Automated Biochemistry Analyzer is a very high tech instrument that is at the forefront of all the technology in the world today. Automatic biochemistry analyzers are used in a wide range of applications in our daily lives, such as for medical treatment, as well as for detecting signs of life and so on. Automatic biochemistry analyzers have made a significant contribution in the field of disaster relief as well as in the medical field. Automatic biochemistry analyzer this thing sounds like a particularly high-end atmosphere on the grade, so automatic biochemistry analyzer in the end is a kind of what kind of instrument? Automatic biochemical analyzer working principle and what is its role? Today I will give you a brief introduction to the Automatic Biochemical Analyzer and its related information.
What is a fully automated biochemical analyzer
To understand the fully automated biochemical analyzer and its role and other information, first of all, we must be clear about the concept of fully automated biochemical analyzer, that is, we must know the fully automated biochemical analyzer is a kind of thing, and its basic situation. An automated biochemistry analyzer is an instrument that measures certain specific chemical components in the body fluids of living things, and it is one of the more accurate instruments available for measuring this information. Fully automated biochemistry analyzers are preferred because of their advantages. The main advantages are that it is fast, accurate, and consumes fewer reagents and medicines.
Principle of automatic biochemistry analyzer
Automated analyzer is the original manual process of sampling, mixing, warm bath (37 ℃) detection, results calculation, judgment, display and print results and cleaning and other steps all or part of the automated operation. Today, biochemical tests are essentially automated analyses, and there are fully automated biochemical analysis systems designed for large or very large clinical and commercial laboratories, which can be configured in any configuration to suit the laboratory's testing volume.
Whether it is today's fastest running (9600Test/h) modular fully automated biochemistry analyzer, or the original manual operation used for colorimetry photoelectric colorimeter, the principle of its use of spectroscopic technology in the absorption spectrometry. It is the most basic core of biochemistry.
Uses of automatic biochemical analyzers
Since the automatic biochemical analyzers have so many advantages, so it is natural that there are many uses. Summarize the main three: the first is applied to family planning services; the second is applied to the detection of epidemic prevention stations; the third is applied to the size of the hospital. The experiment of automatic biochemical analyzer greatly reduces the workload of these places and improves work efficiency.
Automatic biochemical analyzer determination requirements
1. Samples: serum, urine, cerebrospinal fluid.
2. Reagents: single reagent, double reagent
3. Dual wavelength: two wavelengths consisting of the main wavelength and the sub-wavelength. It can eliminate the interference in the detection process.
4. Calibrators (standards): to compare the concentration of unknown samples
5. Quality control products: used for biochemistry instrument in the daily work of the instrument, reagents and other aspects of the state of the monitoring.
Automatic biochemistry analyzer method
1. The endpoint method (endessay) is completely transformed into a product, no longer react to reach the end point, take the absorbance of the end point of the reaction to calculate the concentration of the substance being measured. Biochemical testing in addition to enzymes and BUN, CRE, almost all use the endpoint method for detection.
1). One-point endpoint method: take the absorbance of a point when the reaction reaches the endpoint to calculate the result.
2). Two-point endpoint method: Take the absorbance of one point when the reaction has not yet started, and then take the absorbance of the second point when the reaction reaches the endpoint. Calculate the result by subtracting the difference between the absorbance of the first point and the absorbance of the second point. Mainly used to deduct reagents and sample blanks. Ensure the accuracy of the results. General double reagent.
2. Fixed-time method (two-point method): is to take the difference between the two points still in the reaction to calculate the results. The two points are neither the beginning nor the end of the reaction. It is mainly used to detect some non-specific items, such as creatinine.
3. Continuous monitoring method (kinetic method, rate method): is in the determination of enzyme activity or enzyme metabolites, continuously take the reaction curve is linear change in absorbance value (△; A/min) to calculate the results. The difference in absorbance between the points in the linear time of the reaction is zero, so it is also called a zero-level reaction.

Automatic biochemical analyzer instrument purchase
Medical units at all levels to buy ACA instruments, the main should be the following considerations: the applicability of the model; performance-price ratio; reagent openness; regional differences; after-sales technical support. Among them, the applicability of the model refers to the purchase of units should be in accordance with the actual situation, choose slightly larger than the current workload requirements of the ACA system, in order to adapt to the requirements of the future development of the unit, and at the same time to consider their own economic strength, and strive to one-step, in the instrument's life cycle of 7-8 years will not be eliminated, which also reflects the performance-price ratio of the requirements. For example, all kinds of hospitals should purchase ACA with 1000 tests/hour model, or can be subsequently expanded to more than 1000 tests/hour to meet clinical needs. Regional differences and after-sales technical support, these two issues are wide-ranging, it is not good to generalize, the main consideration should be: the sales of the model in the region, the number of existing similar, the same type of machine, as well as the reputation of the seller and manufacturer. The authors believe that large, medium-sized cities, sales, agents are more concentrated, maintenance and follow-up support can be guaranteed, can focus on the consideration of the purchase of better performance and price of the instrument, while small cities, townships and medical units should be considered to choose a combination of multi-module, can be used independently of the instrument. In case part of the module failure, the remaining modules can still operate normally to protect the normal development of scientific research and medical treatment. Of course, the purchase of the instrument should pay attention to the independence of the modules is good, the common module is simple enough, not easy to fail, experience tells us that the modular ACA common part of the less, the greater the possibility of independent operation.
The purchase of the instrument is a complex project, each unit should be carefully researched, open bidding, do not bring unnecessary losses due to small losses.
Editor's summary: The above is the automatic biochemical analyzer determination requirements and methods of knowledge, I hope to be able to help friends with this need! For more information, please continue to pay attention to our website, the follow-up will present more exciting content.
