Large-scale chamber facility simulating a residential environment

• Dual 50-m³ compartments housed within a conditioned building
• Individual air handling systems with particle/gaseous contaminant filtration and inlet air temperature and flow rate control
• Dedicated data systems, SF₆ tracer-gas system for ventilation rate measurements, and ozone generator
• Sampling equipment for gaseous and particulate pollutants including electronic mass flow controllers, and real-time particle characterization instrumentation
• Smoking machines and cigarette-handling carousel (photo, lower left) for ETS studies

Large-scale stainless steel chamber facility

• 20-m³ chamber constructed with low VOC-emitting materials housed within a conditioned laboratory
• Air handling system with gas with particle/gaseous contaminant filtration and inlet air temperature, humidity and flow rate control
  

Small-scale chamber facility

• Small-scale stainless steel chambers housed in incubator with associated material conditioning facility
• Clean inlet gas with temperature, humidity and flow rate control; data system and ozone generator with control
  

Analytical Instrumentation

• GC/MS system equipped with Chrompack CP4020 thermal desorber/concentrator for analysis of VOC sorbent tubes
• HPLC system with diode array UV detector and dual fluorescence detectors for analysis of PAH
• Various GCs with flame ionization, photo ionization, nitrogen/phosphorus and Thermal Energy Analyzer detectors
  

Field Sampling and Monitoring Equipment

• A package of personal exposure and area monitoring equipment consisting of CO monitors (Langan Products), programmable air sampling pumps modified for extended operation (Airchek 2000, SKC Inc.) and size-selective impactors (PEM, MSP Corp.).
• Integrated Organic Gas and Particle Samplers (IOGAPS) and associated sample pumps (in photo). This artifact-free sampler designed at LBNL operates at up to 100 L min^-1 and captures semi-volatile and particulate organic pollutants for quantitative gas/particle partitioning and exposure assessment.
• An array of real-time particle characterization instrumentation including laser particle counters and aethalometers
