The HSDC is comprised of a fused silica cell body and removable capillaries. The light path through the cell is made from black fused silica which significantly minimizes stray light and defines the aperture for the diode-array spectrometer.

• Up to 10-fold increase in signal-to-noise
• Detector linearity beyond 2000 mAU for accurate quantitative analysis
• Decoupled design allows replaceable capillaries and reduced cost operation
• Special capillary geometry ensures maintenance of peak symmetry
• Full diode-array spectral capabilities
• Design fits all Agilent CE instruments

The reflective interior functions as a 'lightpipe', ensuring almost 100% transmission of light. These properties result in enhanced linearity and unsurpassed spectral fidelity with the diode-array detector. The high linear range allows quantification of both less than 0.1% impurities and the main component in one run. Integral to the HSDC function is maintenance of peak shape. The unique geometry of the capillaries ensure proper coupling with the cell. The end of these capillaries include both a flaring of the inner diameter and beveling of the outer diameter.
