Purchase of LC-MS/MS mass spectrometer and UHPLC

The system must: -perform high-throughput targeted quantitative lipidomics, via dynamic MRM/SRM based on retention time, with analyte-specific time window, option to weight the dwell time for specific analytes, quantification of hundreds of mass transitions simultaneously, in both negative and positive mode in a single analytical run. -Ion source must accept either an electrospray ionization (ESI) probe or atmospheric pressure chemical ionization (APCI) probe, including a heated ESI probe for use in the ion source @flow rates from 100 to 500 µl/min without splitting at broad flow range from 1 μL/min to up to 3 mL/min with interchangeable probes and electrodes. -have a linear accelerator trap and triple quadrupole functionality; prove to be highly efficient at collecting and retaining ions from the ESI spray plume, while removing the gas molecules and neutral ions, ensuring a superior enhanced ion generation/ultra-high sensitivity. -Central control for the LC AD system/AC column oven
