INTRODUCTION, FEATURES AND OPTIONS
This section provides an overview of the Model T100 Analyzer, its features and its
options, followed by a description of how this user manual is arranged.
1.1. T100 OVERVIEW
The Model T100 (also referred to as T100) UV Fluorescence SO
2
Analyzer is a
microprocessor controlled analyzer that determines the concentration of sulfur dioxide
(SO
2
), in a sample gas drawn through the instrument’s sample chamber where it is
exposed to ultraviolet light, which causes any SO
2
present to fluoresce. The instrument
measures the amount of fluorescence to determine the amount of SO
2
present in the
sample gas.
The T100’s exceptional stability is achieved with the use of an optical shutter to
compensate for sensor drift and a reference detector to correct for changes in UV lamp
intensity. Additionally an advanced optical design combined with a special scrubber,
called a "kicker" that removes hydrocarbons (which fluoresces similarly to SO
2
)
prevents inaccuracies due to interferents.
Calibration of the instrument is performed in software which stores SO
2
concentration
measurements made gas with when specific, known concentrations of SO
2
are supplied
to the analyzer. The microprocessor uses these calibration values along with other
performance parameters such as the sensor offset, UV lamp intensity and the amount of
stray light present and measurements of the temperature and pressure of the sample gas
to compute the final SO
2
concentration.
Built-in data acquisition capability, using the analyzer's internal memory, allows the
logging of multiple parameters including averaged or instantaneous concentration
values, calibration data, and operating parameters such as pressure and flow rate. Stored
data are easily retrieved through the serial port or optional Ethernet port via our
APICOM software or from the front panel, allowing operators to perform predictive
diagnostics and enhanced data analysis by tracking parameter trends. Multiple
averaging periods of one minute to 365 days are available for over a period of one year.
