Used by Permission
1. Never drop cylinders or permit them to strike each other violently.
2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of weather
and, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the shade when
located in areas where extreme temperatures are prevalent.
3. The valve protection cap should be left on each cylinder until it has been secured against a wall or bench, or
placed in a cylinder stand, and is ready to be used.
4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be moved by using a
suitable hand-truck.
5. Never tamper with safety devices in valves or cylinders.
6. Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder is
attached to a pressurized system.
7. No part of cylinder should be subjected to a temperature higher than 125
permitted to come in contact with any part of a compressed gas cylinder.
8. Do not place cylinders where they may become part of an electric circuit. When electric arc welding,
precautions must be taken to prevent striking an arc against the cylinder.

DESCRIPTION AND SPECIFICATIONS
1-1 GENERAL DESCRIPTION
The Model 890 Ultraviolet Analyzer is
designed to determine continuously the
concentration of the component of interest
a flowing gaseous mixture. The analyzer is
capable of measurement in the 50 to 5,000
ppm range for SO
.
Cl
2
and 100 to 5,000 ppm for
2
Optical Bench
The ultraviolet source emits a pulsed (30 Hz)
beam of energy. This energy is split by a
beam splitter, each beam being directed to
pairs of detectors before and after the sample
cell.
One of the unique features of the Model 890
is the use of spectrally selective,
“Transflectance”© mirrors. These mirrors
isolate the sample and reference spectral
passbands for the detectors. They reflect
energy below a wavelength region and
transmit the remaining, higher wavelengths,
all with much lower energy loss than the more
commonly used bandpass interference filters.
Four detectors are used in this system, two
before the sample cell (sample before [S
and reference before [R
b]) and two after
(sample after [Sa] and reference after [Ra]).
S
b and Sa receive energy in the specific
wavelength regions depending on the
application (265 to 310 nm for SO
355 nm for Cl
nm region for SO
), Rb and Ra in the 310 to 355
2
and 355 to 400 nm for Cl2.

COI = [f(R
b)-Sb]-[f(Ra)-Sa]
where:
in
Ra, Rb, Sa, Sb = signals from those
detectors so identified
f = attenuation factor for the reference
signal, adjusted to compensate for NO
2
interference.
The sample gas is introduced to the sample
cell, and the COI absorbs ultraviolet energy in
proportion to the concentration in the gas. The
difference between the signals of the
detectors located at both ends of the sample
cell determines the concentration of COI
in
the sample.
Additionally, the adjacent (non-COI
-
absorbing) reference wavelengths are used
as a baseline for measurement and correction
of sample interferent components, particularly
NO

Readout is on a 16-character,
LED-backlighted liquid crystal display. COI
concentration data is presented in parts per

million, percent of composition, or percent of
fullscale. Additionally, 0 to +5 VDC output for
a potentiometric (voltage) recorder and 0 to
20 mA or 4 to 20 mA isolated current output
(maximum load 700 ohms) are provided as
standard.
A case heater with fan assembly maintains
proper operating temperature.
These four detectors measure the component
of interest (COI) concentration and correct for
NO
2 interference and UV lamp fluctuations.
The difference between detector
determinations is the COI concentration,
following this formula:

Linearization
A linearizer, based on a fourth-order
polynomial, is incorporated in the electronic
circuitry. By turning the linearizer ON and
entering the correct coefficients, an output
linear with concentration is obtained.

WARNING
POSSIBLE EXPLOSION HAZARD
This analyzer is of a type capable of analysis of sample gases which may be flammable. If used for analysis of such gases,
the instrument must be protected by a
continuous dilution purge system in accordance with Standard ANSI/NFPA 4961989, Chapter 8.
If explosive gases are introduced into this
analyzer, the sample containment system
must be carefully leak-checked upon installation and before initial startup, during
routine maintenance and any time the integrity of the sample containment system
is broken, to ensure the system is in leakproof condition. Leak-check instructions
are provided in Section 2-8 on page 2-5.
Internal leaks resulting from failure to observe these precautions could result in an
explosion causing death, personal injury
or property damage.

