Purifying the masses: Integrating prepurification quality control, high-throughput LC/MS purification, and compound plating to feed high-throughput screening

摘要

In this paper we report using a parallel, four-channel HPLC/MUX/MS purification system, the Purification Factory, to purify thousands of compounds destined for high-throughput screening in a single month. The maximum sample throughput during this 20-workday month was 704 samples/day. Since this purification throughput exceeded the postpurification sample and data handling capabilities provided by commercial solutions, a custom-integrated solution was designed to address these shortcomings. In this paper we detail the key improvements in automation, solvent handling, and sample handling logistics implemented to sustain a mean throughput of 528 samples/day over a multimonth time period.
