Product Overview Chapter 2 | 7
Fundamental Principles
Silica refers to the reactive silica in pure water, such as
boiler feedwater, deionized water, steam condensate, and
RO permeate used in power plants, boiler or ultrapure
water applications. It is a very important indicator for
detecting and controlling the corrosion or scaling on
turbines, heat exchangers, and boilers. Online real-time
measurement of silica enables safe, efficient operation,
reduces maintenance, and replacement costs due to
scaling. The online silica analyzer allows instantaneous or
automated decisionmaking, enabling removal or recycling
of water with out-of-range silica concentration. Continuous
silica monitoring provides rapid notification of RO
breakdown or saturation of ion exchange resins, thus,
ensuring maximizing system efficiency and minimizing
downtime for repairs. Orion 8030cX Silica Analyzer can
send alerts/alarms or data to warn the users at the onset
of silica spikes, triggering corrective actions and reducing
failure and issues downstream.
Orion 8030cX Silica Analyzer is based on the detection
principle of the Heteropoly-molybdenum blue colorimetric
method. In this process, silica reacts with molybdate in
acidified condition to form siliconmolybdate yellow. This
is an intermediate then reacts with reductant to generate
siliconmolybdate blue. The absorbance of this blue
complex at a specific wavelength is proportional to the
silica content. After calibration, the silica concentration
(unit: µg/L or ppb) in the water sample can be reported.
Interferents such as phosphate (PO43-) and arsenic (As)
can cause significant false-positive errors. Therefore, the
masking reagent R2 is added to prevent formation of
intermediate reaction products which interfere with the
molybdate method, thereby enabling more accurate
results.
Below 30 mg/L, the phosphate (PO43-) and arsenate
(AsO43-) ions will not interfere with silica test results. In
standard boiler water, ultrapure water, Ion exchange resin
effluent, mixed-bed demineralizer effluent and RO
permeate applications, the phosphate (PO43-) and
arsenate (AsO43-) ions will not exceed the 30mg/L
threshold, so the results of 8030cX Silica Analyzer will be
accurate without interference.
Orion 8030cX Silica Analyzer includes the following parts:
the electronic control system and water sample analysis
system.
The electronic control system includes the power supply
module, circuit control system and user interface panel,
and it has the functions of instrument power-on, self-test
and fault alarm. Historical analysis data, alarm data,
calibration and event log are stored in the instrument for
one year or even more, which users can downloadviaUSB
drive. The real-time data can also be transmitted to
external equipment (PLC or DCS) through 0/4-20 mA
output signals or RS485. The user can set the
measurement time, measurement frequency, calibration,
cleaning and validation frequency according to the site-
specific requirements.
The water sample analysis system includes the water
sampling flow cell, reagents delivery sub-system, reaction
cell, and measurement and analysis module. The water
sample and reagents are delivered by a newly designed
fluidic sampling system to ensure a higher measurement
accuracy. The instrument has implemented an accurate
temperature control on the color reaction process to
ensure the colorimetric reaction proceeds to completion.
Optical background correction was implemented to
reduce background interference. Pre-analysis and post-
analysis rinses and cleaning procedure are built in each
measurement to ensure accurate result without carry over
effect or contamination.

Optional Sample Inlet Filter
If the sample source is ultrapure water, no filter is needed.
If sample source is not ultrapure water or it may contain
large particles (e.g. startup of a power plant could release
rusty particles to boiler feedwater), then a pre-filter with
~200 um pore size is needed. Thermo Fisher provides a
prefilter Y-strainer with part # 7070FLT. This filter contains
two adaptors that connect the ½" NTP thread on Y-strainer
to 6mm (or ¼")OD tubing.
To install, put Teflon tape on the thread size of the
adaptors. Screw in one adaptor to one end of the Y-
strainer. Then, loose the nut (cap) on the other side of the
adaptor. Pushin 6mm (or ¼")OD soft tubingto the adaptor
hole and tighten the nut (cap). The other side of the soft
tubing goes to the inlet of the flow cell (in step 1 of flow

Alarm Signal/Relay Wiring
The instrument provides three relays, J6, J7 and J8 (see
Figure 3.6), without voltage contacts through the main
control board. Three contacts: normally open (NO),
normally closed (NC) and common terminal (COM). The
maximum rated capacity of relay contacts is 250V AC, 8A.
The maximum acceptable cable size for the wiring
terminals is 14AWG. Table 3.3 describes J6, J7 and J8
wiring terminals and corresponding functions.

Digital Signal Input Wiring
Two digital input interfaces on the main control board are
used for the external trigger control. Pin 1 and pin 2 of J2
and J3 are inputs. Either external power input or internal
power of the instrument can be used. If external power
input is used, the external power supply shall be 5~24V
DC. If the internal power of the instrument is used,
pin 1 and pin 2 of J1 provide a 24V DC power supply.
Please refer to Figure 3.13 for specific digital power
access. Please refer to Table 3.4 for digital signal input
wiring.
a) Use an internal 24V DC
power supply
b) Use an external power
supply
