3.3 Reagents

3.3.1 Reagents for Ganimede P

The GCA 100 reagents for the automated orthophosphate and total phosphate
determination are designed for 100 determinations. The principle of the reaction complies
with DIN EN 1189 of December 1996.

Phosphate ions react in acid solution with molybdate and antimony ions to form an
antimony–phosphomolybdate complex that is reduced to phosphorus molybdenum blue
by means of ascorbic acid.

The opened solutions can be kept for seven days at room temperature.

Prepare the reagents according to the work instructions enclosed in the reagent
packaging.

28

NOTICE

The Ganimede P and the ready-to-use GaniChem-P GCA 100 reagent kit are optimally adapted
for each another. The use of third-party chemicals can result in the impairment of the results and
the whole system.

The guarantee claim only remains valid with the use of GaniChem-P GCA 100.

3.3.2 Reagents for Ganimede N

The GCA 200 reagents for the automated sum determination of inorganically and
organically bound nitrogen are each designed for 100 determinations.

Inorganically and organically bound nitrogen is oxidized to nitrate with peroxodisulfate by
means of an alkaline digestion. The nitrate content is photometrically measured by means
of UV self-absorption in a differential measurement at 210

The opened solutions can be kept for seven days at room temperature.

Prepare the reagents according to the work instructions enclosed in the reagent
packaging.

The analysis unit N and the ready-to-use GaniChem-N GCA 200 reagent kit are adapted

NOTICE

The reagents remain in the analysis unit when the Ganimede is used daily.

3.3.4 Reagents reserve

A package of GCA 100 for Ganimede P or GCA 200 for Ganimede N is designed for
100

single analyses, and appropriate pre-rinsing amounts for 4–5 analysis series are
included per package. The maximum number of determinations can be reduced from 100
in the event of a higher number of analysis series per package.

A waste bottle can hold the reagent waste and sample waste of one package (i.e. 100
single determinations).

The exact reagent reserves of the chemicals can be shown by means of the menu items
OPTIONS, REAGENT STATUS.

3.4 Ganimede P sample preparation

• Samples must lie within the pH range 2–10.

• Samples that contain substances that react aggressively with Viton, e.g. solvents,

must be diluted.

• Samples containing particulates must be homogenized with a disintegrator for 30

seconds.

• Homogenized samples in positions 1 to 27 can be stirred with magnetic rods with the

sample tray for 36 sample containers.

• The sample containers are suitable for one-time use only. Residues of cleaning

agents can lead to increased phosphate findings.

3.4.1 Load the sample tray

Each sample tray is a sample batch.

If multi-point calibration is to be used, a standard curve with 2–11 measurement points
must be recorded before the measurement series. The device refers to this recorded
curve during measurement operation.

29

Installation

Alternatively, it is possible to work with a two-point calibration. In addition, a zero standard
solution, or alternatively two standard solutions, is/are positioned in positions 35 and 36.

To do so, load the sample tray as follows:

• According to the sample batch, the sample tray is loaded with the samples from
position 1.

• For a two-point calibration, the standards are positioned with the measurement series
on a sample tray for 36 sample containers as follows:

Position 35: GCZ 100 zero solution

Position 36: standard, e.g. 0.2 mg/L PO

-P GCS 050

4

Alternatively:

Position 35: 1st standard, e.g. 0.2 mg/L PO

Position 36: 2nd standard, e.g. 2 mg/L PO

-P GCS 050

Single and double determinations can be carried out. For double determinations, the
sample is drawn from a container twice. The settings refer to the whole sample tray.

Two sample containers must be filled with the sample if the orthophosphate and total
phosphate content is to be determined from a sample. The allocation of the determination
method (orthophosphate or total P) to the position numbers of the sample containers is
performed during definition of the sample batch with the open-loop control unit. If
necessary, the use of the sample tray for 53 sample containers is recommended.

The following table and illustration show an example of a sample tray load for a two-point
calibration:

Section 4 Operation

4.1 Operation of the open-loop control unit

The sample batch is defined with the open-loop control unit according to:

• Parameter (phosphate with Ganimede P or nitrogen with Ganimede N)

• Number of samples

• Single or double determination

• Orthophosphate or total phosphate determination with Ganimede P

or low or high measurement range with Ganimede N

• Analysis as PO

• Dilution factor

• User etc.

Defined sample batches can be saved and retrieved again, modified or copied at any time.
Thus, a new definition of repeated sample batches is omitted.

A two-point calibration, or alternatively a multi-point calibration, can be used in
measurement operation.

For a multi-point calibration, a standard curve must be recorded before the measurement
series. At least five standards are prescribed according to DIN. Optionally, an individual
standard curve is also possible with 2–11 measurement points. The device refers to this
recorded curve during measurement operation if desired.

