Throughput and Sample Capacity

Throughput refers to the number of tests the analyzer can perform per hour. The throughput of the BK200 can vary depending on the specific model and the tests being performed. However, it's generally designed to handle a significant number of samples, making it suitable for busy labs. The sample capacity refers to the number of samples the analyzer can process at one time. This includes both the number of sample positions on the rack and the ability to load emergency samples. The BK200 usually has a reasonable sample capacity, allowing the lab to handle a large number of samples without constant operator intervention. Knowing the throughput and sample capacity helps determine if the analyzer meets the lab's testing needs and ensures a smooth workflow.

Optical System and Measurement Capabilities

The optical system is a critical component of the BK200, responsible for measuring the absorbance of light through the reaction mixtures. The light source is typically a halogen lamp that produces a broad spectrum of light. The wavelength range of the analyzer determines the range of tests that can be performed. The BK200 often offers multiple wavelengths to analyze a wide array of analytes. The photometric accuracy refers to the precision with which the analyzer measures the absorbance of light. This is a critical factor in ensuring the accuracy of test results. The detector is usually a photodiode that converts light into an electrical signal, which the analyzer then processes. The cuvette type determines the type of reaction vessel used, which affects the reaction volume and the accuracy of the measurements. Understanding the optical system specifications is important for troubleshooting any issues with the analyzer and ensuring the reliability of test results.

Reagent and Sample Handling

The reagent and sample handling systems are designed to automate the process, reducing manual labor and the risk of contamination. The reagent system includes the number of reagent positions, reagent volume, and the ability to automatically mix the reagents. The sample handling system includes the type of sample containers that can be used and the volume of sample required for each test. The sample probe aspirates the sample from the sample container and dispenses it into the reaction cuvette. The reagent probe dispenses the reagents into the reaction cuvette. Automated reagent and sample handling helps to improve efficiency, reduce errors, and ensure the accuracy of the test results.

Calibration and Quality Control

Calibration and quality control are essential for ensuring the accuracy and reliability of the BK200. Calibration is the process of establishing the relationship between the analyzer's readings and the actual concentration of the analyte in the sample. This is usually done by using calibrators. Quality control involves running control samples to verify that the analyzer is performing correctly. This helps detect any errors and ensures the test results are reliable. The analyzer usually has calibration and quality control features that guide users through these processes and alert them to any issues.
