airmoPURE - Model D -High Purity Air Generator

The airmoPure provides zero air for :

• FID detector: 180 ml/min
• Pneumatic valve : 60 ml by commutation
• Permapure : 150 ml/min
• Flow in the cooling box ( Pelletier effect): 13 ml/min Dilution of permeation tube for calibration: 50mL/min in continuous mode
• Carrier gas for MEDOR

The airmoPure includes :

• A compressor fixed and a 4-liter cylinder at 7 bars which delivers outlet pressure at 3 bars.
• A membrane air dryer with automatic purge .The air is dried before being compressed in the cylinder.
• A heated catalyser to eliminate hydrocarbons at PPT level
• Connections between the airmoPURE and the instrument

• 180 ml/min for FID
• 50 ml/min in continious for Calibration
• Dilution: 230 ml/min in discontinuous mode (during calibration only)
• Benzene permeation tube (32 ng/min ± 10% at 45°C) diluted at 230 ml/min = 139 μg/m3 or 37 ppb
• Zero air for analysis in continuous mode (airmoBTX /CALIB): 180 + 50 ≈ 230 ml/min
• Zero air for analysis in discontinuous (airmoBTX/CALIB): 180 + 230 ≈ 410 ml/min

• Zero air total hydrocarbon concentration:
• < 0.1 ppb NMTHC in ambient air without poltion
• Dew point:
• < -15°C°
• Zero air maximum flow:
• 1 l/min in discontinuous mode for airmOzone
• Noise:
