PN3241 UV Detector

PN3241 UV/DAD Detector

The PN3241 DAD detector provides users with a very high level of sensitivity and stability found in DAD detectors today. The PN3241 attains sensitivity levels approaching the most advanced UV-Vis detectors. With an 8 nm slit width it has a high-sensitivity mode. Using light-source compensation, it offers a noise level of 0.6×10-5 AU which is comparable to that of traditional UV-VIS detectors.

  • 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 - 2.0AU
    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.
  • Web Browser Control
    The PN3241 is equipped with an Ethernet interface and Web-control functions, allowing devices to be monitored and controlled from PCs in the network.
  • Additional Features
    The PN3241 can be used as a 4 channel UV-VIS detector which is esp. for customers that want to have more than one UV trace. An additional software can be ordered for using the PN3241 as a DAD detector to get spectral information and purity analysis.
