3. PRINCIPLE OF OPERATION
The detection of ozone molecules is based on absorption of 254 nm UV light due to
an internal electronic resonance of the O3molecule. The Model 465L uses a
mercury lamp constructed so that a large majority of the light emitted is at the
254nm wavelength. Light from the lamp shines down a hollow quartz tube that is
alternately filled with sample gas, then filled with gas scrubbed to remove ozone.
The ratio of the intensity of light passing through the scrubbed gas to that of the
sample forms a ratio I/Io. This ratio forms the basis for the calculation of the ozone
concentration.
The Beer-Lambert equation, shown below, calculates the concentration of ozone
from the ratio of light intensities.

C
= concentration of ozone in ppb
T = sample temperature in degrees Kelvin
P = pressure in inches of mercury
As can be seen the concentration of ozone depends on more than the intensity ratio.
Temperature and pressure influence the density of the sample. The density changes
the number of ozone molecules in the absorption tube which impacts the amount of
light removed from the light beam. These effects are addressed by directly
measuring temperature and pressure and including their actual values in the
calculation. The absorption coefficient is a number that reflects the inherent ability
of ozone to absorb 254 nm light. Most current measurements place this value at 308
cm-1 atm-1 at STP. The value of this number reflects the fact that ozone is a very
efficient absorber of UV radiation which is why stratospheric ozone protects the life
forms lower in the atmosphere from the harmful effects from solar UV radiation.
Lastly, the absorption path length determines how many molecules are present in the
column of gas in the absorption tube.

Teledyne API Model 465L O3Monitor Operation Manual
18 Teledyne API Model 465L O3Monitor Manual 05509G DCN6806
The intensity of light is converted into a voltage by a high resolution A/D (analog-
to-digital) converter. The digitized signal and other variables are used by the CPU to
compute the concentration using the above formula.
About every 2.5 seconds the 465L completes a measurement cycle consisting of a 1
second wait period for the sample tube to flush, followed by a 150 ms measurement
of the UV light intensity to obtain I. The sample valve is switched to admit scrubbed
sample gas for 1 second, followed by a 150 ms measurement of the UV light
intensity to obtain Io. Measurement of the Ioevery 2.5 seconds eliminates
instrument drift due to changing intensity of the lamp caused by aging and dirt.
