4 - Photometric measuring cell 9 - Reagent pumps (x4) 14 - Drain pump of measuring cell
5 - Measuring solenoid valve 10 - Reagent canisters (x4)

The 9210 can analyze up to six different samples. The sample to be analyzed circulates in a
fast loop permitting rapid renewal of the sample. Adjustment of the flow is carried out with the
help of a needle valve (2). At the beginning of the analysis, the sample is introduced into the
measuring cell (4) with the use of a solenoid valve (5).

The reagents R1M and R1A are first added using two of the reagent pumps (9). The silica
contained in the sample then reacts with the molybdate and forms the silicomolybdic complex.
The reaction will take up to 5 minutes.

Oxalic acid is then added using a reagent pump (9) to avoid phosphate interference and to
intensify the color.

The silicomolybdic complex is reduced to a blue molybdenum complex by means of ferrous
ions. A photometric measurement is carried out at the end of the reaction.

13

Analyzer Overview

3.2 Calibration

In order to ensure accurate measurements, the analyzer should be calibrated periodically. The
zero is achieved chemically and internally in the analyzer. The system slope is controlled by
comparison to a standard solution of known concentration. Further information regarding
calibrations can be found in the section entitled Calibration on page 51.

3.3 Analyzer outputs

The instrument can measure silica concentration from three different sources:

• the process sample during a normal measuring cycle

• the calibration solution during an automatic calibration

• an external sample during the grab sample operation

Whatever the sample source, the measurement cycle structure is identical and all analyzer
outputs (e.g. 4/20 mA outputs, screen display, RS485 data, alarm status, etc.) are refreshed
during the last minute of the measurement.

3.4 Maintenance

To ensure a high degree of accuracy is maintained by the analyzer, it is recommended to
perform a specific maintenance procedure once a year. All replacement parts and fittings are
available by purchasing the maintenance kit 09120=A=8000 which contains enough parts and
fittings for two years.

Full details on this procedure and the contents of the maintenance kit can be found in Yearly

maintenance on page 60.

Section 4 Installation

WARNING
The analyzer should only be assembled by qualified staff. Mains power should only be
connected once installation has been completed and checked.

4.1 Analyzer inspection and unpacking

The analyzer has been factory tested and checked prior to shipping. We nevertheless
recommend that you perform a visual inspection in order to ensure that it has not been
damaged. Any marked packaging is a potential sign of damage that may not be immediately
visible. Keep all packaging in the event of claims.

Open the box. Take the packing list from the box and check the presence of all the items
selected. If any parts or accessories are missing, refer to your distributor or to Hach Lange.

4.2 Analyzer preparation

Before installing the analyzer, think about the following:

• Place the analyzer close to the sample point. This will allow the response time to be reduced.

• The sample should be homogenous and representative.

• The temperature of the sample should be between 5 and 50°C.

• The pressure of the sample should be between 0.2 and 6 bar and remain relatively stable.

• The solution should be free of particles.

• Sample lines should be in PE/PTFE/FEP (4 x 6 mm).

• Avoid any location with a corrosive atmosphere or subject to liquid spills.

• Chose a dry and dust-free location.

• The ambient temperature of the analyzer should not exceed 45°C. If the temperature is

below 5°C, the analyzer should be installed in a heated cabinet (not provided by Hach
Lange).

21

Installation

4.7 Connecting the drain tube

The drain outlet is located on the bottom of the analyzer. A 12 x 17 mm pipe is delivered with
the analyzer and should be connected to the drain outlet at one end and the other fed to a drain
for sample evacuation.

Note: Evacuation should be free of any mechanical constraints, and any counter-pressure.

4.8 Mains power connection

WARNING
No intervention should be carried out on the analyzer without first switching off the
power.

The electrical installation should be carried out by duly qualified personnel. A supply voltage of
100-240 VAC is acceptable without changing the configuration. The power supply terminals can
be removed from their housing to make connection easier.

For safety reasons, it is imperative to respect the following:

• Use a three-wire power lead (live + neutral + earth) for supplying the required power.

• The analyzer should be connected to the mains via a circuit-breaker or fuse whose value

should be less or equal to 20 A. It should be located in the proximity and be identified.
This connection should cut-off the live and neutral when electrical problems occur or
when the user wishes to intervene inside the analyzer. However, the earth conductor
should always be connected.

