Ser in u s ® 40 U ser M an u al 3 .5 As the activated species NO * reverts to a lower energy state, it emits broad-band radiation from 500 - 3000 nm, with a maximum intensity at approximately 1100 nm. Since one NO molecule is required to form one NO * molecule, the intensity of the Chemiluminescent reaction is directly proportional to the NO concentration within the sample.

Ser in u s ® 40 U ser M an u al 3 .5 1.5.6 Ozone Generator Refer to Figure 2 for the location of Ozone generator. The Ozone generator is a corona discharge Ozone source driven by an ignition coil. Dry air is drawn into the discharge tube via an orifice and ionised by a high voltage electrode.
Page 31: Measurement Cell
1.5.8 Measurement Cell Figure 9 – Measurement Cell 1.5.8.1 PMT Assembly Figure 10 – PMT Assembly Photomultiplier Tube (PMT) Refer to Figure 10 for the location of PMT. The PMT detects the amount of light reaching its sensors. The selective filtering of light reaching the PMT allows for direct measurement of NO reacting with O in the reaction cell.

Page 33: Pneumatic Tubing
Pressure Sensor PCA Refer to Figure 11 for the location of pressure sensor PCA. The pressure sensor PCA has an absolute- pressure transducer that is mounted on the reaction cell and sealed via a gasket. This allows the pressure sensor PCA to measure the sample air pressure in the reaction cell. This pressure reading is used to verify sample flow and correct measurement readings for pressure variations.

5.4.5 Manual Instrument Gain and Offset Adjustments CAUTION Manual adjustment of the Instrument Gain does not take into account the PTF correction and can lead to an incorrect calibration. At times it may be desirable to manually adjust the instrument’s gain and offsets. Typically this option is only used when an instrument calibration has been corrupted and the user wishes to reset the instrument response factors prior to performing a new calibration.

8.11.2 Trace Setup Sighting and System Setup The sensitivity of the Serinus 40 trace requires special materials to be used for all measurement path lines. These materials must be inert to the pollutant being measured as shown below:  Sample Column: The Sample Column should be made of glass to prevent reactions with air drawn into column.
Page 196: Trace Operation
Refer to Section 9.8 for a detailed pneumatic diagram. Pneumatics A standard Serinus 40 instrument uses calibration valves to supply sample, span and zero air to the inlet. The small error created from delivering gas through different lines is not measurable in standard instruments but can offset results in a trace level instrument.
Page 197: Trace Calibration Guidelines
 The Serinus 40 Trace must be used in a laboratory environment which includes air conditioning to stabilise the temperature.  A zero test should be performed over a 24 hour period to get an accurate reading of the Lowest Detectable Limit (LDL) of the entire system installation.
