The present invention relates to apparatus, systems, and methods for
opening an autosampler sealed sample pan prior to TGA testing. The sealed
sample pan comprises a pan, cover, and bail. A notch is formed in the seal
sample pan cover. The cover can be opened by applying a concentrated force
to the inside of the notch with a punch element integrated into the
autosampler. This causes the center disk portion of the cover to be
partially sheared and the sealed sample pan to be opened. It also prevents
the punch element from touching the sample. A force sensor is used to
determine if the cover has been opened. If the cover has been opened, then
the sample pan is loaded to the TGA balance. If the cover has not been
opened, the autosampler will not load the pan and will automatically move
to the next sealed sample pan.
