Biochemistry analyzer, one of the most commonly used medical equipment in the daily work of pet hospitals. So how to choose a biochemical analyzer, what factors should be considered?
Many high-tech technologies are constantly being introduced into the equipment, therefore, it's better to choose new model equipment as much as possible. When choosing biochemical analyzers, it is the best choice to choose the right model according to the actual work of the user. When choosing a biochemical analyzer, there are several parameters to consider.
One of the most crucial parameter of biochemical analyzer is the accuracy of data. The accuracy of result is closely related to the core technology behind the medical equipment. The blood analyzers can be divided into two kinds-the wet analyzer and dry analyzer. Wet biochemistry means that all reactions are in liquid. The dry type is a detection method in which the liquid in the sample to be tested is used as a reaction medium, and the analyte is directly reacted with the dry powder reagent solidified on the carrier.
2. Small Blood Sample
In animal diagnosis, the process of collecting blood will be difficult because of the pets are too small. Or some strange pets have less blood, all these will add more difficulty to the diagonisis of pets. Therefore choosing a blood chemistry analyzer which requires small blood sample is better.
The test speed is one of the important parameters for the users to select the biochemical analyzers, which reflects the ability of the instrument to process the sample per unit time, and is often expressed by the number of tests completed per hour.
It should be noted that when the biochemical analyzer is equipped with an electrode part, the test speed can be calculated independently, especially when comparing multiple devices, the biochemical part and the electrode part should be compared separately. There is no uniform calculation method for the test speed of the biochemical analyzer.
The speed indicated by the manufacturer is for reference only. In actual work, the factors affecting the test speed also include the time required for the instrument to automatically clean the pipeline or the completion time of the first inspection result. Generally, the cleaning time required for small equipment is short.
4. Optical parameters
In addition to the characteristics of the spectroscopic technology, the number of monochromatic light wavelengths (or color filters) of the instrument in a certain wavelength range should meet the needs of laboratory testing work, usually in the wavelength range of 300 to 800 nm.
The number of fixed wavelengths should be more than 11. Instrument detector absorbance value range. When it reaches 2.0 or above, it can meet the requirements of clinical practice. The optical cell diameter can directly affect the effective range and resolution of the absorbance value. When the optical path is long, the sensitivity and precision are easy to be obtained, but the reagent and sample volume (minimum reaction volume) will increase.
5. Reagent position and sample loading
The automatic biochemical analyzer currently used in clinical laboratories generally adopts multi-channel analysis. The reagent position should meet the needs of routine biochemical test items. When the laboratory uses double reagents, the reagents of the instrument are required.
The position should be increased accordingly. If the reagent needs to be loaded during the operation of the instrument, most devices require a special reagent loading procedure and the reagent loading is completed in the measurement gap.
The sample loaded on the biochemical analyzer can be sample tray or sample holder. The sample tray can be loaded with more samples at one time, mostly for small and medium-sized instruments. The sample loading through the sample rack is flexible and suitable for laboratory automation of sample transmission. It is the main loading sample form of large biochemical analysis equipment. For ease of use, many instruments have dedicated channels or sample locations for emergency sample testing, as well as dedicated locations for calibrators and controls.
Once In the event of an emergency, the biochemical analyzer often fails to play its role, delaying the hospital and the patient's condition. After the user has experienced operational problems or failures, the 24-hour after-sales team can respond in time and provide services to the customer to solve the problems of the biochemical analyzer customer.
Various factors need to be considered when choosing a reliable supplier, the technical parameters and the after-sale service of suppliers are also vital.
