MiniVac Canisters

Canisters with a typical volume of six liters have been used extensively for sampling VOCs (EPA Methods TO-14A and TO-15). SKC MiniVac® Canisters combine the benefits of larger canister sampling with small, lightweight 400-ml and 1-L canisters that can be placed at a sampling site for area sampling or attached to a worker's belt for personal sampling. SKC 400-ml and 1-L stainless steel MiniVac Canisters are optimized for personal, indoor air, and source VOC sampling from 1 ppb to 10,000 ppm.

Using MiniVac Canisters

Ensure the canister is certified clean and evacuated. Connect the canister to a flow controller if time-integrated samples are desired or simply open it for grab sampling. Attach the canister at a sampling site or onto a worker's belt and allow it to fill. The canister will stop filling when it reaches equilibrium with external atmospheric pressure. Ship the canister with sample to a laboratory for analysis and subsequent cleaning.

The Sulfinert Difference

The interior of a standard MiniVac Canister is electro-polished (proprietary process-Summa equivalent) for inertness. For ultimate stability, use canisters with a Sulfinert-treated interior to collect and store reduced sulfur-containing analytes.

MiniVac Canister Applications

• Indoor air investigations
• Personal sampling
• Emergency response
• Soil gas sampling

MiniVac Canisters vs Larger-volume Canisters

Small, lightweight MiniVac Canisters complement existing larger volume canisters. The application determines which volume of canister to use.

• MiniVac Canisters (400 and 1000 ml) are used for more concentrated samples such as soil gas.
  
• 3 and 6-liter canisters are typically used to collect integrated (TWA) ambient air samples at sampling times of up to 24 hours.
  
• 15-liter canisters are used for reference standards.
