Used WATERS 2695 #9165849 for sale

WATERS 2695 is a high performance liquid chromatography (HPLC) equipment used for the separation, identification, and quantification of small molecules and biomolecules. This system includes an advanced UV-VIS Absorbance Detector to allow for quantitative analysis of compounds. It is used widely in the study of pharmaceuticals, carbohydrates, proteins, and peptides. The unit's components consist of an HPLC Pump, an autosampler, and the UV-Vis detector. The HPLC pump is the heart of the instrument. Compressed air or a pressure source is used to push the mobile phase which is then pumped through the column of the HPLC. This results in the separation of the different molecular species due to differences in their affinity for the stationary phase. On the other hand, the autosampler reduces the time and effort involved in manual sample loading. It supports injection volumes of up to 300 ul and can be programmed to rapidly sample multiple vials. The UV-VIS absorbance detector measures the amount of light absorbed when a sample travels through a beam of light. This signal is then sampled by the microprocessor and displayed graphically as a peak using the chromatogram. The detector has an adjustable wavelength range of 190- 800 nm with an adjustable bandwidth of 1, 2, 5, 10 and 20 nm providing for very precise measurements. The data output from 2695 is available in multiple formats including LabView, Flexible Data Format (FDF), and ASCII (American Standard Code for Information Interchange) files. The data can then be analyzed and stored for future use. The machine also has flexibility with regard to column types, including isocratic, gradient, and 2D as well as its ability to use a variety of mobile phases. Overall, WATERS 2695 is a powerful, flexible, and reliable tool used for the separation and quantification of small molecules and biomolecules in a variety of applications. Its range of adjustable parameters, high detailed resolution, and data output capabilities, make it an invaluable and versatile tool in chemical analysis.
