Product Description of the 1260 Infinity III SFC Control Module

The Agilent 1260 Infinity II SFC Control Module is responsible for all tasks connected to pre- and post-conditioning of the mobile phase. In contrast, flow rate, mobile phase composition, detection, column temperature and data analysis are controlled by the modules of the Agilent 1260 Infinity II SFC System in combination with the OpenLab CDS software software. This includes metering the carbon dioxide flow and mixing the modifier into the mobile phase by the 1260 Infinity II SFC Binary Pump.

In detail, the Agilent 1260 Infinity II SFC Control Module uses vapor-phase carbon dioxide, redistills it to the liquid state and boosts its pressure to just under the column head pressure. Since the CO₂ gas is a very poor solvent, most contaminants in the carbon dioxide are left in the source, which allows for the use of inexpensive, beverage-grade CO₂, unlike in any other commercially available instrument. The 1260 Infinity SFC Control Module further recollects the effluent from the UV (or other) detector and controls the back-pressure up to 400 bar over the complete system.
