You could be seriously injured by expelled parts.
− Never open the pressure cylinder when the system is under pressure.
Safety Information 7Thermal Analysis Excellence
CAUTION
Risk of personnel injury or damage to the instrument due to operation at high pressure.
1 Use the pressure measuring cell only for experiments for which it has been
manufactured in regard to maximum working pressure, corrosion resistance and maximum temperature.
2 Make sure that the maximum working pressure of 10 MPa is not exceeded. The built-
in rupture disk responds at a pressure of 12.4 to 13.8 MPa.
3 When releasing flammable gases, make sure that the gas is vented according to the
laboratory safety regulations. Connect gas outlet and rupture disc to lines that lead off the gas for proper disposal. Especially take measures to prevent the gas from flowing into the instrument’s housing.
4 Never use corrosive gases for the pressure buildup or purging.
With time, corrosive gases attack and weaken the materials of the parts under pressure. Material weakness can lead to an explosion or to leaks in the pressurized measuring cell.
2.2.2.2 Measures for your protection
WARNING
Risk of electrical shock.
An electrical shock can be lethal. 1 Only use the original power supply cable provided with your instrument and plug it
into a grounded outlet. 2 Never open the instrument housing. 3 The power plug must be easily accessible.
WARNING
Risk of explosion if the instrument is used in an explosive atmosphere.
The housing of the instrument is not gas tight. An explosion caused by a spark can be lethal.
− Never work in an environment subject to explosion hazards.
CAUTION
Risk of surfaces on the instrument heating up unduly after switching off the cooling device prematurely.
You can burn yourself on hot surfaces on the measuring cell and in its surroundings. Hot surfaces on the instrument can cause a fire.
− Never switch off the instrument or the cooling device when the temperature in the
furnace is above 100 °C.
CAUTION
Risk of damage from flammable samples.
Using flammable samples can cause damage to the instrument and in its vicinity.
− Take suitable measures to minimize any risk. See chapter "Operation" for more infor-
mation.
Safety Information8 Thermal Analysis Excellence
CAUTION
Risk of explosion or fire due to explosive or flammable gas mixtures.
Explosion or fire from gas mixtures produced in the sample chamber can seriously injure you.
1 Never use gases which may result in an explosive or a flammable gas mixture. 2 Never use explosive or flammable gases or gas mixtures to purge the measuring cell.
CAUTION
Risk of toxic or corrosive gases from samples that react or decompose.
You can be poisoned if you inhale toxic gases. Corrosive gases can damage the measuring cell.
1 Place the instrument in a fume hood if you measure substances which form toxic
gases.
2 Purge the furnace and sample chamber with an inert gas after experiments in which
toxic or corrosive gases may have been produced. Do not use toxic or corrosive or gas mixtures to purge the measuring cell.
CAUTION
Risk of injury due to heavy load.
You can injure yourself by carrying the instrument alone.
− Never try to carry the instrument alone. At least two people are needed to carry the instrument.
CAUTION
Risk of hot surfaces.
You can burn yourself by touching parts of the measuring cell, furnace or the crucibles. 1 Always ensure cooling water flow (20 to 30 °C). The pressure cylinder and cover
would otherwise become so hot that you could burn yourself.
2 Allow the measuring cell to cool down to room temperature before performing any task
on the furnace.
3 Never place your fingers on or inside the furnace after an experiment. 4 Use tweezers to remove the furnace lid and crucibles.
Safety Information 9Thermal Analysis Excellence
2.2.2.3 Measures for operational safety
CAUTION
Risk of false operation.
False operation can cause damage to or failure of the instrument. 1 Use only gas sources with a pressure regulator and a check valve. Never set the
pressure at the regulator higher than 10 MPa (maximum operating pressure). The gas
source may become contaminated in the absence of a check valve. 2 Never remove the pressure cylinder for measurements at ambient pressure. 3 Always set the pressure buildup using with the INLET valve. 4 Make sure that the CONTROL IN needle valve (for fine regulation) is not closed tightly
otherwise the needle valve could be damaged. 5 When using chemicals and solvents, comply with the instructions of the manufacturer
and the general lab safety rules. 6 The cooling device should also be on when the instrument is switched on. 7 The cooling fluid should not be colder than 15 ºC, otherwise condensation could
develop. 8 Use the instrument only indoors in a well-ventilated area, at altitudes of less than
3000m above sea level. 9 Avoid the following environmental influences:
- Powerful vibrations
- Direct sunlight
- Atmospheric humidity greater than 80% (non-condensing)
- Corrosive gas atmosphere
- Temperatures below 10 °C and above 31 °C
- Powerful electric or magnetic fields
10 Have the instrument serviced only by METTLER TOLEDO Service.
Note
The above list is not exhaustive; other items and precautions may have to be considered.
