1.3 Nomenclature
NO:
Nitrogen oxide or nitric oxide.
NO2:
Nitrogen dioxide.
NOX:
A generic term for mono-nitrogen oxides NO and
NO2.
NH3:
Ammonia
NX
A generic term for mono-nitrogen oxides NO and
NO2and Ammonia
Span:
A gas sample of known composition and
concentration used to calibrate/check the response
of the instrument.
Zero:
Zero calibration uses zero air (NOX/NH3scrubbed
ambient air) to calibrate/check the zero response of
the instrument.
Background Cycle:
Removes unwanted signal from the measurement
signal. This is accomplished by pre-reacting the
sample gas with ozone outside the reaction cell. The
pre-reacted gas is drawn into the reaction cell where
this signal is stored as the background signal. This
background measurement is used to correct the
sample measurement by subtracting the background
signal from the measurement signal. Background
cycle can be described as a dynamic zero where
unwanted signals generated from the
photomultiplier tube (detector) due to internal
offsets (dark current) or unwanted cell
luminescence’s are removed.
Multipoint Precision Check:
A procedure to verify the linearity of the instrument.
Calibration:
The process of adjusting the instrument to ensure
that it is measuring the correct concentration.

Serinus 44 User Manual 3.0
Page 20
Zero Drift:
The changes in instrument response to zero
pollutant concentration over time.
Zero Air:
Is purified air in which the concentration of NO is
<0.5 ppb and NO2is <0.5 ppb with water vapour of
less than 10% RH. Sufficient purified air can be
obtained by passing dry ambient air through an
activated charcoal scrubber, a Purafil scrubber and a
particulate filter.
External Span Source:
Span gas that is delivered via an external accredited
cylinder containing NO in balance with N2(e.g.
NATA/NIST).
Sample Air:
Sample air is defined as the sample before it has
entered the reaction cell, as distinguished from the
exhaust air.
Exhaust Air:
Exhaust air is the sample air after it has passed
through the reaction/measurement/detection cell
and is moving towards being expelled from the
instrument.
ID and OD:
These are measurements of tubing, ID is the internal
diameter of tubing, and OD is the outer diameter.
Multidrop:
A configuration of multiple instruments connected
via the same RS232 cable.
Photomultiplier Tube:
A highly sensitive device which can detect extremely
low levels of light (photons) and multiply the
electrical signal to a point where it can be accurately
measured. These are often called PMT’s for short.
Bootloader:
A program that checks whether the current
firmware is valid and executes the instrument start-
up. The Bootloader can be entered by pressing the
‘+’ key on the front keypad during the first ½ second
after power on, and following the prompts. The
Bootloader enables various low level recovery tools,
including updating the main firmware from a USB
stick.
PCA:
Printed Circuit Assembly. An electronic circuit
mounted on a printed circuit board to perform a
specific electronic function.
slpm:
Standard litres per minute. This is the flow
referenced to standard temperature and pressure
conditions. For the purposes of this manual, all flows
are referenced to 0 °C and 101.3 kpa (1 atm).
