Swabs for Surface Microbial Sampling
|
|
MoldSense SweepSwab
Common swab, swab-in-a-tube, and nylon-flocked
swab are currently available for indoor surface
microbial sampling. Common swab is designed to
take clinical samples for presence/absence results. It
can be used to collect loose bacteria and mold spores
on a smooth surface. However, its long handle
designed for patient's comfort is too soft and flexible
for collecting mold growth. Its Q-Tip type head also has
limited capacity to collect fungal biomass. The sponge
or gel in the container to keep the swab tip moist will
retain portion of the sample and reduce recovery rate
in laboratory preparation, thus create negative bias in
the results.
Swab-in-a-tube (3M Swab-Sampler) has a short
handle and no sponge or gel in the container. It's
designed for collecting environmental samples.
However, the collection and recovery efficiency is still
limited by the Q-Tip type swab head. MoldSense
SweepSwabs are nylon-flocked swabs, which has a
brush-like head full of small nylon fibers. Both the
collection and recovery efficiency are higher than
common swabs. If quantitative analysis result is
desired, MoldSense SweepSwab is the right choice of
sampling device.

IAQ Radio Episode 99: Bob Wendt - Research Architect
|
|
You have been invited to join a live Community Call.
Host: Joe Hughes/Cliff Zlotnik
Episode Notes: Building Science! Why do buildings
fail? What is being done to solve the problems? How
do we stop IAQ problems before they start? This week
on IAQ Radio we have Bob Wendt a research architect
specializing in building science investigations of
residential buildings. Bob retired from the Oak Ridge
National Laboratory's Buildings Technology Center in
January 2008. He is currently an independent
consultant and an adjunct professor in the Mechanical
Engineering Department of Tuskegee University.
Bob's current activities include research into the
impact of mold and contaminants on residential
building materials that have been subjected to
flooding or other water damage. This work has been
in support of the Department of Homeland Security's
Disaster- Resilient Homes project. Join IAQ Radio
and this weeks special guest to discuss how we can
build better buildings.
