Used WATERS Alliance 2690 / 432 / 996 #293685943 for sale

WATERS Alliance 2690 / 432 / 996 is a powerful and versatile high-performance liquid chromatography (HPLC) equipment that is widely used in research, pharmaceutical, and environmental analysis laboratories. This spectrometer is a combination of three key components - the 2690 separations module, the 432 detector, and the 996 photodiode array detector, which work together to provide accurate and precise analytical results. The 2690 separations module is the heart of the system, responsible for the separation of sample components in a liquid chromatography analysis. It features a binary high-pressure mixing pump that delivers precise flow rates and gradients for optimal separation performance. The pump is capable of operating at high pressures, up to 6000 psi, allowing for the analysis of a wide range of compounds with varying polarities and molecular weights. The 2690 module also includes an autosampler that can automatically inject samples into the chromatographic unit, improving workflow efficiency and reducing the risk of human error. The autosampler has a high sample capacity, allowing for the analysis of multiple samples in a single run. It also has the ability to perform online dilutions, making it suitable for analyzing samples with different concentrations. The 432 detector is a single-wavelength UV/Visible detector that is used for quantifying analytes in the liquid chromatography machine. It operates at multiple wavelengths to provide flexibility in method development and analyte detection. The detector has a wide linear dynamic range, ensuring accurate quantification of compounds over a wide concentration range. It also features a low noise level, enhancing the detection sensitivity of the tool. The 996 photodiode array (PDA) detector is a more advanced detector that offers additional capabilities compared to the 432 detector. The PDA detector operates at multiple wavelengths simultaneously, allowing for real-time monitoring of analyte spectra and peak purity. This enables the identification and quantification of complex mixtures with multiple components. The PDA detector has high resolution and sensitivity, making it suitable for the analysis of trace-level impurities and degradation products. Alliance 2690 / 432 / 996 spectrometer is controlled by dedicated software that allows for easy asset operation, method development, and data analysis. The software provides tools for model control, gradient programming, data acquisition, and peak integration. It also offers advanced data processing features, such as peak deconvolution, spectral matching, and quantification calculations. In conclusion, WATERS Alliance 2690 / 432 / 996 is a reliable and efficient HPLC equipment that offers high performance and versatility for a wide range of analytical applications. Its combination of the 2690 separations module, 432 detector, and 996 PDA detector provides accurate and precise results, making it an essential tool for analytical laboratories.
