We introduce a new technique for the measurement of the in-flight relative intensity calibration of high resolution spectrometers. This technique makes use of the free-free radiation in hot, dense active regions and flares, and combines it with spectral line intensities in an iterative procedure. After a few iterations, the relative intensity calibration and the temperature of the emitting plasma are determined. The application of this technique to the EIS instrument on board the Solar-B satellite (launch in 2006) is discussed.
