*Use the flow rate that will give the recommended air volume. Minimum liters generally
refer to the least number of liters that are required to see 0.1 to 0.2 TLV (TWA).
Maximum liters refer to largest number of liters, which may be collected without
significant breakthrough for a compound if present at approximately two times TLV
(TWA) levels. The recommended volumes should be collected even if very low or very
high levels are suspected.
