnetic field is changed, and then drives magnetic stirring in reaction cup to rotate.By this detection method, the present invention can realize the fully-automated synthesis of specific protein, and can the abundant stirring of realization response cup and cleaning in testing process, can reach extraordinary Detection results and very high detection efficiency.
In order to avoid reagent needles and sampling needle residual liquid and affect subsequent detection, the present invention can to sampling needle, the inside and outside of the first reagent needles and the second reagent needles is cleaned, particularly, after having added detected sample or detection reagent, control system startup connects sampling needle respectively, the corresponding load pump of the first reagent needles or the second reagent needles, draw cleaning fluid and cleaning fluid directly added in sampling needle or the first reagent needles or the second reagent needles, respectively the inside and outside wall of sampling needle or the first reagent needles or the second reagent needles is cleaned with backwashing manner, timely maintenance sampling needle or the first reagent needles or the second reagent needles inside and outside clean, detect reagent or sample carryover after effectively avoiding each detection and affect subsequent detection, improve accuracy of detection.
Below in conjunction with specific embodiment, above-mentioned testing process is described in detail and is illustrated.
First, sample is added.Sampling needle draws sample in the sample position in detected sample region, sample is drawn into inside sampling needle, then the motion of two-dimentional machinery arm is controlled, above reaction cup sampling needle being moved on to one of them passage (such as passage 1), then, the first reagent needles above this passage is controlled by control system, add in the reaction cup of this passage and detect reagent R1, and then control sampling needle and move down into below reaction cup liquid level, in reaction cup, quantitatively sample is added by the accurate control of control system, after adding sample, whole system starts stirring automatically, the sample mixing in reaction cup.
Secondly, detection reagent R2 is added.After adding detection reagent R1 and sample, through the enough reaction time, the second reagent needles that control system controls above two-dimentional machinery arm automatically moves to correct position, add automatically and accurately and detect reagent R2, after having added, control system starts stirring apparatus automatically, and all liq in reaction cup is stirred and evenly mixed.
Moreover system detects sample content automatically.After having added detection reagent R1, sample, detection reagent R2, whole device has detected automatically.Meanwhile, sampling needle returns to initial load position, and return in the process of initial load position at sampling needle, whole device controls automatically, realizes cleaning the inside and outside wall of sampling needle, for sampling is prepared next time.
Finally, cleaning reaction cup.After that Air conduct measurement in above-mentioned steps completes, system can control the cleaning needle above this passage automatically, automatically in the reaction cup of this passage, inject cleaning fluid, by the changes of magnetic field below reaction cup, drive magnetic stirring in reaction cup to rotate, strengthen the cleaning dynamics to reaction cup inside, finally by negative pressure, the waste liquid in reaction cup is discharged again, through the fluid injection too much taken turns, clean, discharge opeing, completes the cleaning to this passage automatically.Meanwhile, after sampling needle returns to initial load position, step one can be repeated to step 3, carry out the detection to next sample, and pick-up unit automatically cleans and can carry out independently of each other with the detection of next sample simultaneously.
In above-mentioned testing process, the application of sample between each passage and cleaning are separate, and such as passage 1 is at application of sample, can clean other passages such as passage 2 grade.Thus, the efficiency of whole pick-up unit is substantially increased.Simultaneously, for each passage, sampling needle, two reagent needles (reagent 1 and reagent 2) and cleaning needle are all provided separately, the loading pipeline of all liq be all separately, separate, thus the cross pollution avoided well between reagent, substantially increase accuracy and reliability that this device detects automatically.
