The instruments were based on a nondispersive infrared technique (Carbon Monoxide Analyzer, model 48; Thermo Environmental Instrument Inc., Franklin, MA, USA).
These measurements were collected using a model 48 carbon monoxide analyzer (Thermo Electron Corporation), a model 2000A nitrogen dioxide analyzer (API, San Diego, California), a model 4108 sulfur dioxide analyzer (Dasibi Environmental Corporation, Glendale, California), and a model 1008RS ozone analyzer (Dasibi Environmental Corporation).
To reduce potential misclassification, the level of carbon monoxide in expired after breath will be evaluated in all subjects declaring no traditional cigarette smoking in any phase of the follow-up, using portable carbon monoxide analyzers (Smokerlyzer ® piCO + ™, Bedfont Scientific Ltd).
The level of carbon monoxide in expired after breath will be evaluated in all subjects declaring no traditional cigarette smoking in any follow-up phase, using portable carbon monoxide analyzers.
These ambient measurements were collected using a TEI 48 analyzer (Thermo Environmental Instruments, Franklin, MA) for carbon monoxide, an API 200A analyzer (Teledyne, San Diego, CA) for nitrogen dioxide, a Dasibi 4108 analyzer (Dasibi, Glendale, CA) for sulfur dioxide, and a Dasibi 1008RS analyzer for ozone.
We continuously monitored the air in the exposure chamber for temperature, humidity, nitrogen oxides [chemiluminescence NO-NO2 NOx analyzer; Thermo Environmental Instruments (TEI), Franklin, MA, USA], carbon monoxide (gas filter correlation CO analyzer; TEI) sulfur dioxide (pulsed fluorescence SO2 analyzer; TEI), and ozone (absorption ozone analyzers model 8810; Monitor Labs, San Diego, CA, USA).
We monitored ozone using a continuous ultraviolet photometric analyzer (Teco 49; Teco Diagnostics, Anaheim, CA), carbon monoxide (CO) using a nondispersive infrared analyzer (Teco 48S), nitrogen oxides using a commercial chemiluminescence detector (Teco 42S), and sulfur dioxide (SO2) using a pulsed fluorescence technique (Teco 43S).
The ilmenite ore was isothermally cycled in a pressurized thermogravimetric analyzer using carbon monoxide as a reducing fuel and air as an oxidizing gas.
A microscale combustion calorimeter (MCC) was modified to study gas phase combustion of polymers and flame-retardant plastics by adding carbon monoxide (CO) and carbon dioxide (CO2) analyzers to the standard oxygen (O2) analyzer.
The reductive decomposition of calcium sulfate utilizing both hydrogen and carbon monoxide was investigated using a thermogravimetric analyzer.
The system was equipped with rapid infrared analyzer devices for carbon monoxide (CO) and methane (CH4).
