Abstract
A detector for use in liquid chromatography is provided. The detector includes a light delivery system comprising a light source that emits one or more spectral lines of light of a light spectrum. The detector has an entrance slit configured to receive the one or more spectral lines of light and a wavelength selection module comprising a digital micro-mirror device. The digital micro-mirror device is configured to redirect the one or more spectral lines of light to a flow cell. The flow cell is optically connected to the wavelength selection module.
Claims19
A detector for liquid chromatography comprising:
- a light delivery system comprising a light source that emits light having a plurality of wavelengths;
- and
- a wavelength selection module optically coupled to the light delivery system, the wavelength selection module comprising:
- a spectrally dispersive optical element to receive the light from the light delivery system and to provide diffracted light having a linear dispersion of the wavelengths;
- and
- a digital micro-mirror device configured to receive the diffracted light and to selectively reflect one or more of the wavelengths into an output beam.
