1.2. M100E OVERVIEW
The Model 100E (also referred to as M100E) 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 causing 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 M100E’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 that stores SO
2
concentration measurements made 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, 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.