Figure 9 Drain connection

22

Installation

The following procedure outlines the steps required to connect power to the analyzer. The main
cabinet should be open with access to the interior:

1. Open the transmitter front

door by unscrewing the

Given that the demineralized water may often have a non-zero silica content, use of one two
methods for determining the nominal silica values of the final calibration solution. On
completion, transfer 2 liters of the solution to the calibration canister labelled CAL.

Note: It is recommended to use demineralized water with a silica content of no more than 5 ppb when
diluting the concentrated solution.

Method 1:

Determine the silica content of the demineralized water by using a laboratory measurement
technique (e.g. Hach Lange laboratory photometer), or by using the grab sample mode of an
accurately calibrated POLYMETRON 9210 if available on site. The concentration value can then
be added to the values in the above table, giving the following revised table when (for example)
using demineralized water with a silica content of 5 ppb (which equates to 2.33 ppb Si):

using a laboratory measurement technique (e.g. Hach Lange laboratory photometer) or by using
the grab sample mode of an accurately calibrated POLYMETRON 9210 if available on site.

4.12 Connecting the canisters

Each reagent tubing is labelled individually and delivered already connected to the analyzer.
They are fed through, and attached to, caps that attach to the reagent canisters. One end of the
tube is fitted with a chemically inert PVC weight that is used to position the tube in the bottom of
the canister.

Connect each cap to its canister:

• Tube R1M to reagent canister labelled R1M: Sodium molybdate

• Tube R1A on reagent canister labelled R1A: Nitric acid

• Tube R2 on reagent canister labelled R2: Oxalic acid

• Tube R3 on reagent canister labelled R3: Sulfuric acid and ferrous ammonium sulfate

Installation

Screw the cap on each canister so that the weight is resting at the bottom of the canister. Put
the canister in the canister holder with the cap towards the exterior as shown in Figure 11
below.

Figure 11 Canisters connected

The canister on the far right of the illustration is the calibration solution. This has a thicker tube
compared to the reagents. Ensure that the cap has also been securely screwed on to this
canister.

At this stage, the analyzer doors can now be closed and locked as access to the interior of the
analyzer is no longer required.

Section 8 Calibration

Before attempting to setup the analyzer, ensure you have read and understood how to enter
and change data fields as described in the section entitled Data Entry on page 33.

8.1 Menu overview

Select the CALIBRATION option from the main menu.

Note: If a PROGRAMMING password has been set (see Code on page 38 for details on how to do this),
you will be required to enter a password to gain access to the main menu. In addition, if a CALIBRATION
password has been set, you will also be required to enter this password to get access to the calibration
menu.

For continued accurate measurements, the analyzer should be calibrated on a regular basis.

Calibrations allow the adjustment of:

• ZERO of the system

• SLOPE of the system

• Both ZERO and SLOPE of the system

The ZERO calibration is performed chemically by the analyzer. In order to avoid the use of
water free of SiO
slope of the system is then calibrated with a standard solution of known concentration of SiO

Three types of calibration are available:

• Primary

• Manual

• Automatic

In addition, the CALIBRATION menu also gives access to the current calibration parameters
and a history of previous calibration results.

5 < x < 50 ppb 48 hours

> 50 ppb > 72 hours

Recommended frequency

For an automatic slope calibration, this screen lets you define
the frequency.

• When the BASE option is set to Day, the WEEK option

sets the calibration day(s).

Ex 1: SMTWTFS, for a daily calibration.
Ex 2: SM*W*FS, for a calibration every day except
Tuesday and Thursday.

• The HOUR option is used to set the time to start the

calibration.

• When the BASE option is set to Hour, the INTERVAL

option sets the frequency of the slope calibration. The
recommended slope calibration frequency is 1 week (168
hours).

8.1.2 Execution primary calibration

A primary calibration is carried out at the factory and is used as a reference for all following
calibrations.

In general, this type of calibration does not need to be repeated unless important changes
have been made to the analyzer.

Important Note: If you feel that a primary calibration is required, please discuss this with your
Hach Lange representative for advice and assistance before performing this type of calibration

on your analyzer.

The primary calibration sets the slope and zero references. All results of further manual or
automatic calibrations will be compared to the zero and slope references set by this
calibration. Large differences will signify an error in the calibration and will be highlighted with
an error message.

