    VAC’SCENT Vacuum Chamber is a portable easy to use air sampler with integral pump that creates a negative pressure inside the chamber.  Place your air sample bag(s) inside the chamber and fill without the need for a separate pump.  You will want this convenient case in the field for easy sample collection.  Carry your sample tubing and other tools in the case from sample point to sample point.

    Q: Does the VAC’SCENT comply with EPA sampling methods?
    Yes, EPA Method 18 – Measurement of Gaseous Organic Compound Emissions by Gas Chromatography and Method 0040 – Sampling of Principal Organic Hazardous Constituents from Combustion Sources Using Tedlar Bags.

    Q: When I sample, how do I minimize contamination between samples?
    Change or purge the Teflon sampling tubing after each sample collection.

    Q: Do I need a pump with the VAC’SCENT?
    No, the VAC’SCENT has a pump inside. However, if you need to collect a sample over a long period of time (10-minutes to 60-minutes) we recommend you use a variable speed personal sampling pump externally to create the vacuum inside the VAC’SCENT.

    Q: What sample tubing should I use?
    Teflon tubing should be used for collecting odour samples. St. Croix Sensory can provide you 1/4″ Teflon tubing.

    Q: What are the ports on the chamber?
    There are four ports on the front of the chamber.  Ports A & B (front left) are the integral pump outlet and inlet.  Port C is a valved port for depressurizing the case. Port D is the sample inlet port.  Connecting Port B to Port C will evacuate the air in the case.  The sample will then flow into Port D, and then the sample bag, to balance the pressure.

    Q: What size sample bags will fit in the VAC’SCENT?
    The VAC’SCENT can be used to fill two 10-L sample bags at one time.  This allows for collection of true duplicates.  A 25-L bag can be used if the dimensions of the bag are appropriate.  Please contact us if you have specific needs. The VAC’SCENT can be built with cases of varying sizes.
