Interesting CNN article (link below). It says that "not since Apollo 17...",

... but, at the 'actual' Apollo 17 page, it says that the solar wind collector experiment was omitted

[Other experiments flown on prior missions were missing: the solar wind collector, the corner-cube laser reflector, and the passive seismometer. The science advisory committees felt that sufficient data had been collected that these experiments could be dropped in favor of new ones. The new experiments included a second type of cosmic ray detector, an instrument for determining the composition of the extremely thin lunar atmosphere, a device for detecting meteorites and ejecta from local impacts, and a long-period gravimeter intended as a gravity-wave detector.]

From Apollo 11:

THE SOLAR WIND COMPOSITION EXPERIMENT (SWCE)
A third experiment, a Solar Wind Composition Experiment (SWCE), was provided by scientists from Switzerland. It was deployed and returned to Earth by the crew for analysis. The aluminum foil panel, similar to household foil, collected atomic particles released by the Sun into space. After the mission, scientists in Switzerland analyzed the exposed foil, an indication of the world-wide participation in the Apollo program.

Being picky and searching for the truth can be fun and rewarding. Thanks, Jake. :)
