FAQ #11
Q. What is the Ko factor that I use in concentration calculations?
A. The conversion from nl/min to ng/min is easy when using the Ko factor:
Ko = 22.4 / MW
Where:
Ko = desired conversion factor
MW = molecular weight of the pure analyte
Then, E1 = E2 / Ko
Where:
E1 = desired emission rate in ng/min
E2 = emission rate in nl/min
Ko = conversion factor as specified above
