5 Optimizing the Detector
Optimization Overview
Choosing a Flow Cell
Several flavors of the Max-Light Cartridge Flow Cell are available, see (Table 7
on page 80).
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]
High Sensitiviy
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).
