3 Measuring Principle
10 C76IB003EN-N
3 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, the density value
of a binary mixture can be used to calculate its
composition with the aid of density/concentration
tables.
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.
Note that the accuracy of the concentration
measurement depends not only 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 – Overview
C76IB003EN-N 11
4 The Instrument – Overview
The density and concentration meters of the DMA M
series have been developed to combine highest
precision with easy operation and robust design.
Measurement is based on the oscillating U-tube
method that has been invented at a research
institute in 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.
• ThermoBalance™: 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 which is subsequently taken account of
in the calculation of the definitive density value.
• With DMA 5000 M, the precision for samples
with high viscosity and high density can be
increased by special adjustments with
standards of high viscosity and high density.
• The built-in atmospheric pressure sensor
enables correct air adjustment, as the air
density is dependent on the atmospheric
pressure.
Error detection
A major source of measuring errors with density
meters are gas bubbles in the measuring cell. This
issue is addressed by Anton Paar with two new
features:
• FillingCheck™: The instrument automatically
detects inhomogeneities and gas bubbles in the
whole measuring cell by an advanced analysis
of its oscillation pattern. Where necessary, a
warning message is generated in real time for
every single measurement.
• U-View™: Real-time images by a camera with
zoom function enable you to visually inspect the
measuring cell.
User interface
The touch screen user interface facilitates easy and
intuitive operation in routine applications as well as
in demanding 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.
• Density values are automatically converted into
concentration values for a large number of
factory-programmed substances. You can add
further substances as required by yourself.
• Optionally operate DMA 4100/4500/5000 M via
external keyboard, mouse, or bar code reader.
• Optionally connect an external monitor or touch
screen (VGA interface).
Compact and robust design
The instruments of the DMA M series keep up the
tradition of the legendary previous DMA generations:
• Compact design
• Sealed housing
• Robust housing materials: coated aluminum
(top and sides), aluminum (base and back), and
polystyrene/butadiene (front)

For the installation of an Xsample filling module, see
the respective instruction manual.
7.1 The Right Place
DMA 4100/4500/5000 M is designed for operation
under typical laboratory bench top conditions.
To guarantee temperature stability, do not place the
instrument:
• near a heat source
• in a drafty place (e.g. near an air conditioner)
• on a vibrating surface or close to vibrating
equipment
• in direct sunlight
7.2 Mounting the Injection Adapters
1. Take two injection adapters Luer with screws
from the accessory kit.
2. Pull out the black plastic transport plugs from
the tips of the injection adapters.
TIP: Keep the plastic transport plugs for later use.
They can be used as an injection adapter tool to
widen the tips of the adapters in case of leaks.
Fig. 7-1: Mounting the injection adapters Luer
3. Carefully insert the injection adapters into the
openings of the adapter holding plate on the
right side of the instrument, see Fig. 7-1.
4. Push both adapters towards the holding plate
with moderate force.
5. Insert the screws through the bore holes of the
adapters and screw them cautiously into the
adapter holding plate until some resistance
against further turning can be felt.
WARNING
Using hazardous or flammable chemicals as
samples or cleaning liquids could lead to
damage of the instrument and cause serious
injuries unless special precautions are taken.
• Observe the safety instructions in the section
"Special precautions for flammable chemicals"
in section 2.
NOTICE
• Ensure that the power plug and the power
switch are always easily accessible so that the
instrument can be easily disconnected from
the mains supply at any time.
• A strong built-in cooling fan dissipates heat
through the bottom and the rear of
DMA 4100/4500/5000 M. Ensure that the air
flow is not blocked, and provide for a minimum
distance of 10 cm (4 in) to walls behind and
beside the instrument.
• High humidity or a measuring temperature that
is significantly below the ambient temperature
may lead to condensation within the
measuring cell. Install a drying cartridge to
avoid condensation, see appendix C.1.
CAUTION
If the screw for fastening the adapter is
overtightened, the density measuring cell may
be damaged. Harmful liquids leaking from the
instrument may cause injuries.
• Tighten the screw until some resistance
against further turning can be felt, and then
stop to tighten the screw.
The gap left between the holding plate and the
adapter, where the thread of the screw can be
seen, is approx. 3–8 mm (approx.
0.12–0.31 in).
