Introduction
Principle of Operation
Thermo Fisher Scientific is pleased to supply this HCl analyzer. 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
analyzer. For more information on servicing, see Chapter 7, “Servicing”.
Principle of Operation
The Model 15i operates on the principle that HCl absorbs infrared
radiation. Because infrared absorption is a non-linear measurement
technique, it is necessary to transform the basic analyzer signal into a linear
output. The Model 15i uses an internally stored calibration curve to
accurately linearize the instrument output over any range up to a
concentration of 5000 ppm.
The sample is drawn into the Model 15i through the sample bulkhead, as
shown in Figure 1–1. The sample flows through the optical bench.
Radiation from an infrared source is chopped and then passed through a
gas filter alternating between HCl and N2. The radiation then passes
through a narrow bandpass interference filter and enters the optical bench
where absorption by the sample gas occurs. The infrared radiation then
exits the optical bench and falls on an infrared detector.
The HCl gas filter acts to produce a reference beam which cannot be
further attenuated by HCl in the sample cell. The N2 side of the filter
wheel is transparent to the infrared radiation and therefore produces a
measurement beam, which can be absorbed by HCl in the cell. The
chopped detector signal is modulated by the alternation between the two
gas filters with an amplitude related to the concentration of HCl in the
sample cell. Other gases do not cause modulation of the detector signal
since they absorb the reference and measure beams equally. Thus, the GFC
system responds specifically to HCl.
The Model 15i outputs the HCl concentration to the front panel display,
the analog outputs, and also makes the data available over the serial or
Ethernet connection.

In the dual range mode, there are two independent analog outputs. These
are labeled simply as the “High Range” and the “Low Range”. Each
channel has its own analog output range, averaging time, and span
coefficient.
This enables the sample concentration reading to be sent to the analog
outputs at two different ranges. For example, the low HCl analog output
can be set to output concentrations from 0 to 50 ppm and the high HCl
analog output set to output concentrations from 0 to 100 ppm.

In addition to each channel having two ranges, each channel has two span
coefficients. There are two span coefficients so that each range can be
calibrated separately. This is necessary if the two ranges are not close to one
another. For example, the low HCl range is set to 0–5 ppm and the high
HCl range is set to 0–5000 ppm.
By default, in the dual range mode, the analog outputs are arranged on the
rear panel connector as shown in Figure 3–5. See Table 3–3 for channels

Auto Range Mode
The auto range mode switches the HCl analog outputs between high and
low ranges, depending on the concentration level. The high and low ranges
are defined in the Range menu.
For example, suppose the low range is set to 50 ppm and the high range is
set to 100 ppm (Figure 3–6). Sample concentrations below 50 ppm are
presented to the low ranges analog outputs and sample concentrations
above 50 ppm are presented to the high ranges analog outputs. When the
low range is active, the status output is at 0 volts. When the high range is
active, the status output is at half of full-scale.
When the high range is active, the concentration must drop to 85% of the
low HCl range for the low range to become active.
In addition to each channel having two ranges, each channel has two span
coefficients. There are two span coefficients so that each range can be
calibrated separately. This is necessary if the two ranges are not close to one
another. For example, the low HCl range is set to 0–5 ppm and the high
HCl range is set to 0–5000 ppm.

Gas Units
The Gas Units screen defines how the HCl concentration reading is
expressed. Gas units of parts per million (ppm) and milligrams per cubic
meter (mg/m3) are available. The mg/m3 gas concentration mode is
calculated using a standard pressure of 760 mmHg and a standard
temperature of 20 °C.
When switching the selected units, 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 5000 ppm. Therefore, whenever you change
units, you should also check the range settings.
● In the Main Menu, choose Range > Gas Units.
Note If the units change from ppm to mg/m3 or vice versa, the instrument
should be re-calibrated, particularly if the user’s standard temperature is
different from 20 °C. A display warning will appear that ranges will be
defaulted and calibration parameters reset. ▲

The Averaging Time screen allows the user to change the averaging time,
which is the time period (1 to 300 seconds) over which HCl measurements
are taken. The average concentration of the readings is calculated for that
time period. The front panel display and analog outputs are updated every
second for averaging times 1, 2, and 5, and every 10 seconds for averaging
times between 10 and 300 seconds. 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
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 Averaging Time screen for the single range mode is shown below. In
the dual and auto range modes, an Averaging Time Menu is displayed
before the averaging time screens. This additional menu is needed because
the dual and auto range modes have two averaging times (high and low).
The Averaging Time screen functions the same way in the single, dual, and
auto range modes. The following averaging times are available: 1, 2, 5, 10,
20, 30, 60, 90, 120, 180, 240, and 300 seconds.

HCl Background
The background correction is determined during zero calibration. The HCl
background is the amount of signal read by the analyzer while sampling
zero air. The background signal is electrical noise. Before the analyzer sets
the HCl reading to zero, it stores this value as the HCl background
correction.
The Background screen is used to perform a manual adjustment of the
instrument’s zero reading. Before performing a manual zero adjustment,
allow the analyzer to sample zero air until stable readings are obtained.The
first line of the display shows the current HCl reading. This reading is the
HCl background signal. The second line of the display shows the HCl
background correction that is stored in memory and is being used to
correct the HCl reading.

In the following example, the analyzer displays 15.80 ppm of HCl while
sampling zero air. The HCl background correction is 0.0 ppm. That is, the
analyzer is not applying a zero background correction. The question mark
is used to indicate that the background value has been changed. In this case
the background correction must be increased to 15.80 ppm in order for the
HCl reading to be at 0 ppm.
To set the HCl reading in the following example to zero, use to

The iSeries instruments include a built-in datalogging capability as a
standard feature. The operator is allowed to create two different types of
records, which for historical reasons, are named lrecs and srecs. Each record
can contain up to 32 different fields, or data items, and records can be
created at user-defined intervals ranging from 1 to 60 minutes.
Record generation is tied to the instrument’s real-time clock. For example,
if the logging period for srecs is set to 30 minutes, a new srec will be
generated on every hour and every half hour (10:00, 10:30, 11:00 …).
Lrecs and srecs function independent of each other. So, for example, an
srec containing just the current HCl level could be generated every 5
minutes while an lrec containing a full set of diagnostic data could be
generated once every hour.
The analyzer's computer system includes three megabytes of flash memory
which is enough to store a full lrec containing 32 data items and a full srec
containing 32 items once each minute for a week (>20,000 total records).
If logging is limited to the minimum content of date, time, HCl
concentration and error flags, the analyzer can store data once each minute
for 4 months (>190,000 total records).
