Moisture…..is the amount of water vapor present in a given sample
It can be expressed in different units>
• Water vapor pressure [mbar]
• Dew point temperature [oC]
• Relative humidity [%]
• Absolute humidity [g/m3dry air]
• Volumetric concentration [ppmv]
• Mixing ratio [g/kg]
• Wet bulb temperature [oC]
Water Molecule
H2O
– One Oxygen atom
– Two Hydrogen atoms
– Mw = 18
– Hydrogen atoms bond to one side of oxygen atom
Polar molecule
Part of the molecule is negatively charged and part positively charged.
Hydrogen atoms in water molecules are attracted to regions of high electron density and can form weak linkages
–Can adsorb to surfaces

• The temperature to which a gas must be cooled where the first molecule of water vapor changes to the liquid
phase.
Dew Point•The temperature to which a gas must be cooled to be saturated with respect to ice (solid water).

• Water vapor rapidly transports through the gold layer and equilibrates to the pore walls of the aluminum oxide layer.
• The number of water molecules adsorbed onto the pore walls determines the conductivity of the pore wall.
• Each value of pore wall resistance provides a distinct value of electrical impedance, which in turn is related to the water vapor pressure.

The system was reading 43 ppmv. Water was injected into the sample line to simulate a process upset. The Aurora immediately picked up the upset immediately. It recovered to within 3 ppmv of the original reading within 3 minutes.
The quartz microbalance did not
recover for several hours.
