The following tables indicate the approximate time
required to evaporate various common solvents. Tables A
and B show the average time required to evaporate 8
samples from the selected beginning volume to a level
where the solvent is at the top of the Cool-Zone stem.
Tables C shows the average time to evaporate various
solvents in different length Cool-Zone stems. It shows the
average time for solvents to evaporate from the top of the
stem to the indicated remaining volume when 8 vials are
run simultaneously. The following example illustrates the
use of the charts:
Assume that a starting volume of 300 ml
methylene chloride is placed in a 600 ml
sample vial with a 1.5 ml stem. The vial is
covered with a cap. The desired endpoint
volume is 0.5 ml. From Table A, the time to
evaporate to the top of the stem is 59
minutes. From Table C, the time to
