Postnova model 3211 2-channel UV detector

An exceptional level of sensitivity and stability

As a high sensitive UV detector, model 3211 has a noise level of 0.5 × 10E-5 AU max., making it one of the most sensitive UV detectors (ASTM Standards). Model 3211 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 increase the baseline stability and the analysis reliability.
   
• Superior linearity ≥ 2 AU
  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
  Monitors two components in the UV range simultaneously.
