PN3211 UV Detector

The PN3211 UV Detector provides an exceptional level of sensitivity and stability. As a high sensitive UV detector the PN3211 has a noise level of 0.5×10-5 AU max., making it one of the most sensitive UV detectors (ASTM Standards).

Features:
  • Greater Baseline Stability
    Supplied as standard, a temperature-controlled flow cell eliminates inconsistencies caused by changes in absorbance due to shifts in room temperature. This helps to increase the baseline stability and the analysis reliability.
  • Superior Linearity - 2.5AU
    Using newly developed signal processing technology the stray-light correction function has been enhanced and the linearity has been improved. This expanded linearity combines various noise-reduction technologies to provide users with a wide dynamic range and allows the analysis of your target compound and minor impurities in a single run.
  • Internal Validation Protocol
    The incorporation of a low-pressure mercury lamp for wavelength calibration ensures simple calibration in the ultraviolet region.
  • Dual-Wavelength Measurement
    Monitor two components in the UV range simultaneously.