The calibration of the slope is defined first, followed by the zero.
Press Esc to abort the calibration and return to the CALIBRATION menu.

The calibration is made in the following stages:

• Sample preparation

Calibration

• Conditioning

• Measurement

• Rinse

A bar graph indicates the calibration progress.

8.1.3 Execution manual calibration

At the end of the calibration, the results are displayed on
screen.

Primary calibration results:

S = value of the slope (ppb / Abs)

O = value of the zero shift in milli-Abs

The default values show a general idea of the standard values
according to the analyzer range (0-1000 or 0-5000 ppb).

• Slope (S) and offset (O) values.

54

8.1.6 Calibration results

At the end of a manual or automatic calibration, the analyzer compares the results with the
primary reference calibration parameters. Depending on the results, you can accept, restart or
cancel the calibration. There are 3 zones:

Calibration

Zone ok

Normal variations compared to the reference values. The new parameters are acceptable.

In automatic mode, the analyzer returns to its measurement cycle. In manual mode, validate
with OK and restart the analyzer (Start function key).

S: XXXXX DD:MM:YY - Slope

O: XXXXX DD:MM:YY - Offset

C: XXXXX DD:MM:YY - Concentration of the sample solution just measured, calculated using

the calibration values from the Last calibration.

Confirmation zone

Abnormal variations compared to the reference values. The new parameters can be accepted
but a warning is displayed and confirmation is required.

In automatic mode, the analyzer does not take the new parameters, but returns to
measurement mode with the previous parameters. In manual mode, you must confirm (Conf)
or cancel (Cancel) to accept or reject the new parameters.

Note: In automatic mode, where the calibration lies within the confirmation zone, the analyzer takes one
measurement and then recalibrates. After 3 successive invalid calibrations, the analyzer waits for the next
programmed date before attempting another calibration.

Rejection zone

Parameters are abnormal. There is a basic problem such as an invalid calibration solution
preparation being used.

In automatic mode, the analyzer stops and triggers a system alarm. In manual mode, you can
Cancel (return to measurement mode with the previous parameters) or Restart the
calibration.

a. Stop the analyzer measuring process by pressing the Stop function key
b. Press the Menu function key and select the MAINTENANCE option

c. Select the EXTENDED STOP option
d. Fill a beaker with 250 mL of demineralized water
e. Open the analyzer to gain access to the reagent and calibration solution canisters
f. Unscrew the caps on the 4 reagent canisters, remove the tube guides from the

canisters and place them in the beaker of demineralized water

g. Unscrew the cap on the calibration solution canister, remove the tube guide from

the canister and place it in a second (empty) beaker. Do not put it in the beaker of
demineralized water containing the reagent tube guides

h. Press OK to start the rinsing process
i. On completion press Esc to exit the process. The measuring cell and reagent

tubes will now be rinsed and empty

j. Disconnect the analyzer from the power source

3. With the analyzer still open, remove the 4 screws holding the pump box cover in place

(item no. 8 in Figure 3 on page 16) and set to one side.

Note: The pump connections are described on the pump box cover. Each pump has an inlet tubing
(from the canister to the pump) and an outlet tubing (from the pump to the measuring cell). The
outlet tubing is also referred to as the injector.

4. Prepare 4 of the injectors (part no. 09210=A=4362 from the maintenance kit). The

process is slightly different depending on the analyzer model in use (sulfuric acid or nitric
acid chemistry).

60

9120 analyzer with sulfuric acid chemistry:

a. The injector is supplied with the ferrule and fitting nut attached. These are not

required, so cut the tubing immediately after the ferule (90° angle) and discard the
ferrule and nut. Do this on all 4 injectors

9120 analyzer with nitric acid chemistry:

a. No action is required and the tubing injectors should be used as supplied in the

maintenance kit

Maintenance

5. Prepare the inlet tubing (part no. 590=050=060 from the maintenance kit). Again, the

process is slightly different depending on the analyzer model in use (sulfuric acid or nitric
acid chemistry).