Safety Information10 Thermal Analysis Excellence
2.2.2.4 Safety notes related to operation with explosive or flammable gases
CAUTION
Risk of explosion or fire if explosive or flammable gases are used.
You can be injured and the instrument can suffer damaged.
− If an application requires the use of explosive or flammable gases, you must be aware of the risks and take appropriate safety precautions.
The HP DSC module is not designed for the use of explosive and flammable gases and the system is not explosion-proof. METTLERTOLEDO excludes liability for all personal injury or damage resulting from using explosive or flammable gases on the instrument.
See [Precautions to minimize risks when using explosive or flammable gases}10].
2.2.2.5 Precautions to minimize risks when using explosive or flammable gases
− Work in a room especially designed for working with explosive gases (alarm system, wall thickness and so on).
− Put the instrument behind safety walls or operate it from a safe place. Make sure that no other persons are in danger.
− Consider the risk that the flammable gas can accumulate in the instrument housing. If needed, purge the housing with inert gases to avoid dangerous explosive concentrations.
− To release flammable gases, make sure that the gas is vented according to the laboratory safety regulations. Especially take measures that the gas does not flow into the instrument housing.
− Check the tubing system for leaks before working with the flammable gas. For example use helium and a corresponding gas leak detector. Check the measuring cell as well.
− Take measures to vent explosive and hot gas in case the rupture disk bursts. The instrument is fitted with a rupture disk as a protection against overpressure. This disk may burst during the measurement and release the explosive and hot gas.
− Before loading the cell with the flammable gas, fully replace the air by an inert gas so that explosive gas or oxygen concentration is avoided. Pressurize to 1 MPa with nitrogen and release the gas at least three times or purge long enough with the inert gas.
− Never open the furnace when it is hot, wait until the furnace temperature is below 30 °C.
Note
The above list is not exhaustive; other items and precautions may have to be considered.
Avoiding explosive mixtures
Loading and unloading the samples requires opening the pressure cylinder so that the surrounding ambient gas, usually air, mixes with the furnace atmosphere: An explosive mixture can be created which will be ignited by hot surfaces or sparks.
− Put the measuring cell in a glove box with an inert atmosphere to reduce the risk of having oxygen in the measuring cell
- or ­Fill the furnace with nitrogen (or other inert gas) before opening the cell (pressurize to 1 MPa with nitrogen and release the gas at least three times or purge long enough with the inert gas).
Risk of damaging the instrument
The flammable gas may chemically or physically alter some materials of the measuring cell, furnace, crucible and the sample itself. This could damage the sensor or other parts of the instrument by forming alloys or in other ways.
Safety Information 11Thermal Analysis Excellence
2.2.2.6 Special safety notes on using hydrogen
If hydrogen has to be used to create a reducing atmosphere or to minimize the oxygen concentration, a non-explosive mixture of ≤4% hydrogen in an inert gas is the preferred solution. The explosion limits of hydrogen in air cover a very broad range from 4% to 77%. (The explosion limits of hydrogen and other gases are indicated in the table below.)
The thermal conductivity of hydrogen is much higher than that of nitrogen. Hence, the surroundings of the furnace may get much hotter than usual and the furnace may not reach the highest end temperatures
2.2.2.7 Explosive limits
Explosive limits, also called flammable or flammability limits, give the proportion of combustible gases in a mixture, between which limits this mixture is flammable. Gas mixtures consisting of combustible, oxidizing, and inert gases are only flammable under certain conditions. The lower flammable limit (LFL) (lower explosive limit) describes the leanest mixture that is still flammable, i.e. the mixture with the smallest fraction of combustible gas, while the upper flammable limit (UFL) (upper explosive limit) gives the richest flammable mixture. Increasing the fraction of inert gases in a mixture raises the LFL and decreases UFL.
