( Brand: Agilent ), ( Manufacturer Part Number: G42108A ), ( Part Type: Light Detector )
The Agilent G42108A Evaporative Light Scattering Detector (ELSD) is a high-performance analytical instrument designed for use with liquid chromatography (LC) systems. This ELSD model is specifically engineered to provide excellent detection capabilities for non-volatile and low-volatility compounds, such as polymers, proteins, and pharmaceuticals.
The G42108A ELSD features a unique nebulizer design that reduces the necessity for sample preparation, making it an ideal choice for sample matrices that are challenging to analyze using other detection methods. The nebulizer utilizes a low-pressure nitrogen gas stream to evaporate and nebulize the sample, resulting in a fine aerosol that is then passed through a light scattering cell. The light scattering cell contains a heated solution, which causes the aerosol to evaporate further, resulting in a cloud of particles that scatter light as they pass through the light beam. The intensity of the scattered light is directly proportional to the concentration of the analyte, allowing for quantitative analysis.
The Agilent G42108A ELSD is equipped with advanced software that allows for easy data acquisition and analysis. The software provides real-time data display, peak integration, and data manipulation capabilities. Additionally, the software offers multiple integration methods, including Gaussian, Lorentzian, and PeakFit, to ensure accurate and precise quantitative results.
The G42108A ELSD is built with high-quality components and is designed for long-term operation. The detector is rugged and can withstand harsh laboratory conditions, making it a reliable and dependable addition to any LC system. With its excellent detection capabilities, easy-to-use software, and rugged construction, the Agilent G42108A Evaporative Light Scattering Detector is an indispensable tool for any lab that requires quantitative analysis of non-volatile and low-volatility compounds.
