The 75th Pittcon was held at the San Diego Convention Center, California, on February 24–28, 2024, for the first time on the West Coast. San Diego, a city of 1.3 million, is renowned for its moderate year-round temperatures and outstanding tourist attractions (including Gaslamp Quarter, Balboa Park, the San Diego Zoo, Sea World, La Jolla, Coronado, and Legoland), and academic and industry centers (UC San Diego, Scripps Institute, Salk Institute, Qualcomm, and Illumina). Its proximity to Los Angeles and the availability of many moderately priced hotels make it an ideal conference venue. The Pittcon organizer recently changed the meeting locations from a four-city rotation of Philadelphia, Chicago, Atlanta, and New Orleans to a new city list of San Diego, Boston, and San Antonio. We hope exhibitors and attendees will embrace these exciting locations.

I have attended Pittcons for four decades, and Pittcon 2024 remained a rewarding and inspiring experience. Unfortunately, the number of exhibitors was significantly reduced post-pandemic, and several major manufacturers (Agilent, Thermo Fisher Scientific, Sciex, and Waters) were absent from the exhibition hall this year. I want to appeal to all instrument manufacturers to reconsider returning to the most prominent American laboratory conference to benefit laboratory scientists and consumers seeking to purchase new equipment, software, and consumables. I hope the Pittcon organizing committee will continue to deliver a conference of increasing relevance to the analytical science community and instrument manufacturers. I fervently hope to see more manufacturers at the exhibition halls of Pittcon 2025 in the city of Boston, the new pharmaceutical hub in America.
