The paper concerns in the principle and the experimental results of gas-filled time-of-flight (GF-TOF) detector. 36Cl and 36S particles were successfully separated in the TOF spectra from the GF-TOF detector for the ion with the energy of 64, 48 and 33 MeV respectively. The comparison of the separation power of isobars between the GF-TOF method and the δE-E method was carried out. The experimental results indicate that the separation power of the δE-E method is better than that of the GF-TOF method at the energy larger than 40 MeV, and the GF-TOF method is better than the δE-E method at the energy less than 40 MeV, especially at the energy range of 20-40 MeV.
