A cytometer, or flow cytometer, is a specialized instrument used to study cells or particles in a liquid sample. It passes the sample through a tiny channel, shining a laser on it. The cells or particles scatter light and emit fluorescence, which is measured by detectors. This information helps identify the cells and understand their properties, like size, complexity, and surface markers. Cytometers can analyze multiple characteristics simultaneously and are used in various fields like research, diagnostics, and drug discovery.
Electronic pressure regulators, including I/P or E/P transducers, are essential components for cytometers to provide precise fluid pressure control within the fluidic system. These are sometimes called pressure over liquid applications, where pressure is applied to a vessel of some liquid or reagent. They maintain consistent and accurate fluid flow rates during cell analysis.
Electronic pressure regulators are typically employed in the sample injection and sheath fluid systems in cytometry. These systems ensure a controlled and steady flow of cells and sheath fluid to enable accurate cell analysis. Electronic pressure regulators help control the pressure applied to the sample injection system in the sample injection system. They maintain a constant and controlled pressure as the sample is introduced into the cytometer. This ensures that the cells are injected at a consistent rate, allowing for accurate analysis, and preventing variations in sample delivery. In the sheath fluid system, cytometers use a sheath fluid to focus the cells and create a single-file stream for analysis. Electronic pressure regulators are crucial in maintaining stable pressure in the sheath fluid system. By regulating the pressure, they ensure a steady flow of sheath fluid, which is critical for proper cell alignment and positioning within the cytometer. This allows for accurate cell detection and analysis.
Overall, electronic pressure regulators contribute to the stability and accuracy of fluid flow in cytometers. By precisely controlling the pressure in the sample injection and sheath fluid systems, they ensure consistent and reliable cell analysis, improving the quality and reliability of cytometric measurements.
