Introduction of Vitrous Dry Chemistry Analyzer
Table of Contents
The Vitros Dry Chemistry Analyzer is a diagnostic instrument used in clinical laboratories for performing a variety of biochemical tests. It is manufactured by Ortho Clinical Diagnostics, a company specializing in clinical laboratory equipment and reagents.
The Vitros Analyzer utilizes dry-slide technology, which means that the reagents required for testing are incorporated into individual dry elements or slides. This eliminates the need for liquid reagents and simplifies the testing process. The analyzer automatically dispenses the appropriate reagents onto the slides, and the reaction between the sample and the reagents is then measured to determine the concentration of specific analytes.
Some of the key features of the Vitros Dry Chemistry Analyzer include:
- Dry-slide technology: The dry elements or slides contain all the necessary reagents, reducing the risk of contamination and improving testing efficiency.
- Random-access testing: The analyzer allows for simultaneous testing of multiple samples without the need for batch processing. This enables faster turnaround times for test results.
- Broad test menu: The Vitros Analyzer offers a wide range of tests, including those for clinical chemistry, immunoassay, and specific disease markers.
- User-friendly interface: The analyzer is designed with an intuitive user interface, making it easier for laboratory technicians to operate and navigate through various functions.
- Quality control and calibration: The analyzer incorporates quality control measures to ensure accurate and reliable test results. It also performs regular calibration procedures to maintain optimal performance.
The Vitros Dry Chemistry Analyzer operates based on the principle of dry-slide technology. This technology eliminates the need for liquid reagents traditionally used in clinical laboratory testing.
The dry-slide technology incorporates all the necessary reagents for a specific test onto individual dry elements or slides. Each slide contains reagents specific to a particular analyte or test parameter. These reagents are stable and can be stored for extended periods without refrigeration.
When a sample is loaded onto the analyzer, it automatically dispenses a small amount of the sample onto the appropriate dry slide. The sample rehydrates the reagents present on the slide, initiating a chemical reaction specific to the analyte being measured.
The reaction between the sample and the reagents generates a signal, such as color change or light emission, which is proportional to the concentration of the analyte in the sample. The analyzer then detects and measures this signal using appropriate detection methods.
The measurement of the signal is typically done using photometric or fluorometric techniques. For example, in photometric measurements, the analyzer measures the absorbance or transmission of light through the reaction mixture on the slide. The intensity of the signal is correlated with the concentration of the analyte, allowing the analyzer to provide quantitative results.
The Vitros Dry Chemistry Analyzer employs random-access testing, which means that it can process multiple samples simultaneously without the need for batch processing. This feature enables faster turnaround times for test results and greater flexibility in managing different test requests.
