UV Detector Types for Chromophors
Designed for highest sensitivity through innovative light mixing technology
Advanced optical detection with spectral sensitivity for method development
Devices called DAD or PDA detectors can record 3D UV-Vis data over the whole analysis time. With a DAD detector the entire UV-Vis spectrum of analytes passing through the flow cell. DAD are the preferred detector choice in research laboratories for HPLC method development.
3D data means that full UV-Vis spectra are measured and these spectra are plotted over the whole time. This is useful for unknown analytes or target compounds with different UV characteristics. The resulting UV-Vis spectra plots enable peak identification and monitor co-elution. Additionally 2D chromatograms can be extracted from 3D-data at any wavelength.
Both AZURA® diode array detectors DAD 6.1L and DAD 2.1L provide high spectral resolution enabling optimized identification and sample characterization with data rates up to 100 Hz.
Versatile Multi Wavelength UV-Detection with simultaneous acquisition compound-specific wavelengths
Devices called Multi-wavelength detectors (MWD), like the DAD, use a grating to disperse the light onto a photodiode array after the light has passed through the flow cell. Therefore, absorption occurs simultaneously across up to eight compound-specific wavelengths. Target analytes are molecules carrying a chromophore with adsorption at different wavelengths.
The AZURA MWD 2.1L is an 8 channel, very sensitive multiwavelength detector combining high performance with easy handling. Over a wavelength range from 190 to 700 nm, simultaneous detection of up to eight compound-specific wavelengths for optimum selectivity is provided at data rates up to 100 Hz. A wide range of easily exchangeable cartridge flow cells make this device the right choice for fast, standard analytical, semi-preparative and preparative separations with bio-inert or stainless steel wetted parts.
High sensitive UV-Detection for robust quantification of trace level components
Devices called UVD are variable wavelength detectors using a rotating grating to disperse polychromatic light into the spectrum. The light of a single wavelength is then selected and passed through the exit slit.
All lot of different KNAUER UV-Detectors with a wide range of easily exchangeable flow cells make this device the right choice for fast, standard analytical, semi-preparative and preparative separations with bio-inert or stainless steel wetted parts.
UV/VIS Flow Cells with no limitations
A wide range of easily exchangeable flow cells are the right choice for fast, standard analytical, semi-preparative and preparative separations with Bio-compatible or Stainless Steel wetted parts.
KNAUER flow cells in cartridge design are very easy exchangeable by just clicking them out without any tools.
