D3230 & 3240 Diode Array Detector

The D3230 and D3240 Diode Array Detectors feature an advanced optical system incorporating an ellipsoidal mirror, toroidal mirror, and an imported flat-field imaging grating, delivering high light throughput, low stray light, and excellent wavelength accuracy. They utilize high-sensitivity CMOS linear image sensors with 512 or 1024 pixels, achieving spectral resolutions of 1.2 nm and 0.6 nm, respectively. The detectors support multiple operating modes including multi-wavelength monitoring, 3D spectral acquisition, peak purity analysis, and spectral library searching. Intelligent features include automatic power-on self-test, deuterium lamp usage tracking, and seamless integration with Chromsoft/Kromstation workstations via UDP communication. Optimized airflow and cooling design ensure low baseline drift and extended lamp life, while tool-free deuterium lamp replacement requires no optical realignment.

Performance

The D3230 and D3240 Diode Array Detectors are designed for high-performance liquid chromatography (HPLC) systems, enabling simultaneous acquisition of full UV-Vis spectra (190–800 nm) and multiple chromatographic signals in real time. They generate 3D spectro-chromatographic data, allowing post-run extraction of chromatograms at any wavelength, determination of peak purity, and identification of compounds via spectral library matching. With flexible sampling rates, adjustable exposure time, and reference wavelength correction, these detectors deliver low noise, high linearity, and excellent baseline stability. Fully integrated with Chromsoft or Kromstation workstations via UDP, they support automated method control, data processing, and customizable reporting, making them ideal for pharmaceutical, environmental, and research laboratories requiring comprehensive spectral information.
