Technical Details 1260 Infinity Diode Array Detector 

Optofluidic waveguides technology
The new optical design of the 1260 Infinity DAD is based on the Agilent Max-Light cartridge cell with optofluidic waveguides. This new cell technology increases dramatically the light transmission by utilizing the principle of total internal reflection in a non-coated fused silica fiber, without sacrificing resolution caused by cell dispersions effects.

silica fiber. The cartridge design facilitate easy exchange of flow cells


Ultra UV sensitivity
The 1260 Infinity DAD with the revolutionary Max-Light cartridge cell with 60 mm path length is by far the most sensitive UV-detector in world - lets you discover what you have not seen before. With typical detector noise levels of less than ±0.6 AU/cm this revolutionary flow cell gives you up to 10 times higher sensitivity than the 1200 Series DAD or VWD.

Wide linear range
With a typical linear range of up to 2.5 AU the 1260 Infinity DAD allows the reliable, simultaneous quantification of primary compounds, by-products and impurities.

Highest baseline robustness
The optofluidic waveguides in the Max-Light cartridge cells eliminates almost any compromising refractive index and thermal effects, resulting in significantly less baseline drift for more reliable and precise peak integration

Highest baseline robustness through significantly reduced refractive index effects


Spectral confirmation and purity analysis
The spectral analysis of 54 spectra within the first peak confirms the purity at trace levels (<0.1 %) and under ultra-fast conditions. A library search identifies the peak as nifedipin with a match factor of 972. This positive spectral confirmation significantly enhances confidence in qualitative results
