Air Quality Equipment
ObservAir Series Aerosol Black Carbon with CO and NO2
Manufacturer: Distributed Sensing Technologies (DST)
Location: BIO 355 (Field Measurement)
The ObservAir Series Aerosol Black Carbon monitor (n = 8) is an aerosol photometer that continuously draws air through a white fibrous filter with a rotary vane pump, measures the rate of 880 nm radiation attenuated by BC accumulating on the filter, and computes the real-time hourly BC mass concentrations in the air. Housed in a compact weatherproof enclosure, it stores data to the SD memory card and incorporates a 2G cellular modem for wireless communication.
The base model ObservAir Series also includes two sensors to measure gaseous pollutants such as CO and NO2 along with temperature and relative humidity.
Controlled Environmental Chamber for filter weighing
Manufacturer: ets, Electro-Tech Systems, Inc.
Location: BIO 355 (Lab Measurement)
The Air Quality Lab is equipped with a controlled environmental chamber for filter conditioning and weighing. The Model 518 Controlled Environmental Chamber is a completely integrated system, fabricated from 0.375” clear and white acrylic that provides the user with excellent visibility inside the controlled environment section. It incorporates precision automatic humidity and temperature control systems that can control the relative humidity to within 0.5% R.H. and the temperature to within 1.0 °F (0.5 °C) of the desired levels. It is housed on a granite slab, which stabilizes weighing results against environmental vibrations.
It includes glove ports, equipment and sample access doors, circulating fans, lighting and accessory power outlets. The standard chamber is capable of precisely controlling temperatures from <32-122°F (<0-50°C) and humidity from 5-98%. The overall dimensions of the chamber is 47″W x25.5″D x22″H including the controlled compartment.

A TAM IV Microcalorimeter system (TA Instruments) for reaction heat measurement
Working principles
All physical, chemical and biological processes release or absorb heat, and microcalorimeter is a technique developed to directly measure the heat signal. The heat signal can be used to derive quantitative thermodynamics and kinetics data of the process being studied.
Graph 1
Real-time heat signal for adsorption of different phosphorus compounds to solid sorbents using a flow through ampoules.
Graph 2
Enthalpy of enzymatic oxidation reaction measured by isothermal titration of different volumes of the substrate into an enzyme solution, using isothermal titration ampoule.
Capability with accessories currently installed
Sensitivity: heat signal as low as 0.5 W (J/sec) can be measured.
Experiment types: isothermal titration (liquid to liquid or liquid to solid suspension), perfusion (gas or liquid flow through solids), batch experiment (isothermal or temperature scanning);
Sample type and volume: ampoules can accommodate sample volume up to 4 mL, solids at sub-micron sizes can be used in a titration experiment, and solids sized > 0.4 m are required for perfusion experiment, the batch ampoule is highly accommodating to different types of samples;
Reaction condition: temperature between 15 to 90 °C, aqueous solutions (organic solvent may also be used), isothermal or temperature scanning (<1°C/hr).
