The detector is designed for highest optical performance, GLP compliance and easy maintenance. 

Agilent G4212B 1260 DAD (Diode Array Detector)

It includes the following features: 

  • Maximum of  80 Hz G4212B data acquisition rate. 
  • Higher sensitivity for conventional LC as well as ultra fast applications by using next generation optical design. 
  • Increased sensitivity with 60 mm Max-Light cartridge flow cell. 
  • Optimized cell geometry for less peak dispersion for narrow bore applications. 
  • Max-Light cartridge flow cells for standard and bio-inert applications are available. 
  • More reliable and robust peak integration process (automated) due to less baseline noise/drift/refractive index and thermal effects especially under ultra fast gradient conditions. 
  • RFID tracking technology is used for the UV-lamp and the Max-Light cartridge flow cells. 
  • Multiple wavelength and full spectral detection at 80 Hz G4212B sampling rate, keeping up with the analysis speed of ultra-fast LC. 
  • Fixed 4 nm slit for rapid optimization of sensitivity, linearity and spectral resolution provides optimum incident light conditions. 
  • Improved Electronic temperature control (ETC) provides maximum baseline stability and practical sensitivity under fluctuating ambient temperature and humidity conditions. 
  • Additional diagnostic signals for temperature and lamp voltage monitoring. 
  • Easy exchange of flow cell by cartridge design.
