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.
