Postnova - Model PN3211 -UV Detector

• 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 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 with various noise-reduction technologies to provide users with a wide dynamic range and allow for 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.
