1290 Infinity II Diode Array Detector FS

 Ultrasensitive and fast UV-spectral detection

The Agilent 1290 Infinity II Diode Array Detector FS (fixed slit) is based on the Agilent Max-Light cartridge cell with optofluidic waveguides that improve light transmission to near 100% efficiency without sacrificing resolution caused by cell dispersions effects. With typical detector noise levels of < ± 0.6 µAU/cm the revolutionary 60 mm flow cell gives up to 10 times higher sensitivity than detectors with conventional flow cells. Any compromising refractive index and thermal effects are almost completely eliminated, resulting in significantly less baseline drift for more reliable and precise peak integration. For fast separations, the 1290 Infinity II DAD FS offers multiple wavelength and full spectral detection at sampling rates up to 120 Hz

  • Universal Agilent Max-Light standard cartridge cell with 10 mm optical path length provides high sensitivity (noise: < ± 3 µAU) and low peak dispersion for 2.1, 3 and 4.6 mm id columns.

  • Multiple wavelength and full spectral detection at high sampling rate of 120 Hz, keeping pace with fast analysis speeds.

  • More reliable and robust peak integration process due through less baseline drift.

  • Full spectral detection for compound identification by spectral libraries or verification of the separation quality with peak purity analysis for ultrafast LC. Simultaneous detection of up to 8 signals for increased sensitivity and selectivity.

  • Upgrade option to 1290 Infinity II HDR DAD solution provides 30x wider linear range for samples with widely different concentration levels. More details

  • Radio frequency identification (RFID) technology for flow cells and lamp provide new levels of data security and traceability.

  • Next generation of electronic temperature control (ETC) provides maximum baseline stability and practical sensitivity under fluctuating ambient temperature and humidity conditions.
