Notes: * = BAS192 method acquisition parameters of analyses conducted during Leg 197. † = the widths of the entrance and exit slits. ‡ = the increment between points is the interval in nanometers between each of the calculation points in Mode 2, or the calculation window (nanometers) that constitutes the single point in Mode 5. Alk = an increase in sheath gas flow from 0.15-0.2 to 0.8 L/min for analysis of these elements.
