Thermo Fisher Scientific introduces the Prelude LX-4 MD HPLC, listed with the FDA as a Class I medical device for general clinical use. Clinical laboratories requiring high-throughput separations for their LC-MS assays now have access to a new four-channel, high-performance liquid chromatography (HPLC) system designed to increase the productivity and efficiency of clinical sample separations, while freeing valuable bench space. This system quadruples the productivity of a single-channel HPLC using four parallel channels that deliver up to four separations in a single instrument, streamlining LC-MS workflows, and reducing mass spectrometer idle time. The four channels can run identical or different LC-MS assays simultaneously, which provides flexibility for varying clinical separations and maximizes mass spectrometer utilization.
