The Slit section allows you to select the optical bandwidth of the detector; the narrower the slit, the smaller the optical bandwidth of the instrument, but the lower its sensitivity. The smaller the optical bandwidth the higher the spectral resolution.
To set the slit width for modules with adjustable slit widths, display the drop-down list and select an appropriate slit width from the list:
G1315A-D and G7115A | 1, 2, 4, 8, 16 nm |
G4212A and G7117B | 1, 2, 4, 8 nm |
G4212B and G7117A/C | 4 nm fixed slit (no drop-down list) |
For an HDR-DAD Cluster with similar detectors (both G4212A, or both G4212B), the Slit setting applies to both detectors. For an HDR-DAD Cluster containing G4212A and G4212B, only the 4 nm Slit setting is available. |
