If you follow our Operating and Instruction Manual for CElixir-SDS™, the coating solution (Initiator (A)) is used only once (1) per day or when a new capillary is used. Once you coat your capillary and remove the autosampler vial from the instrument and return the solution to a fresh, clean vial with a solid, inert cap, the remaining solution should be good for up to 30 more coatings. If the solution is stored properly (do not refrigerate) it should be good for many weeks or months.
