1290 Infinity II Diode Array Detector
The 1290 Infinity II Diode Array Detector (DAD) delivers multiple wavelength detection with full spectra at sampling rates up to 240 Hz for ultrafast UHPLC separations. The detector's Max-Light flow cell features optofluidic waveguides, which improve light transmission to near 100% efficiency without sacrificing resolution caused by cell dispersions effects. With typical noise levels of ± 0.6 µAU/cm, the 60 mm path-length 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.
