TOYDAD 800 Scanning UV Detector

Information
TOYDAD 600 scan click to zoom Catalog No.: TOY33000


Four wavelengths simultaneously, 5 Hz scan of whole spectrum 200 - 800 nm in 3 nm steps

Description

TOYDAD 800 Scanning UV Detector is an OEM built-in UV detector suited for preparative and flash chromatography with diode array (DAD) in range 200 - 800 nm. This scanning version offers measuring at four wavelengths simultaneously with a possibility to see 5 Hz scan of whole spectrum in 3 nm steps.

More wavelengths or scan are used in liquid chromatography to verify purity of analyzed samples or in situations when some peaks absorb on different wavelengths.

Most important features of TOYDAD detectors:

  • small dimensions
  • built-in counter of lamp working hours
  • easy replacement of flow cell
  • measuring at more wavelengths simultaneously
  • sophisticated diagnostic software
