IKA C 1 Package 1/10 - Manual (Page 5)

5
We recommend that you send the C1 calorimeter system
to our factory for inspection, and if necessary, repair after
1000 tests or after one year or sooner depending on use.
For the purposes of these operating instructions a technical
expert is someone
1. who guarantees to conduct the tests properly on the
basis of his training, knowledge and experience gained
through practical work,
2. who is suffi ciently reliable,
3. who is not subject to any instructions in terms of the test
activity,
4.
who has suitable test equipment if necessary,
5. who can provide appropriate proof of the requirements
listed in 1.
National directives and laws must be observed for operating
pressure vessels!
Anyone operating a pressure vessel must keep it in a proper
condition, operate it properly, supervise it, carry out the necessary
maintenance and repair work immediately and implement the
safety measures required in the circumstances.
A pressure container must not be operated if it exhibits defects
that could endanger those working with it or third parties.
You can obtain a copy of the pressure vessel regulation from
Beuth Press.
The IKA® C1 calorimeter system is used for calorifi c value deter-
mination of solid and liquid substances.
This is done by placing a known quantity of a substance in a
decomposition vessel which is surrounded by a water jacket. The
sample is then combusted in an oxygen atmosphere . The calorific
value of the sample can then be calculated from the resulting
increase in temperature, the sample mass and the known thermal
capacity of the overall system.
The C1 calorimeter system is subject to the Pressure Vessel Directive
97/23/EC. Comply with the safety instructions accordingly
For adaptation to individual laboratory tasks, use original IKA®
consumables and accessories.

System properties
The IKA C 1 calorimeter is a combustion calorimeter for determi-
ning gross calorific values of liquid and solid non-explosive
substances. The samples were burned at an excess of oxygen
under pressure in a closed vessel. The resulting amount of
heat, measured in a previously calibrated system, allows the
determination of the calorific value of the sample after preliminary
various globally applied standards and regulations.
The necessary corrections after combustion in the calorimeter can
then, for example, about our CalWin C 6040 calorimeter software
(accessories), from the acid corrections up to the calorific value
according to DIN, ISO, ASTM, GB, and GOST standards typed,
corrected and calculated. By a transfer of the results to Excel can
quickly and easily adapt special or own calculations.
The worldwide unique patented IKA calorimeter C 1 operates on
the globally applied isoperibolic measurement procedure at 22 ° C
and 30 ° C. The temperature values are output every 12 seconds,
and the calculation of the temperature correction according to
standards Regnault Pfaundler.
Measurement times of the system:
- Sample preparation time: < 1 minute
- from the start of measurement until the start of the next: 12 minutes
- Pre-experimental period: Response of the system 3 minutes
- Hauptversuch: nach der Zündung der Probe 4 minutes
- Main experiment: after ignition of the sample: 5 minutes
To a supply of cooling water, the calorimeter can with a
conventional thermostat / cooler operate for example such as the
IKA KV 600 (accessory).
Do not use distilled or demineralized water (increased risk
of corrosion)!
Fill the cooler according to the cooler operating instructions.
Cooling water temperature settings on the thermostat / cooler:
- in mode of opretaion isoperibol 22 °C:
18 - 21 °C
- in mode of opretaion isoperibol 30 °C: 26 - 29 °C
Alternatively, the device can also be operated via an optionally
available heating C 1.20 (accessories) at a fixed water connection.
The accessories for connection to the water pipe or the
thermostat is contained in the corresponding delivery.
Requirements for the operation of the C 1 with the C 1.20 heating
on a water pipe:
- tap water: is recommended in drinking tap water quality. Mix in
(max. 1 ml for 4-5l of water) of the supplied water additive.
Thus, the durability of the water is improved.
- temperature range: 12 °C – 28 °C
(according to the water temperature, the measuring mode
22 ° C or 30 ° C must be selected).
- water pressure: max. 1 – 1,5 bar
(at higher or constant pressure, we recommend using the
C 25 water pressure regulating valve available as an
accessory)
- water consumption per measurement: about 4 liters
Automatic internal system checks enable the identification and
monitoring
• the presence of oxygen pressure
• the controlled stirrer speed
• the the availability of water in the system
• the input water temperature
• of inner vessel
• the correct shutter of the measuring cell with locking
• Ignition counter with memory function for the next due
maintenance
