We report some comparative results of an investigation devoted to study the spectral evolution of a sample of Gamma-Ray Bursts. They were simultaneously detected with both the Gamma-Ray Burst Monitor and the Wide Field Cameras aboard the BeppoSAX satellite and were reobserved with the Narrow Field Instruments aboard the same satellite.