These limits depend on temperature and pressure and are given here for initial conditions of 0.1 MPa and 20°C. (Source: MERCK catalog 1990/91).

5 Operation
This section describes the operation of the HP DSC module for the configuration "Performing an experiment without a flow meter, flow controller and pressure controller". Additional scenarios are described in the Reference Manual, which can be downloaded here: http://swupdateamc.mt.com/
5.1 Workflow for experiments
We recommend the following workflow for conducting experiments.
1
Choose the measurement technique: DSC
2
Create a temperature program.
3
Choose the crucible type.
4
Prepare the sample and the crucible.
5
Choose the atmosphere (gas, pressure).
6
Perform the experiment.
7
Remove and examine the sample after the measurement.
8
Evaluate the measurement curves.
5.2 Preparing the HP DSC module for experiments
5.2.1 Hints before you start an experiment
CAUTION
Risk of uncontrolled pressure release.
You could be seriously injured by expelled parts.
− Never open the pressure cylinder when the system is under pressure.
Apply this procedure only if you are not working according to a specified norm. The instructions may differ significantly.
• The closed measuring cell needs a relatively long time to cool down to room temperature after a
measurement. The cooling proceeds faster if the cell is under pressure.
• If you start your measurements at a relatively high starting temperature (the measuring cell is heated up
rapidly), we advise waiting for a constant pressure display before confirming Insert sample on the module display.
• If you need a more accurate pressure reading for your measurements or if you use the same gas for
pressure buildup and purging, you can attach the PC 10 pressure and mass flow controller. For more information, see the chapter "Installation and Putting into Operation".
Pure gas atmosphere
If you need a pure gas atmosphere, repeat the following procedure each time:
− Fill (up to approx. 2 MPa) and empty (close INLET valve, open OUTLET valve) the pressure cell three times with gas, before you fill the cell with gas for the measurement.
Protection against strong exothermal reactions
To protect the DSC sensor from breaking during a measurement in which a strong exothermal reaction could occur, you can apply the following procedure. This will protect the DSC sensor from large temperature gradients resulting from sudden heat release and lessen mechanical stress or shock.
− Insert a sensor protection disk between the DSC sensor and the crucible on both the sample and reference sides. See "Accessories and Spare Parts" in the Reference Manual.
Operation28 Thermal Analysis Excellence
Protection against inflammable substances
− Take the following measures to protect the instrument from being damaged during measurements in which flammable substances are used as samples:
− Insert a sensor protection disk between the DSC sensor and the crucible as explained above.
− Use only small quantities of the substances.
− Use a suitable crucible, for example a high pressure crucible, to prevent any damage.
− Dilute the flammable substance with an inert substance such as aluminum oxide.
5.2.2 Crucibles – without lid or with perforated lid
Depending on the application, you can work with a crucible without a lid, for example, when measuring oils to determine their oxidative stability.
For enthalpy determinations, you should perforate the crucible lid once using the needle from the crucible set.
For determinations of boiling temperatures, perforate the crucible lid, on a hard surface with a compass point (hole diameter: approximately 50µm) or use the perforated lids from METTLERTOLEDO.
Attention
Don’t use a hermetically sealed crucible: It will collapse under pressure greater than 1 MPa.
5.2.3 Performing a leak test
Before you perform the first measurement under pressure, you should test the measuring cell for leaks with an inert gas such as nitrogen.
Attention
Always use a gas source (bottle or line) that has a check valve and a reducing valve. 1 Close the valves CONTROL IN, OUTLET, INLET and AUX. 2 Attach the gas source to INLET. 3 Set the pressure of the gas source with the reducing valve to 10 MPa and open the gas source. 4 Open INLET valve: The pressure should increase at a maximum rate of 0.1MPa/s 5 Build up a pressure of 10MPa. 6 Close INLET valve and observe the pressure gauge and wait for 30 minutes to allow the pressure to
stabilize.
7 After another 30 minutes check the pressure again: The pressure drop in the measuring cell should be
less than 0.2 MPa. If this is not the case, several [malfunctions}39] can be the cause.
