Water content and the trace quantity of volatile
components in PET fiber were quantified
Since this sample is a fiber-like, it is difficult to sample in
the usual crucible cell (φ6×5mm). It can sample easily by
using the large capacity cell of TGA-51 exclusive use,
and TG macro crucible (φ11×14mm) (referring to the
following figure) this time, and a very small quantity of
water of 0.167% and very small quantities of volatile
components were measured.
