Gas research

For our gas research we have the following equipment available:

Anemometer

• Temperature and air velocity

Automated gas set-up

A multifunctional and modular set-up with the following capabilities, all of which are controlled by an in-house LabVIEW developed program:

• Adding gaseous pollutants: ethylene, acetaldehyde, methane, NO_x, CO₂, ...
• Adding liquid pollutants: certain higher hydrocarbons (e.g. octane)
• Variable O₂ content
• Variable H₂O content
• Changeable flow rate (0.2 – 3 L/min)
• Possibility to alter reactor configuration

Climate chamber

• Controlled environment (1.2m³) for air purification tests​

DustTrak

• 0.1-10µm particle detection

FTIR Spectrometer

• Online VOC detection (ppm level)
• 2m gas cell and in-situ cell

GC-FID/TCD

• VOC (ppb-ppm level concentrations) detection
• CO₂ detection

GC-PDD

• Low level H₂ measurement

PID

• Total VOC measurement (ppm level)

Pressure sensor + calibrator

• Absolute and differential pressure (-7 to 7 kPa)

P-Track

• 0.02-1 µm particles (ultrafine PM)

Quantum Cascade Laser

• NO, NO₂, N₂O
• CO₂, CO
• NH₃
• Gas cooler for dehumidification

Reactors

• Concentric reactors