Alternatively, a two-point calibration can be used during a measurement series with
Ganimede P. To do so, a zero solution (GCZ 100) and a standard are positioned in
positions 35 and 36, or alternatively two different standard solutions.

With Ganimede N, a two-point calibration is used by positioning two standard solutions for
the low and high measurement ranges in each position from 33 to 36.

The operation of the open-loop control unit is carried out via an external keypad or via the
alphanumeric keys of the open-loop control unit. The color graphical display shows the
operation of the different menu levels. Error messages, erroneous entries and abnormal
measurements are presented in color.

connection via the IR interface is established again, the measurement results are
transmitted and displayed as a table in the open-loop control unit.

If the sample batch is processed completely and all data is sent, the connection is
disconnected automatically. The measurement results can be displayed, edited and sent

Section 5 Maintenance

5.1 Sample changer

The sample changer must be disconnected from the mains during cleaning. The PTFE sealing
rings in the housing on the sample arm, on the rinsing vessel and the sealing ring on the tray
holder must not be removed!

Further repairs can only be carried out by the manufacturer's service departments.

The sample changer is a maintenance-free device. For safe and accurate operation, it is
necessary to keep the device clean. A soft cloth that is moistened with water should be
used for (external) cleaning. It must be made sure that no fluid penetrates the device
during cleaning!

In the event of an overflow of the rinsing vessel or spillage of small amounts of liquid over
the sample changer, the sample changer must be switched off (the power plug must then
be disconnected!) and cleaned (in order to dry it). If larger quantities of liquid enter into the
device, it must be made sure that the device is dried completely before switching it back
on.

5.2 Open-loop control unit

DANGER

The open-loop control unit is cleaned with a soft cloth that is moistened with water.

Further repairs can only be carried out by the manufacturer's service departments.

5.3 Analysis unit

Under no circumstances may the digestion cuvette and its supply and drainage lines be opened
or manipulated.

If an over-pressure is intercepted by the dual protection system, the analysis unit must be
switched off and the service department must be informed in order to avert damage to the device.

Burn hazard
Only remove the cover with the power plug pulled out and with a cooling time of a few minutes.

All defects that cannot be repaired by means of a tube change or by means of cleaning the
analysis cuvette, may only be repaired by the service personnel authorized by the
manufacturer.

For the cleaning of the cuvette and for the tube change, it is necessary to remove the
cover in the middle of the device with the lateral knurled screws.

DANGER

DANGER

5.3.1 Mount the cover

1. Hook the cover onto the upper housing edge.

2. Guide the tubes into the recesses on the right and left.

5.3.2 Downtime

In the event of downtime, e.g. overnight or over weekends, a rinse of the system with
cleaning solution (GCR 100) must be carried out.

1. In each case, remove a reagent bottle and seal it with the original lid of the same
color.

The opened reagents are stored in the refrigerator.

Note: The opened reagents can be kept for a maximum of seven days at room temperature.

2. Connect the bottles with cleaning solutions to the corresponding lids.

3. Check the capacity of the waste bottle.

4. Start the rinse process with the open-loop control unit.

The process is finished after four minutes and the system can be switched off.

Section 9 Warranty and liability

The manufacturer warrants that the product supplied is free of material and manufacturing
defects and undertakes the obligation to repair or replace any defective parts at zero cost.

The warranty period for instruments is 24 months. If a service contract is taken out within
6

months of purchase, the warranty period is extended to 60 months.

With the exclusion of further claims, the supplier is liable for defects including the lack of
assured properties as follows: All those parts that, within the warranty period calculated
from the day of the transfer of risk, can be demonstrated to have become unusable or that
can only be used with significant limitations due to a situation present prior to the transfer
of risk, in particular due to incorrect design, poor materials or inadequate finish will be
improved or replaced, at the supplier's discretion. At the discretion of the supplier, these
deficiencies will be corrected or the instrument replaced. The identification of such defects
must be notified to the supplier in writing without delay, however at the latest seven days
after the identification of the fault. If the customer fails to notify the supplier, the product is
considered approved despite the defect. Further liability for any direct or indirect damages
is not accepted.

If equipment-specific maintenance and servicing work defined by the supplier is to be
performed within the warranty period by the customer (maintenance) or by the supplier
(servicing) and these requirements are not carried out, claims for damages are rendered
void due to the failure to comply with the requirements.

Any further claims, in particular claims for consequential damages, cannot be made.

Consumables and damage caused by imcorrect handling, unsafe assembly or by incorrect
use are excluded from this provision.

The instruments of the manufacturer are of proven reliability in many applications and are
therefore often used in automatic control loops to provide the most economical possible
operation of the related process.

To avoid or limit consequential damage, it is therefore recommended to design the control
loop such that a malfunction in an instrument results in an automatic change over to the
backup control system, which is the most secure operating condition for the environment
and for the process
