Biochemistry Analyzer Working Principle

Biochemistry analyzers are designed to be used in laboratories and hospitals for the purpose of analyzing various types of samples, such as blood, urine, saliva, and cerebrospinal fluid. They can perform a variety of tests, such as detecting lipids, sugar levels, and enzymes, in addition to determining the structure and function of biomolecules. The device is used in a number of industries, including pharmaceuticals and genetics.

Biochemistry analyzers are divided into three categories. These include semi-auto, automatic, and fully-automatic. Each type of instrument has its own unique features. Some analyzers have menu-driven programming, making them user-friendly.

Semi-automatic analyzers are geared toward medical practices and smaller labs. This is because they are typically designed to operate at lower speeds and handle less samples. However, they do require that each test be set up manually. In a fully-automatic analyzer, the tests can be set up in a chain, allowing the instrument to manage the process.

Fully-automatic analyzers are much faster than semi-automatic instruments and have a lower risk of human error. They are also more precise. As such, they can be used for high-throughput applications.

Automatic biochemistry analyzers are a great help for the medical industry. They can detect and measure a wide range of elements, such as enzymes, chemicals, lipids, and sugar. Furthermore, these analyzers can perform a number of tests, such as determining the functions of enzymes and antigen-antibody interactions in biochemical reactions.

Semi-automatic biochemistry analyzers are generally LCD or touch screen devices, which allow the operator to control the device. They also feature an external mouse, keyboard, and printer. Although they have lower speed, they are more flexible than the fully-automatic versions.

To run a sample, a specimen container is filled with reagents. It is then loaded into the device and moved in a preselected number of steps. Usually, the containers are numbered, to aid in the identification of the sample. When the sample is ready, the sampling probe is inserted into the sample container and moved to the cuvette. A convex lens then focuses the light, conversing with scattered light. At this point, the light passes through the sample and a photodetector determines its optical density. The resulting electrical signal is then fed to the microprocessor.

A bar code tube system is another important feature of the device. This is a convenient way for the device to efficiently manage tests. Using a bar code label, the device can identify the demographics of the patient and the test request.

There are also ion-selective electrodes, which are a great advancement in the technology. The ion-selective electrodes help improve the rate of the test. Ion-selective electrodes are most commonly found in blood gas analyzers, as they provide a better precision for measuring ions.

Specimen containers have a barcode label attached to them. This allows the device to identify the sample, manage the test, and keep track of its status. Typically, these containers are disposable, but some are reusable. With this option, the user can continue to operate the analyzer without needing to replace the cuvette.
