Say I have a spectrophotometer that has a grating monochromator. If I want to measure emission instead of absorption from a lamp, could I just remove the exit slit? By removing the exit slit, doesn't all of the light just hit the sample?

what kind of detector are you using? If you're using a lamp (continuum or for instance sodium lamp) and you're just measuring the atomic emission spectra than you could probably use a single channel detector to scan the wavelengths without removing the exit slit. If you're using a multichannel detector, for instance a charge couple detector, than you'll need to open up the exit slit.