9120 analyzer with sulfuric acid chemistry:

a. Cut 4 lengths of tubing of 90 cm each and proceed to the step 6

9120 analyzer with nitric acid chemistry:

a. Using a scalpel, cut one end of the tubing to form a point approximately 30mm

long, to enable the tube to be passed through the ferrule:

WARNING
Always take care when using scalpels. Always make tube cuts away from the body
and keep fingers away from the blade.

b. Slide the fitting nut onto the tube. Slide the ferrule over the pointed end and onto

the tube as far as possible without forcing it, and ensuring the PTFE seal is facing
towards the pointed end of the tube:

c. With the aid of long-nosed pliers or similar, pull the pointed tube end through the

ferrule until the PTFE sealing surface has reached the uncut section of the tube.
Keeping the ferrule as perpendicular as possible to the tube will ensure the best
results. Rotate the ferrule around the tube 3 or 4 times to seat the ferrule on the
tube correctly:

d. Using a scalpel, cut the pointed tube end as close to the ferrule as possible,

ensuring the end of the ferrule is not cut:

61

Maintenance

e. The tube assembly is now ready for use:

6. Renew all the reagent tubing.

Important Note: To avoid any contamination, ensure that each tube guide is always

used for the same reagent as it was previously used for. Under no circumstances should
they be interchanged.

Apply the following procedure for one reagent, then repeat for each reagent in turn. For
easier access, start with the reagent pump on the far left (closest to the calibration
pump).

a. Locate the inlet port (nearest to you) and outlet port (farthest from you) of the

pump. Be aware that there is an additional port on each pump between the inlet
and outlet ports but which is not to be used. Disconnect the inlet tubing and the
injector tubing from the pump. Pull the injector tubing out of its position in the
photometric cell (item no. 5 in Figure 2 on page 15) and discard it

b. Mount the newly prepared injector on the outlet port of the pump and screw in

place. Slide the other end of the tubing through the panel cut-out at the front but
do not yet connect to the photometric cell

c. Mount the newly prepared inlet tubing on the inlet port of the pump and screw in

place

d. Retrieve the old inlet tubing and the tube guide from the beaker of water
e. Unscrew the plastic fitting from the weight (position 1 in the illustration below) and

put the weight to one side on a clean tissue

f. Once the weight is removed, pull all the old reagent tubing out of the tube guide

and discard

g. Slide the newly prepared reagent tubing through tube guide
h. Place a new fitting (part no. 589=010=015 from the maintenance kit) on the end of

the tubing and screw into the weight

i. Take the same sticker as the original one (part no. 625=065=025 from the

maintenance kit) and place it around the reagent tube approximately 10cm from
the tube guide

j. Place the tube guide assembly back in its canister and screw down securely
k. Repeat these steps for the next reagent pump until all four have been completed

7. Change the magnetic stirrer in the photometer cell by first removing the 4 screws from

the photometric cell cover. Put the screws to one side. Lift off the cap and then remove
the old magnetic stirrer in the bottom of the cell.

Take a new stirrer (226=003=013 from the maintenance kit) and place in position at the
bottom of the cell.

Replace the photometric cell cover and secure with the 4 screws.

8. Place the ends of the injectors into the top of the photometric cell as far as they will go

without forcing them.

Material Safety Data Sheets (MSDS)

FIRE FIGHTING MEASURES

FIRE Not combustible, but substance is a strong oxidizer and its

heat of reaction with reducing agents or combustibles may
cause ignition. Can react with metals to release flammable
hydrogen gas.

EXPLOSION Reacts explosively with combustible organic or readily

oxidizable materials such as: alcohols, turpentine, charcoal,
organic refuse, metal powder, hydrogen sulfide, etc. Reacts
with most metals to release hydrogen gas which can form
explosive mixtures with air.

FIRE EXTINGUISHING MEDIA Water spray may be used to keep fire exposed containers

cool. Do not get water inside container.

SPECIAL INFORMATION Increases the flammability of combustible, organic and readily

oxidizable materials. In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing
apparatus with full face piece operated in the pressure
demand or other positive pressure mode.

MEASURES IN CASE OF SPILLAGE

Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area.
Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Neutralize with
alkaline material (soda ash, lime), then absorb with an inert material (e.g. vermiculite, dry sand, earth), and place in a chemical
waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! US Regulations (CERCLA)
require reporting spills and releases to soil, water and air in excess of reportable quantities.

HANDLING AND STORAGE

Store in a cool, dry, ventilated storage area with acid resistant floors and good drainage. Protect from physical damage. Keep
out of direct sunlight and away from heat, water, and incompatible materials. Do not wash out container and use it for other
purposes. When diluting, the acid should always be added slowly to water and in small amounts. Never use hot water and
never add water to the acid. Water added to acid can cause uncontrolled boiling and splashing. Containers of this material
may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed
for the product.

