However, a customer has supplied a method where 22 mL vials are to be used. Would this 2 mL difference in volume be significant? The sample volume is approx' 2 mL. If it is significant, would it be reasonable to adjust the sample prep' to 91% of original the original volume, i.e. 1.82 mL instead of 2 mL (20 mL = 91% of 22 mL). Thanks in advance.
