The Agilent 1290 Infinity LC System - Product Description
System Components
The 1290 Infinity Diode-Array Detector
The 1290 Infinity Diode-Array Detector is a new optical design using a
cartridge cell with optofluidic waveguide technology offering high sensitivity
with low dispersion, a wide linear range and a very stable baseline for
standard or ultra-fast LC applications. The Agilent Max-Light cartridge cell
dramatically increases the light transmission by utilizing the principle of total
internal reflection along a non-coated fused silica capillary, achieving a new
level of sensitivity without sacrificing resolution through cell volume
dispersion effects. This design minimizes baseline perturbations caused by
refractive index or thermal effects and results in more reliable integration of
peak areas.
