World’s most sensitive and fastest diode-array detector
The Agilent 1290 Infinity Diode Array Detector (DAD) is the world`s most sensitive diode-array detector and features a completely new optical design based on the Agilent Max-Light cartridge cell with optofluidic waveguides. With typical detector noise levels of < ± 0.6 µAU/cm the revolutionary 6 cm flow cell gives up to 10 times higher sensitivity than the 1200 Series DAD and VWD. 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 ultra high productivity the 1290 Infinity DAD offers multiple wavelength and full spectral detection at sampling rates up to 160 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.
- Programmable slit from 1 to 8 nm provides optimum incident light conditions for rapid optimization of sensitivity, linearity and spectral resolution.
- Multiple wavelength and full spectral detection at high sampling rate of 240 Hz, keeping pace with fastest possible analysis speed.
- 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.
- Wide linear range (typically up to 2.5 AU) - for reliable, simultaneous quantification of primary compounds, by-products and impurities.
- 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
