1290 Infinity II Diode Array Detector
Ultrasensitive and ultrafast high resolution UV-spectral detection
The 1290 Infinity II Diode Array Detector (DAD) and the 1290 Infinity DAD FS are based on the Agilent Max-Light cartridge cell with optofluid waveguides, which improves light transmission to near 100% without sacrificing resolution caused by cell dispersions effects. The revolutionary 6 cm flow cell with typical detector noise levels of < ± 0.6 µAU/cm allows an up to 10 times higher sensitivity than detectors with conventional flow cells . Any compromising refractive index and thermal effects are close to completely eliminated, which results in significantly less baseline drift for more reliable and precise peak integration. The 1290 Infinity II DAD offers multiple wavelength and full spectral detection at sampling rates up to 240 Hz for ultrafast separations, while the 1290 Infinity II DAD FS provides sampling rates up to 120 Hz for fast LC.
Features
- High sensitivity through universal Agilent Max-Light cartridge cells with 10 mm optical path length (typically noise
< ± 0,3 µAU/cm) and lowest peak dispersion for 2.1, 3 and 4.6 mm ID columns. - Optional flow cell with 60 mm optical path length for a 10 times higher sensitivity.
- Programmable slit from 1 to 8 mm of the 1290 Infinity II DAD provides optimum incident light conditions for rapid optimization of sensitivity, linearity and spectral resolution. Fixed slit of 4 nm for the DAD FS.
- Multiple wavelength and full spectral detection at high sampling rate of 240 Hz, keeping pace with fastest possible analysis speed. Sampling rates of up to 120 Hz for the DAD FS offers fast LC.
- More reliable and robust peak integration due to less baseline drift.
- Full spectral detection for compound identification by spectral libraries or verification of the separation quality with peak purity analysis for ultra fast LC. Simultaneous detection of up to 8 signals for increased sensitivity and selectivity.
- Wide linear range (up to 2.5 AU) – for reliable, simultaneous quantification of primary compounds, by-products and impurities.
- Radio Frequency Identification (RFID) technology for flow cells and lamps provides a new level of data security and traceability.
- Electronic temperature control (ETC) provides maximum baseline stability and practical sensitivity under fluctuating ambient temperatures and humidity conditions.
- Optional upgrade to 1290 Infinity II High Dynamic Range (HDR) DAD, which provides 30x wider linear range for samples with widely different concentration levels.
