Why PS-SFC is Cheap

Once the investment is paid, operating costs are much reduced. Eluent is cheap and completely recycled. The price of the packing material depends on the purification case but it is important to note that no special packing is required (all the HPLC packings are currently used in SFC). The energy cost is due to the heating and cooling devices required. 

Thanks to the automation system (included in the investment cost), labor cost is much reduced one operator is required on the basis of 2 or 3 h per day for 24 h per day operations. The miscellaneous part of the cost includes environment, buildings, insurance, administration, etc.
