Optimizing the Detector
Optimization Overview
Choosing a Flow Cell
Several flavors of the Max-Light Cartridge Flow Cell are available, see
High Sensitivity
If higher sensitivity is necessary, the Max-Light Cartridge Cell ( 60 mm, V(σ)
4.0 µL) (G4212-60007) can be used. This cell enhances the detector by lowering
the limit of detection (LOD) by a factor of about 3 (depending on the application).
Normal Applications
The Max-Light Cartridge Cell ( 10 mm, V(σ) 1.0 µL) (G4212-60008) covers a wide
range of applications:
•
all column diameter down to at least 2.1 mm ID or even less
•
applications with peak dispersion (Peakwidth x flow) down to
~
2 µL [example:
pw = 0.04 min at flow = 0.1 mL/min gives peak dispersion of 0.04 min x
0.1 mL/min = 0.004 mL = 4 µL]
Ultra-Low Dispersion
The Max-Light Cartridge ULD cell can be used with the G7117A DAD FS and
G7117B DAD. The cell is a requirement for the Ultra-Low Dispersion Kit solution
which currently exists as 1290 Infinity Ultra-Low Dispersion Kit (5067-5189). The
cell should be part of the ultra-low dispersion solution.