2-6 CALIBRATION GAS REQUIREMENTS
Analyzer calibration consists of setting a zero
point and one or more upscale points.
All applications require a zero standard gas to
set the zero point on the display or recorder
chart. If the factory Calibration and Data
Sheet (included with the drawings at the end
of the manual) specifies a background gas,
use this as the zero gas. If a background gas
is not specified, use dry nitrogen for the zero
gas. Ideally, span gas should be between
75 % and 100 % of the fullscale span.
2-7 SAMPLE HANDLING SYSTEM
Many different sample handling systems are
available, either assembled completely or as
loose components. The type used depends
on the requirements of the particular
application and the preferences of the
individual user. Typically, the sample
handling system incorporates such
components as pumps and valves to permit
selection of sample, zero standard and
upscale standard gas; needle valve in
sample-inlet line for flow adjustment;
flowmeter for flow measurement and/or
indication of flow stoppage; and filter(s) to
remove particulate matter.

2-8 LEAK TEST PROCEDURE
WARNING
POSSIBLE EXPLOSION HAZARD
This analyzer is capable of analyzing sample gases which may be flammable. If
used for analysis of such gases the instrument must be protected by a continuous dilution purge system in accordance
with Standard ANSI/NFPA 496-1989 (Chapter 8).
If explosive gases are introduced into the
analyzer, the sample containment system
must be leak checked upon installation
and before initial startup, during routine
maintenance and any time the integrity of
the sample containment system is broken,
to ensure that the system is in leak proof
condition.
Internal leaks resulting from failure to observe these precautions could result in an
explosion causing death, personal injury
or property damage.
The following test is designed for sample
pressure up to 10 psig (69 kPa).
NOTE
Do not allow test liquid to contaminate cell
or detectors and UV source windows.
Should this occur, follow instructions in
Section 6-1 on page 6-1 to clean the cell.
2-9 SAMPLE FLOW RATE
Recommended sample flow rate is 1 to 2
SCFH (500 to 1000 cc/min). A subnormal
flow rate will not affect readings but may result
in an undesirable time lag. However, an
excessive flow rate can result in cell
pressurization.
Assume that two cell volumes are required to
flush any cell. Approximate flushing time for
the Model 890's 12-inch cell at atmospheric
sampling pressure (i.e., the outlet of the cell
venting to atmosphere) is approximately 12
seconds.
Flushing time is inversely proportional to flow
rate.
The primary effect of flow rate, other than
flushing time, is cell pressure. Due to
restrictions in exit flow configuration, an
increasing flow rate increases sample
pressure in the cell.
1. Supply air or inert gas such as nitrogen at
10 psig (69 kPa) to analyzer via a flow
indicator with a range of 0 to 250 cc/min
and set flow rate at 125 cc/min to the
sample inlet.
2. Seal off sample outlet with a cap.
3. Use a suitable test liquid such as SNOOP
(PN 837801) to detect leaks. Cover all
fittings, seals or possible leak sources.
4. Check for bubbling or foaming which
indicates leakage and repair as required.
Any leakage must be corrected before
introduction of sample and/or application
of electrical power.
Rosemount Analytical Inc. A Division of Emerson Process Management Installation 2-5
In all cases, the effect of pressure on readout
is eliminated if the same flow rate is used for
the measured sample as well as for the zero
gas and span gas.
Note that at higher flow rates the nonlinearity
of the calibration curve increases, because of
increase in sample cell pressure. Therefore, if
higher flow rates are required, the calibration
curve should be redrawn at the higher rate.
At flows up to 2 CFH (1 L/min), gaseous
sample temperatures are equilibrated to
instrument temperature regardless of stream
temperature. At extremely high flow rates,
this may not be true, but no such effect has
been noted up to 18 CFH (9 L/min).
