Model 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 to one of most sensitive UV detectors (ASTM Standards).
- 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.
