1260 Infinity Diode Array Detector
The Agilent 1260 Infinity Diode Array Detector (DAD) 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 Agilent 1200 Series DAD and VWD detectors. Any compromising refractive index and thermal effects are almost completely eliminated, resulting in significantly less baseline drift for more reliable and precise peak integration. Multiple wavelength and full spectral detection with up to 80 Hz data rates allows precise identification, quantification and purity analysis at trace levels for ultra-fast LC separations.
-
Ultra sensitivity through revolutionary Agilent Max-Light cartridge cell with 60 mm optical path length (typically noise: <± 0.6 µAU)
-
Universal Agilent Max-Light cartridge standard cell with 10 mm optical path length provides high sensitivity (noise: <± 3 µAU)
-
Wide linear range (typically up to 2.5 AU) - for reliable, simultaneous quantification of primary compounds, by-products and impurities.
-
Upgrade option to 1200 Infinity HDR-DAD solution provides 30x wider linear range for samples with widely different concentration levels.
-
More reliable and robust peak integration process due through less baseline drift.
-
Full spectral detection up to 80 Hz for compound identification by spectral libraries or verification of the separation quality with peak purity analysis for conventional and ultrafast LC. Simultaneous detection of up to 8 signals for increased sensitivity and selectivity.
-
Radio frequency identification (RFID) tags for all flow cells and UV lamp provide new levels of data traceability by recording parameters such as cell dimensions, lamp usage, serial number etc.
-
Electronic temperature control (ETC) provides maximum baseline stability and practical sensitivity under fluctuating ambient temperature and humidity conditions.
-
Reference wavelength for elimination of background interference.
-
Early maintenance feedback (EMF) for continuous tracking of instrument usage in terms of lamp burn time with user-settable limits and feedback messages.
-
Extensive diagnostics, error detection and display with Instant Pilot controller and Agilent Lab Advisor software.
