When choosing a biochemistry analyzer, you can have a lot of doubts when facing the testing speed and optical parameters of biochemistry analyzers. This article will provide you with a detailed introduction to the testing speed and optical parameters of biochemistry analyzers.

1. Testing speed of biochemistry analyzer


Test speed is one of the important parameters for choosing a biochemistry analyzer. It reflects the ability of the biochemistry analyzer to process samples per unit of time. It is generally expressed in terms of the number of tests completed per hour.

It should be noted that when the biochemical analyzer is equipped with electrode part, its test speed can be calculated independently. In particular, when comparing multiple biochemical analyzers, the biochemical and electrode sections should be compared separately.

There is no uniform calculation method for the test speed of biochemistry analyzer, and the speed indicated by the manufacturer is for reference only. In practice, the factors affecting the speed of testing also include the time required to automatically clean the instrument pipeline. Or the first test result completion time. The general small biochemical analyzer requires a shorter cleaning time.

2. the optical parameters of biochemical analyzer

In addition to the characteristics of spectroscopic technology, biochemical analyzers in a certain wavelength range of monochromatic light wavelength (or filter) number should be able to meet the needs of laboratory testing work. Wavelengths are usually in the range of 300 to 800 nm. The number of fixed wavelengths of the biochemistry analyzer should be more than 11.

Biochemistry analyzer detector absorbance value range of 2.0 or more, has been able to meet the requirements of the actual clinical work. And the colorimetric cell optical diameter can directly affect the effective range of absorbance values and resolution. When the optical diameter is longer, it is easy to get better sensitivity and precision. However, the volume of reagents and samples (minimum reaction volume) will increase.

The testing speed and optical parameters of biochemistry analyzer are important reference indicators when purchasing biochemistry analyzer. Please do not ignore it.

On the contrary, the most important feature of POCT machine is "small, fast and non-professional operation". Theoretically, all kinds of blood markers can be detected. However, the most common ones are blood glucose, blood gas, blood coagulation, infectious diseases (viral and bacterial), liver function, kidney function, pregnancy test, urine test, cardiac markers, tumor markers, etc.

8 tips for using semi-automatic biochemistry analyzer

2021-10-18

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.
