1，Semi-automatic biochemical analyzer should be installed on a smooth, fixed, dust-free working platform at room temperature of 15-30℃ and relative humidity <85%. The power supply of the instrument should be used separately. And need to be equipped with UPS uninterruptible power supply and ground, ground is particularly important. In order to ensure the best working condition of the instrument, it is best to warm up the instrument for 10 min before testing the specimen.
2, semi-automatic biochemical analyzer daily before the start, should do a good appearance check. Inhale distilled water to clean the pipeline and colorimetric pool after power on. Between the two items tested and before shutting down the machine must be cleaned with distilled water to avoid contamination of the colorimetric pool.
To regularly clean the colorimetric pool and pipeline with biochemical cleaning solution. This is because proteins and lipids in the serum tend to adhere to the tubing. Trace of lipid deposition can make the colorimetric pool appears difficult to drive away the bubbles. This leads to errors in test results.
3, because the measurement needs to be the correct choice of pump suction volume. Peristaltic pump itself standard to be completed by inhaling a quantitative liquid. So regular calibration of the peristaltic pump is critical.
4, to often replace the silicone tube connecting the colorimetric pool and peristaltic pump. Its aging will affect the accuracy of the amount of aspirated liquid. If the semi-automatic biochemical analyzer is out of use for a few days, the silicone tube should be removed from the peristaltic pump bracket to keep the silicone tube as flexible as it should be.
5, although after each measurement will inhale distilled water to thoroughly clean the colorimetric pool. But over time, the colorimetric pool will still be difficult to remove the dirt. Therefore, every week to use effective biochemical cleaning solution for cleaning. Do not use acidic or other solutions that will damage the silicone tube to clean.
6, high blood lipid serum and other cloudy serum specimens, can not pass through the colorimetric pool transillumination. It should be re-sampled and tested to ensure the accuracy of the results.
7, long-term use of semi-automatic biochemical analyzer, should pay attention to maintain the light bulb transmittance. Once the adsorption of dust, it will make the light transmission of the optical circuit system to reduce.
To cut off the power in the case, use a soft cloth or skim cotton dipped in alcohol to clean the surface of the bulb. In addition, when replacing the bulb, do not leave fingerprints or other oily substances on the bulb. This is to avoid the bulb heat generated by high temperature stains, affecting the light bulb transmittance.
8, the room where the semi-automatic biochemical analyzer is placed should be kept dry and dust-free.
