Introduction
Principle of Operation
Thermo Fisher Scientific is pleased to supply this UV photometric ozone
calibrator. We are committed to the manufacture of instruments exhibiting
high standards of quality, performance, and workmanship. Service personnel
are available for assistance with any questions or problems that may arise in
the use of this calibrator. For more information on servicing, see Chapter 7,
“Servicing”.
Principle of Operation The Model 49i Primary Standard operates on the principle that ozone (O
molecules absorb UV light at a wavelength of 254 nm. The degree to which
the UV light is absorbed is directly related to the ozone concentration as
described by the Beer-Lambert Law:
I
I
o
where:
K = molecular absorption coefficient, 308 cm-1 (at 0°C and 1
atmosphere)
L = length of cell, 38 cm
C = ozone concentration in parts per million (ppm)
I = UV light intensity of sample with ozone (sample gas)
Io = UV light intensity of sample without ozone (reference gas)
KLC−
=e
)

Zero air is supplied to the Model 49i Primary Standard through the zero air
bulkhead and is split into two gas streams, as shown in Figure 1-1. One gas
stream flows through a pressure regulator to the reference solenoid valve to
become the reference gas (I
). The second zero air stream flows through a
o
pressure regulator, ozonator, and manifold to the sample solenoid valve to
become the sample gas (I). Ozone from the manifold is delivered to the
ozone bulkhead. The solenoid valves alternate the reference and sample gas
streams between cells A and B every 10 seconds. When cell A contains
reference gas, cell B contains sample gas and vice versa.
The UV light intensities of each cell are measured by detectors A and B.
When the solenoid valves switch the reference and sample gas streams to
opposite cells, the light intensities are ignored for several seconds to allow
the cells to be flushed. The Model 49i Primary Standard calculates the

Gas Units The Gas Units screen defines how the O
expressed. Gas units of parts per billion (ppb), parts per million (ppm),
micrograms per cubic meter (μg/m3), or milligrams per cubic meter
(mg/m3) are available. The μg/m3 and mg/m3 gas concentration modes are
calculated using a standard pressure of 760 mmHg and a standard
temperature of 20 °C.
When switching the selected units from ppb or ppm to μg/m3 or mg/m3,
the analog ranges all default to the highest range in that mode. For example,
when switching from mg/m3 to ppm, all the ranges default to 5 ppm.
Therefore, whenever you change units, you should also check the range
settings.

Averaging Time
Averaging Time The averaging time defines a time period (10 to 300 seconds) over which
O3 measurements are taken. The average concentration of the readings are
calculated for that time period. The front panel display and analog outputs
are updated every 10 seconds with the calculated averages. An averaging
time of 10 seconds, for example, means that the average concentration of
the last 10 seconds will be output at each update. An averaging time of 300
seconds means that the moving average concentration of the last 300
seconds will be output at each 10-second update. Therefore, the lower the
averaging time, the faster the front panel display and analog outputs respond
to concentration changes. Longer averaging times are typically used to
smooth output data.
The following averaging times are available: 10, 20, 30, 60, 90, 120, 180,
240, and 300 seconds.

O3 Concentration The O
sets the minimum and maximum alarm limits. Acceptable alarm limits
range from 0 to 5,000 ppb. The minimum alarm may be programmed as a
floor trigger (alarm is triggered when the concentration falls below the
minimum value) or a ceiling trigger (alarm is triggered when the
concentration goes above the minimum value). If the O3 concentration
goes beyond either the minimum or maximum limit, an alarm is activated.
The word “ALARM” appears in the Run screen and in the Main Menu.

Pump Pressure The Pump Pressure screen (read only) is used to test the pump. The
solenoids are energized such that there is no flow in Cell B. The flow rate for
Cell B drops to zero and the pressure reading should drop below 390
mmHg in less than 20 seconds. This indicates the effectiveness of the
internal pump. After 20 seconds, if the pressure is greater than 390 mmHg
or the flow is greater than 0.010 LPM, the words “PUMP PROBLEM
DETECTED” appears. After 20 seconds, if the pressure is less than 390
mmHg and the flow is less than 0.010 LPM, the words “PUMP OK”
appears.

Detector Calibration The Detector Calibration screen is used to set the calibration factors for
detector A and detector B. Calibration factors are computed so that both
detectors read 100,000 Hz on zero air. If either detector reads lower than
75,000 Hz or higher than 125,000 Hz, this calibration will not be
successful. It is crucial that the lamp intensity be set such that both detector
intensities fall inside this range before performing this calibration.
