DAD3100 Diode Array Detector (DAD)

The DAD3100 Diode Array Detector features an advanced optical system with an aberration-corrected grating and a unique wavelength calibration method, delivering high light throughput, low stray light, and excellent wavelength accuracy. Equipped with a 512-element CMOS linear image sensor, it achieves a spectral resolution of 1.2 nm. The detector supports simultaneous acquisition of both chromatograms and full UV-Vis spectra (190–800 nm), enabling 3D spectro-chromatographic data generation for peak purity analysis and spectral library searching. It offers flexible multi-channel signal output, adjustable sampling rate (1–40 Hz), and selectable time constants (0 s, 1 s, 2 s). Intelligent features include automatic power-on self-test, real-time lamp status monitoring, and seamless integration with Chromsoft/Kromstation workstations via UDP communication. Tool-free deuterium and tungsten lamp replacement requires no optical realignment, and the closed optical system design ensures long-term stability and low baseline drift.

Performance

The DAD3100 Diode Array Detector is designed for high-performance liquid chromatography (HPLC) systems, enabling real-time acquisition of full UV-Vis spectra (190–800 nm) and multiple chromatographic signals simultaneously. It generates 3D spectro-chromatographic data, allowing post-run extraction of chromatograms at any wavelength, automated peak purity assessment, and compound identification through spectral library matching. With flexible sampling rates, selectable time constants, and UDP-based communication, the detector supports fully automated method control and data processing via Chromsoft or Kromstation workstations. Its high sensitivity, low noise, and excellent linearity make it ideal for pharmaceutical, biomedical, environmental, and research applications requiring comprehensive spectral analysis and high-confidence quantification.
