In the October 2023 installment of “Sample Prep Perspectives,” we reported results obtained from a survey on sample preparation techniques, and compared those to results from previous surveys. The results uncovered trends in the field over the last generation and their impact in areas such as which technologies are currently being used, sample types, and sample load. This installment will continue our look at the sample preparation survey, focusing on sample sizes, laboratory techniques used, automation, the use of solid-phase extraction (SPE) devices (cartridges, disks, plates, tips), SPE chemistries and selection criteria, and problems encountered in SPE.
