Particle Counter

Used for testing particles suspended in the air, sizes range from 0.03 microns to 5.0 microns.

These are all sizes that can be breathed into the lungs.

Q-Trak

The Q-Trak is used to measure the temperature, relative humidity (RH%), Carbon monoxide (CO) and Carbon dioxide (CO2).

Andersen Air Sampler with Pump

An Andersen N-6 Air Sampler set up for air sampling.
Notice the pump midway down the tripod. This pump is calibrated each time testing is done on a different site. The calibration sets the rate at which the air is pulled into the sampling stage located at the top of the tripod. Generally, that rate is 28.3 liters per minute.

Malt Extract Media Plate after Impaction

This is a view of one type of culture plate used in the Andersen Sampler to take air cultures. Notice the dimple-like indentations in the Malt Extract media - these are everything that was in the air pulled into the pump at the time of the test.

When incubated at the right temperature, it will grow any bacteria or mold that was impacted onto the plate.

Zefon Pump with Cassette

This is a Zefon Pump used to take nonviable air samples of contaminants in the air.

In the cassette located at the top of the pole is a small, sticky slide which collects any particles pulled into the cassette when the pump is operating.

The air flow rate for this pump is 15 liters per minute. After impaction, the slide can be viewed under a microscope to identify the particulates.

Air O Cell Cassette

The Air-O-Cell Cassette is used with the Zefon Pump to test for non-viable particulates in the air.

Assorted Testing Materials

1. Malt Extract Plate (used in testing for microbial growth).
2. TSA Plate (used in testing for bacteria).
3. Cellulose Plate (used in testing for Stachybotrys).
4. Air-O-Cell Cassette (used in testing for nonviable particulates).
5. Sterile Swab (for taking samples of visible mold or in ductwork).
6. Microscope slides (tape samples are placed on slide for microscopic identification).
7. Tape (for taking samples in ductwork or any accumulation of particles that are questionable.
8. Stop Watch (for timing of air sampling tests).