EXPOSURE CONTROLS / INDIVIDUAL PROTECTION

AIRBORNE EXPOSURE LIMITS OSHA Permissible Exposure Limit (PEL):

2 ppm (TWA), 4 ppm (STEL)

ACGIH Threshold Limit Value (TLV):

2 ppm (TWA); 4 ppm (STEL)

VENTILATION SYSTEM A system of local and/or general exhaust is recommended to

keep employee exposures below the Airborne Exposure
Limits. Local exhaust ventilation is generally preferred
because it can control the emissions of the contaminant at its
source, preventing dispersion of it into the general work area.
Please refer to the ACGIH document, Industrial Ventilation, A
Manual of Recommended Practices, most recent edition, for
details.

PERSONAL RESPIRATORS (NIOSH APPROVED) If the exposure limit is exceeded, wear a supplied air, full face

piece respirator, air-lined hood, or full face piece
self-contained breathing apparatus. Nitric acid is an oxidizer
and should not come in contact with cartridges and canisters
that contain oxidizable materials, such as activated charcoal.
Canister-type respirators using sorbents are ineffective.

SKIN PROTECTION Wear impervious protective clothing, including boots, gloves,

lab coat, apron or coveralls, as appropriate, to prevent skin
contact.

EYE PROTECTION Use chemical safety goggles and/or a full face shield where

splashing is possible. Maintain eye wash fountain and
quick-drench facilities in work area.

FIRE FIGHTING MEASURES

FIRE Auto-ignition temperature

Flammable limits in air % by volume
EXPLOSION Flammable vapors may accumulate in confined spaces.
FIRE EXTINGUISHING MEDIA Use any means suitable for extinguishing surrounding fire.

Use water spray to blanket fire, cool fire exposed containers,
and to flush non-ignited spills or vapors away from fire.

SPECIAL INFORMATION In the event of a fire, wear full protective clothing and

NIOSH-approved self-contained breathing apparatus with full
face piece operated in the pressure demand or other positive
pressure mode.

MEASURES IN CASE OF SPILLAGE

Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill. Wear appropriate personal
protective equipment as specified in Section 8. Contain and recover liquid when possible. Do not flush caustic residues to the
sewer. Residues from spills can be diluted with water, neutralized with dilute acid such as acetic, hydrochloric or sulfuric.
Absorb neutralized caustic residue on clay, vermiculite or other inert substance and package in a suitable container for
disposal.

HANDLING AND STORAGE

Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Separate from
incompatibilities. Store below 25C. Protect from direct sunlight. Containers of this material may be hazardous when empty
since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.

EXPOSURE CONTROLS / INDIVIDUAL PROTECTION

AIRBORNE EXPOSURE LIMITS OSHA Permissible Exposure Limit (PEL):

50 ppm (NH3)

ACGIH Threshold Limit Value (TLV):

25 ppm (NH

VENTILATION SYSTEM A system of local and/or general exhaust is recommended to

keep employee exposures below the Airborne Exposure
Limits. Local exhaust ventilation is generally preferred
because it can control the emissions of the contaminant at its
source, preventing dispersion of it into the general work area.
Please refer to the ACGIH document, Industrial Ventilation, A
Manual of Recommended Practices, most recent edition, for
details.

PERSONAL RESPIRATORS (NIOSH APPROVED) If the exposure limit is exceeded and engineering controls are

not feasible, a full face piece respirator with an
ammonia/methylamine cartridge may be worn up to 50 times
the exposure limit or the maximum use concentration
specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. For emergencies or instances
where the exposure levels are not known, use a full face
piece positive-pressure, air-supplied respirator. WARNING:
Air purifying respirators do not protect workers in
oxygen-deficient atmospheres.

SKIN PROTECTION Wear impervious protective clothing, including boots, gloves,

lab coat, apron or coveralls, as appropriate, to prevent skin
contact. Neoprene and nitrile rubber are recommended
materials. Polyvinyl alcohol is not recommended.

EYE PROTECTION Use chemical safety goggles and/or full face shield where

dusting or splashing of solutions is possible. Maintain eye
wash fountain and quick-drench facilities in work area.
