Used WATERS 2795 #9014057 for sale

WATERS 2795 is a high-performance liquid chromatograph mass spectrometer (LC/MS) that combines electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI). It is an instrument capable of simultaneously analyzing multiple chemical compounds at very high levels of both selectivity and sensitivity. It is a robust and power-efficient equipment that is capable of determining single chemical compounds in a sample with a detection limit in the subfemtomolar range. It is further capable of performing multiple elemental and isotopic analyses of the same sample simultaneously, allowing comprehensive chemical characterization of the sample. The ESI ionization source employed in 2795 utilizes a charged needle to ionize the sample directly at atmospheric pressure and then transfer the resulting ions to the mass spectrometer. While the APCI ion source is capable of responding to a wider array of sample types, including both positive and negative ions. The instrument further utilizes a triple quadrupole mass filter to achieve various analyses. This allows for scanning a sample for targeted substances, or to sequentially filter specified substances from the sample. The user can select from a variety of specific elements and isotopes, as well as perform scans with a large number of acquisition parameters. WATERS 2795 also utilizes a wide range of sample preparatory and analytical technologies. Modules including sample enrichment, chemical derivatization, electrolytic sample dilution, and extra-column sample focusing are available in order to maximize the analytical performance of the system. The unit can also be configured to perform solid phase extraction and LC/ MS-MS techniques. Overall, 2795 is a powerful and cost-effective tool for high-throughput bioanalysis and environmental research. It is capable of high- speed, high-throughput data acquisition, offers multi-tasking capabilities, and allows for the manipulation of numerous variables and parameters. This machine can be used in a wide range of analytical and research tasks, making it an ideal choice for those looking for high performance, reliability and versatility in an LC/MS tool.