8 Open the OUTLET valve after the test to let the gas flows out.
5.3 Performing an experiment
5.3.1 Loading the sample crucible into the measuring cell
CAUTION
Risk of uncontrolled pressure release.
You could be seriously injured by expelled parts.
− Never open the pressure cylinder when the system is under pressure.
CAUTION
Risk of hot surfaces.
Touching hot surfaces or samples can cause burns. 1 Never touch the furnace or furnace lid. 2 Let the hot surfaces cool to room temperature before handling. 3 Remove samples wearing gloves or with tweezers.
Operation 29Thermal Analysis Excellence
Attention
The valves are fragile. Close them only finger-tight. 1 Open the pressure cell by unscrewing the four nuts on the pressure cylinder cover and lifting it off
(Attention: Heavy).
2 Remove the alumina wool mat. 3 Remove the furnace lid with tweezers. 4 Place the sample crucible carefully on the left side of the DSC sensor and place an empty reference
crucible on the right.
5 Replace the furnace lid using tweezers. Make sure that the lid is in the correct position and the tooth on
the furnace top fits into the notch in the side of the lid. You could otherwise jam it.
6 Place the alumina wool mat in the pressure cylinder on top of the furnace and press down. Before
mounting the pressure cylinder cover make sure that its O-ring is free of alumina wool fibers. 7 Mount the pressure cylinder cover and tighten the four nuts by hand. This is sufficient to seal the system. 8 Set the flow rate of the cooling water to approximately 30 L/h. 9 On the HP DSC, close the CONTROL IN, OUTLET, INLET and AUX valves. 10 Open the gas inlet for the pressure buildup. 11 Open the INLET valve slowly and watch the level on the pressure gauge. 12 Close the INLET valve when the pressure is reached.
ð The sample is loaded. See "[Starting the experiment}30]" to continue with the experiment.
Pressure not controlled
When you perform isothermal measurements, you can set the required pressure at the desired temperature. The pressure does not change during the measurement.
In dynamic measurements, the pressure increases with the temperature in a manner which depends on the cooling of the pressure cylinder.
If you measure over a small temperature range, the pressure change is correspondingly small. If you require accurate pressure data, we advise plotting a pressure-temperature curve. See example below.

5.3.2 Starting the experiment
§ The sample and reference crucibles are inserted. 1 Start an experiment on the module. Wait until the measuring cell has reached the insertion temperature.
2 Click OK in the Module Control Window.
ð The measurement starts. At the end of the measurement the "Remove sample" request appears in
the Module Control Window.
Attention
– If you start your measurements at a relatively high start temperature, in other words the measuring
cell heats up rapidly, we advise waiting for a constant pressure display before starting the
experiment (confirm "Insert sample" after getting a constant pressure).
– Define a suitable temperature for sample removal (Example: 40 °C)
3 To remove the sample after the experiment has finished, see [Removing the sample and switching off
the instrument}31].
Operation 31Thermal Analysis Excellence
5.3.3 Removing the sample and switching off the instrument
CAUTION
Risk of uncontrolled pressure release.
You could be seriously injured by expelled parts.
− Never open the pressure cylinder when the system is under pressure.
§ The module is in the "Wait for sample removal" state.
1 Open the quick-vent valve slowly to release the pressure. 2 When the pressure gauge shows zero (0) pressure, open the valve fully to be certain that the cell is
definitely at atmospheric pressure.
Attention
Do not unscrew the nuts until the measuring cell is at atmospheric pressure. Unscrew all 4 nuts by one
turn and then remove them individually. 3 Unscrew the nuts.
4 Remove the pressure cylinder cover (Attention: Heavy), the alumina wool mat and the furnace lid.
5 Remove the sample using tweezers.
Attention
– If you are using an alumina crucible, allow it to cool down first before placing it on a cold surface. The
crucible might otherwise crack due to too rapid cooling. In general, do not place the crucibles on a cold
surface or on the instrument housing.
– For temperatures above 400°C, the furnace lid could become fixated while cooling down. To loosen
it, you can heat the cell to 600°C and lift it off while it is still hot. Be careful not to burn yourself.
