2 Safety Instructions
C76IB003EN-E 11
• The installation procedure shall only be carried out by authorized personnel
who are familiar with the installation instructions.
• Do not use any accessories or wearing parts other than those supplied or
approved by Anton Paar GmbH.
• Make sure all operators are trained to use the instrument safely and correctly
before starting any applicable operations.
• In case of damage or malfunction, do not continue operating DMA 4100/
4500/5000 M. Do not operate the instrument under conditions which could
result in damage to goods and/or injuries and loss of life.
• If liquid was spilled over the instrument, disconnect the instrument from the
mains. Clean and dry the housing of the instrument. If you have a suspicion
that liquid got into the instrument, have the instrument cleaned and checked
for electrical safety by a service technician.
• Ensure that spilled liquids cannot get into plug connections or venting slots of
electrical equipment.
Moving the instrument
• Make sure that all hoses and the measuring cell are empty before you move
or lift DMA 4100/4500/5000 M.
• To move or lift DMA 4100/4500/5000 M, place one hand at the back and grip
the ledge at the top. Place the other hand at the front, under the display.
There is a hollow for your fingers.
• When carrying the system, keep it close to your body.
Handling of chemicals
• Observe all safety regulations regarding the handling of the samples,
cleaning, rinsing and waste liquids (e.g. use of safety glasses, gloves,
respiratory protection, exhaustion, etc.).
• Check the chemical resistance of all materials (see Appendix A.2) which
come into contact with the sample or cleaning liquid before starting the
measurement.
• Make sure that different liquids (samples and cleaning liquids) or gases that
come into contact with each other are chemically compatible. They should
not react exothermally or produce any solid particles that might stick to the
inner wall of the measuring cell.
• Prior to starting a measurement or cleaning procedure, make sure that all
parts that come into contact with fluids, especially the measuring cell, the
injection adapters, hoses and waste container, are properly connected and in
good condition.

2 Safety Instructions
12 C76IB003EN-E

3 The Measuring Principle
C76IB003EN-E 13
3 The Measuring Principle
Definition of density and specific gravity
The density ρof a sample is defined as mass divided by volume:
The specific gravity SG is calculated by dividing the density of a sample by the
density of pure water at 20 °C:
Density and Specific Gravity values are highly temperature-dependent.
The oscillating U-tube method
The sample is introduced into a U-shaped borosilicate glass tube that is being
excited to vibrate at its characteristic frequency. The characteristic frequency
changes depending on the density of the sample. Through a precise
determination of the characteristic frequency and a mathematical conversion, the
density of the sample can be measured.
The density is calculated from the quotient of the period of oscillations of the U-
tube and the reference oscillator:
Concentration measurement
In binary mixtures, the density of the mixture is a function of its composition. Thus,
by using density/concentration tables, the density value of a binary mixture can
be used to calculate its composition. This is also possible with so-called quasi
binary mixtures. These are mixtures containing two major components and some
additional components which are present in very small concentrations compared
to the two main components. Many decarbonated soft drinks, for example, can be
considered to be quasi binary solutions of sugar in water because the
concentration of flavors and acids are very small compared to sugar and water.
Thus, the sugar concentration can be measured with a density meter.

4 The Instrument - An Overview
14 C76IB003EN-E
Note that the accuracy of the concentration measurement depends on the
accuracy of the instrument, but also on the slope of the density/concentration
correlation. This means, for example, that a density measurement with an
accuracy of ±0.00001 g/cm3will be converted into an ethanol value with a
significantly smaller accuracy of ±0.025 % w/w. The accuracy of some typical
concentration measurements is given in Appendix A.1.
4 The Instrument - An Overview
The DMA M series instruments are density and concentration meters that were
developed to combine highest precision with easy operation and robust design.
The measurement is based on the oscillating U-tube method which was invented
by Dr. Hans Stabinger and Dr. Hans Leopold at the Joanneum Research Institute
(Graz, Austria) and first introduced onto the market by Anton Paar in 1967.
Features and Benefits
Accuracy
Your DMA M series instrument is equipped with the world’s most advanced digital
density measurement technology:
• The period of oscillation of the U-tube is measured by optical pickups.
• Two integrated Pt 100 platinum thermometers together with Peltier elements
provide an extremely precise thermostatting of the sample.
• ThermoBalanceTM: An additional reference oscillator provides long-term
stability and enables precise measurements over the whole temperature
range of the instrument with only one adjustment at 20 °C.
• Viscosity-related errors are automatically corrected over the full viscosity
range by measuring the damping effect of the viscous sample followed by a
mathematical correction of the density value.
• In the DMA 5000 M, special adjustments with standards of high viscosity and
high density lead to an enhanced precision for samples with high viscosity
and high density.
Error detection
A major source of measuring errors when using density meters are gas bubbles
in the measuring cell. This issue was addressed by Anton Paar with two new
features:

4 The Instrument - An Overview
C76IB003EN-E 15
• FillingCheckTM: The instrument automatically detects inhomogeneities and
gas bubbles in the whole measuring cell by an advanced analysis of its
oscillation pattern and generates a warning message in real time for any
single measurement.
•U-View
TM: You can visually inspect the measuring cell using a real-time
camera with zoom function (DMA 4500/5000 M).
User interface
The touch screen user interface supports easy and intuitive operation in routine
applications as well as in sophisticated scientific research work:
• For the most common applications, 10 measuring methods are predefined.
Just select the method fitting your application or create your own methods.
• The density values are automatically converted into concentration values for
a large number of factory-programmed substances. You can also program
special substances as required.
• Under harsh industrial conditions, operate the DMA M with the set of robust
softkeys instead of the touch screen.
• You can operate the DMA M via external keyboard, computer mouse or bar
code reader.
• You can connect an external terminal or touch screen (VGA interface).
Data management and safety
The DMA M series offers up-to-date data management and safety features to
make your work easier and help you comply with your quality management
regulations:
• Print out reports.
• Export your data in the format of your choice (MS Excel, text or PDF).
• Choose between the interfaces: 4 x USB, Ethernet, RS-232, 2 x S-BUS and
CAN BUS.
• Use the powerful audit trail function with tamper-proof data export
(checksum).
• Rely on full compliance with GLP/GMP and 21 CFR part 11.

5 Checking the Supplied Parts
16 C76IB003EN-E
Compact and robust design
The tradition of the legendary previous DMA generations is continued in the
M series:
• Compact design
• Sealed housing
• Robust housing materials: coated aluminum (top and sides), aluminum
(base and back) and Polystyrene/Butadiene (front).
5 Checking the Supplied Parts
DMA 4100/4500/5000 M was tested and packed carefully before shipment.
However, damage may occur during transport.
1. Keep the packaging material (box, foam piece, transport protection) for
possible returns and further questions from the transport and insurance
company.
2. Check the delivery for completion by comparing the supplied parts to those
noted in Table 5.1.
3. If a part is missing, contact your Anton Paar representative.
4. If a part is damaged, contact the transport company and your Anton Paar
representative.
