  The ALICE TPC provides excellent charged particle tracking for the study of
pp and Pb-Pb collisions at LHC. The TPC also allows particle identification via
the measurement of the specific ionisation dE/dx. At high pT (pT > 3 GeV/c)
this is accomplished in the region of the relativistic rise of the energy loss.
From the energy loss distributions the yields of charged pions, kaons, and
protons can be determined in bins of pT and pT-spectra are constructed. Here we
present the performance of such an analysis in pp collisions at 7 TeV for
charged pions up to 10 GeV/c.
