Throughout 2022–2023, instrument manufacturers released new HPLC and mass spectrometry (MS) products into the market. Pittcon 2023 gave these companies an opportunity to showcase them in-person in front of thousands of conference attendees. Although not all manufacturers attended Pittcon this year (in fact, several big manufacturers opted out of attending), that does not mean their products are any less worthy of discussion.
Table I lists new product introductions ordered alphabetically by the vendor’s name from 2022 to 2023, categorized as HPLC systems, modules, MS, CDS, and other software. The HPLC system category includes ion chromatography (IC), LC–MS, and capillary electrophoresis (CE) instruments. Each product’s features and benefits are briefly described, including a summary of specifications (including, but not limited to, pressure and flow rate ranges, mass range, resolution, and scan rates). The footnotes of Table I define the common acronyms used in the text.
This section describes new HPLC, UHPLC, IC, CE, and LC–MS systems and their salient features, benefits, and technical specifications.

I have attended Pittcons for four decades, and Pittcon 2023 remained a rewarding and inspiring experience (7). I want to appeal to all instrument manufacturers to reconsider a return to the most prominent American laboratory conference for the benefit of laboratory scientists and consumers. I am hopeful that the Pittcon organizing committee, which did a stellar job in the past 70+ years, will continue to deliver a global conference of increased relevance to the analytical science community and instrument manufacturers alike.
