What is a chemistry analyser?
A chemistry analyzers measures the concentration of substances in blood or other body fluids. Using specific chemical reactions, those results are read with photometric methods. A chemistry analyser has a wide range of uses: from clinical diagnosis and monitoring of drug use to medical jurisprudence and many more.
Chemistry analyzers mainly include dry chemistry analyzers and liquid chemistry analyzers. The former uses sample impregnated strips, on which chemical reactions are detected. The latter is used to identify substances in a solution. There are many models, some of which can only measure one parameter, such as blood glucose meters and hemoglobinometer. Others can measure more than ten parameters.
Chemistry analyzers exist as bench-top devices with varying degrees of automation and portability devices. Some models, designed for tropical climates, have electronic components to protect them against moisture. Chemistry analyzers cover a whole family of instruments, including photometers and colorimeters. They are often called with the name of the analysis they are used to perform.
The primary purpose of chemistry analyzers
In the medical analysis laboratory, a chemistry analyser is used to measure one or more substances (analytes), such as glucose, urea, creatinine, hemoglobin, cholesterol, and whole blood, urine, serum, or plasma. It is also used to perform liver and kidney function tests.
Liquid Chemistry Analyser
The liquid chemistry analyser is a photometer. Unlike the spectrophotometer, it does not have a prism or a diffraction grating. A color filter (one of several filters or a single one) is used to measure the absorption of light in liquid samples according to Beer-Lambert’s law.
The analyser in liquid chemistry generally uses as a light source- a halogen lamp equipped with filters. The latest models use one or more LED lamps emitting light at specific wavelengths. Liquid sample tests are based on the production of a colored derivative of the analyte in the presence of specific agents. The color is directly proportional to the concentration of the substance(s) in the solution. The measurements are conventionally made between 304 and 670 nm or with additional filters. Some devices can perform kinetic measurements of concentration as a function of timer.
Dry Chemistry Analyser
The dry chemistry analyser is a reflectance photometer. The figure on the right shows the interaction of light and matter from different sources. The one that interests us is “reflection.” Moreover, the measurement used in Dry Chemistry Analyser machines is called “reflectance”.
The reflectance photometer provides a quantitative measure of the intensity of a chemical or biochemical reaction producing color on a surface (e.g. microscope slide, test strip, reagent stick, or patch). The light is emitted at a specific wavelength on the strip by the light source of the device (e.g. a light emitting diode or LED). The colored product absorbs this light wavelength. The higher the concentration of the analyte in the sample, the more intense the coloration and the less light is reflected. The detector of the device measures the reflectance of this enzymatic or chemical color reaction on the reagent stick or the test strip. Then it converts into an electronic signal. This signal is translated into the corresponding concentration of the analyte in the tested biological fluid, and the result is printed or displayed on a monitor.
A step forward for laboratories
Several devices are available on the market, including the liquid chemistry analyser and the dry chemistry analyser. However, because our main topic here is the latter, the following product is considered to be on top of the list when it comes to dry chemistry analyzers. It offers several functions and can diagnose certain conditions. This device can be seen as a step forward in the industry.
Set the standard of care
The DC-101 Dry Chemistry Analyser is a fully automated bench-top analyser with intelligent features for maximum efficiency. During its development, special attention was paid to the ease of handling it, its low service and maintenance costs. This lead to an ideal system of clinical chemistry for many laboratories and health-care professionals.
Using Wondfo’s original Dry Chemistry Analyser test strip, the DC-101 Dry Chemistry Analyser can help diagnose several items, including such liver function, kidney function, myocardial enzyme, emergency treatment, blood routine examination, and blood glucose.
Just one to five minutes are needed to get the results of the test, which is a merit in the industry where time is precious. The simplicity of the software interface significantly facilitates its test efficiency, which transforms the whole test operation in a quick and effective one. Operating steps are shown below:
- Preheating the device;
- Selecting the item on the touch screen;
- Inserting ID chip;
- Adding sample;
- Printing the results.
With those simple six steps for performing a full test, the DC-101 Dry Chemistry Analyser can be considered as a unique analyser in its category. With fast, accurate, and user-friendly interface, this small portable device is suitable for emergencies and clinical laboratories requiring high timeliness.
