How to choose the correct guard column?

Hello I would like to purchase a guard column for a zorbax SB Phenyl 4.6 x 150 mm 3.5 micron column.  Could someone help me choose the correct part numbers for the column and cartridges?

  • 863953-912 This is part # of column you have or any other part #....Confirm part #..
  • That is the correct part number for my column.
