The Aperture should be installed for light-sensitive samples, which are likely to undergo photodegradation.
The Aperture reduces the intensity of the light entering the cell and thus limits the photodegradation effects.
The use of the Aperture increases the detector noise; for this reason, the use of the aperture is recommended for the light-sensitive samples only.
The flow cell performance without the installed Aperture is the same as of the standard Max-Light Cartridge Cell 10 mm.
To install the Aperture, simply screw it on the light inlet of the G7117-60020 (Max-Light Cartridge Cell LSS (10 mm, V(σ) 1.0 μL)) . Do not apply any tools to affix the Aperture. Finger-tight fixation is enough. Make sure that the Aperture is aligned with the light path and does not obstruct the light path (not tilted in relation to the light axis). Check that after installation, the light intensity is approximately 10 % of the original.
Store the Aperture in a clean environment protected from dust. During installation and deinstallation wear powder-free gloves to protect the Aperture from possible contamination.
When performing detector tests in Lab Advisor, remove the Aperture.
Aperture is not compatible with other Max-Light Cartridges. It can only be installed on the G7117-60020 (Max-Light Cartridge Cell LSS (10 mm, V(σ) 1.0 μL)) .
