WebPhotometric detectors measure absorbance in the ultraviolet (UV) or visible regions of all the components in the column eluate. They are less universal than refractive index detectors but by the same token are more specific. This type of detector is normally capable of detecting nanomoles, provided that the compound contains a strong chromophore.
