Section 11.13.4 of Method 3620C states, "Elute the column with 60 mL of methylene chloride / acetonitrile / hexane (50/0.035/49.65, v/v/v), collecting the eluate in a second flask. This is Fraction 2." If the middle number were 0.35 instead of 0.035, the total of the three would be 100. Is this just a typo?
That is a typo, which was corrected in the Update V version of the method. The correct entry for acetonitrile should be 0.35, not 0.035.
