As the core equipment of modern medical laboratories, biochemical analyzers are widely used in clinical testing, scientific research and industrial testing. Its efficient and accurate detection capabilities provide important support for disease diagnosis and treatment. This article will introduce the basic operation methods of biochemical analyzers in detail to help users quickly master the use process of the equipment.
1. Power on and preheating
Before using the biochemical analyzer, you must first ensure that the device is connected to the power supply and is in a stable state. After powering on, the instrument usually needs to be preheated for a period of time (about 15-30 minutes) to reach the optimal working temperature. During the preheating period, the operator can prepare reagents and process samples to improve the detection efficiency.
2. Reagent preparation and loading
The biochemical analyzer relies on specific reagents for detection, and the operator needs to select the appropriate reagent kit according to the detection project. The following points should be noted when loading the reagent:
Make sure the reagent is within the validity period and stored in accordance with the instructions.
Load the reagents in the order specified by the instrument to avoid confusion.
Check the sealing of the reagent bottle to prevent contamination or volatilization from affecting the test results.
3. Sample processing and loading
Sample processing is a key step in the test. The operator needs to ensure that the sample has no interfering factors such as hemolysis, lipemia or icterus. Before loading, the sample needs to be packaged or diluted according to the instrument requirements. When loading the sample, pay attention to:
Use disposable tips or pipettes to avoid cross contamination.
Load the sample in the order of sample numbers specified by the instrument to ensure data traceability.
Check whether the sample volume is sufficient to avoid test failure due to insufficient samples.
4. Parameter setting and test start
In the instrument control interface, the operator needs to select the corresponding test program according to the test item and set relevant parameters (such as wavelength, reaction time, etc.). After confirming that the parameters are correct, start the test program. The instrument will automatically complete sample incubation, reaction and detection, and generate a data report.
5. Result analysis and maintenance
After the test is completed, the operator needs to review the results to ensure data accuracy. If abnormal results are found, they should be re-checked or the cause should be investigated in time. In addition, regular cleaning and maintenance of the instrument (such as replacing the colorimetric cup and cleaning the pipeline) is the key to ensuring long-term stable operation of the equipment.
Mastering the correct operation method of biochemical analyzer can not only improve the detection efficiency, but also ensure the reliability of the results. For foreign trade enterprises, being familiar with the operation of equipment can help better serve international customers and enhance market competitiveness.
