For sampling events above 3000 feet, reduce flow rate by 15%. MicrovalvesTM are recommended for use on SiloniteTM Canisters and MinicansTM upto 3.2L. Larger Canisters with MicroValvesTM may require longer clearing time due to the added restriction of the valve. the Toxic Organics ValveTM can be used with all canister sizes with the exception of 600mL.

The 600mL MinicanTM with an integrated Micro-QT2TM valve is designed only for MicroValveTM connections.

The following tables shows the target flow rates of various canister sizes and sampling durations.
