How we can correct the measured broadening line widths for the instrumental contribution if we use Voigt function in describing diffraction profile?

When describing diffraction profiles using a Lorentzian profile function correction of peak broadening is: B=B(measured)-B(instrumental) whereas using Gaussian profiles...
