Liz Huddle spent the summer
determining the parameters
for an instrument called the mist chamber.
The goal was to increase the efficiency of the mist chamber so
that it could be used in place of a different instrument called a denuder. The
mist chamber is an attractive alternative to the denuder because it is less
time and labor intensive, is less expensive, and could potentially be automated.
Both the mist chamber and denuders were used to test ammonia and nitric acid
concentrations. These are important things to measure because they have the
ability to become a particle. Particles have adverse health effects and can
decrease visibility so it is important to learn about ammonia and nitric acid.
Liz attends the University of Minnesota-twin cities with a major in chemical engineering. Her hobbies include being outside, snowshoeing, hiking, jogging and
playing frisbee. She also enjoys reading and hanging out in coffee shops.
