This document introduces the features and characteristics of the Agilent 1290/1260 Infinity Diode Array Detector, including its new optical design, new working principle, and new baseline interference minimization design, which makes its sensitivity more than ten times that of the Agilent 1200 Series UV Detectors.
This document is a technical note evaluating the sensitivity improvements of the Agilent 1290/1260 Infinity Diode Array Detector (DAD) compared to the Agilent 1200 Series UV Detectors. The comparison highlights the benefits of the new Agilent Max-Light cartridge cell technology, which utilizes optofluidic waveguides and total internal reflection to enhance light transmission.
| Detector noise (10 mm cell) | < + 3 pAU/cm |
|---|---|
| Detector noise (60 mm cell) | < + 0.6 pAU/cm |
| Dispersion volume (10 mm cell) | 1 pL |
