He worked alongside engineers and scientists from DuPont, Westinghouse Electric Company, Honeywell, and members of Institute of Electrical and Electronics Engineers committees, contributing to instrument design and process control. His notable projects involved collaborations with teams at Argonne National Laboratory and joint ventures incorporating technology from IBM and AT&T research. Sweet developed prototype apparatus used in experimental programs funded by the Department of Energy and cooperative research with the American Chemical Society.

Major works attributed to Sweet encompassed design and refinement of analytical instruments, control systems for materials processing, and compact, modular laboratory devices. He consulted for manufacturers such as PerkinElmer, Thermo Fisher Scientific, and Beckman Coulter, and participated in standards discussions at organizations like the American Society for Testing and Materials and the International Electrotechnical Commission. His practical designs were employed in projects with Shell Oil Company and ExxonMobil downstream laboratories, and integrated into pilot plants influenced by work at Oak Ridge National Laboratory.

Scientific contributions and impact

Sweet's scientific contributions centered on instrument miniaturization, signal conditioning, and reproducible sample handling. He advanced techniques that improved accuracy and repeatability in spectroscopy and chromatography, affecting workflows in analytical chemistry labs run by teams from Pfizer, Merck & Co., and Eli Lilly and Company. His innovations influenced measurement protocols referenced by committees within the Royal Society and standards adopted in industrial test methods promoted by the American Institute of Physics.

His impact extended to cross-disciplinary collaborations linking applied physics, materials science, and industrial chemistry. Sweet's devices enabled researchers at institutions such as Harvard University, Yale University, University of California, Berkeley, and California Institute of Technology to pursue experiments with greater throughput and lower sample volumes. The improvements he introduced were incorporated into curricula at technical schools and discussed at conferences hosted by the American Physical Society and the Materials Research Society.

Publications and patents

Sweet authored and coauthored numerous technical reports, conference papers, and articles in peer‑reviewed outlets. His publications appeared in journals and proceedings affiliated with organizations like the Institute of Electrical and Electronics Engineers, the American Chemical Society, and the Royal Society of Chemistry. He contributed chapters to edited volumes alongside researchers from Columbia University, Princeton University, and Johns Hopkins University.

He held patents concerning instrument components, fluid handling modules, and signal processing circuits. Patent assignees and collaborators included industrial entities such as Honeywell International, Siemens, and smaller specialist firms connected to the Silicon Valley innovation ecosystem. Sweet's patented technologies were cited by later patents filed by researchers at MIT Lincoln Laboratory, Bellcore, and corporate laboratories of Microsoft and Intel for sensors and automation methods.
