The invention discloses a deep ultraviolet spectrum measurement and spectrophotometry measurement device. The measurement device comprises a transmissive deep ultraviolet deep ultraviolet spectrum measurement and spectrophotometry measurement device and a reflective deep ultraviolet spectrum measurement and spectrophotometry measurement device. A liquid drop holder, an optical fiber sensor, a deep ultraviolet spectrum detection device and signal extraction and multiple-order derivative analysis software are sequentially arranged on the light path of incident light output by an excitation light source of deep ultraviolet; a liquid drop to be detected is arranged between two opposite and parallel solid end faces of the liquid drop holder and the optical fiber sensor. The deep ultraviolet spectrum measurement and spectrophotometry measurement device can be used for measuring a deep ultraviolet spectrum and absorbancy; trace samples of hard drugs and explosives have higher absorption peaks at the deep ultraviolet
