Heat flux DSC detects the difference in heat flow which is supplied to the

sample and reference uniformly. The sample and reference are heated or

cooled by heat flow from the heat sink through the temperature sensors.

Since the heat sink has a much larger total heat capacity in comparison

to the sample and reference, the heat flow in or out of the sample is

proportional to temperature difference between the sample and reference

holders. This heat flow is quantitative and displayed as a y-axis signal in

mW.

STA Simultaneous Thermal AnalyzerPioneer of digital dual beam tg/dtatechnology

Hitachi is the pioneer in Thermal Analysis providing simultaneous instruments, combining the high flexibility of the differential temperature analysis (DTA and/or DSC) with the proven capabilities of the thermo gravimetric Analyzer (TGA) with dual beam TG/DTA/DSC technology. The TA 7000 STA series feature a proven dual beam design, which is highly resistant to environmental influences such as temperature, table and building fluctuations or vibrations. This guarantees a drift free baseline without chimney and convection effects.The newly developed Beam Expansion Correction wizard performs automatically the full calibration of the system. This drastically improves the TG/DSC performance without service interaction and furnace adjustment.TA 7000 series STA systems allow you simultaneous TG/DTA/DSC measurements providing information about decomposition temperature, compositional analysis, flammability studies, oxidative stabilities and transition temperatures. The digital dual beam design ensures that the sample is exposed in the desired temperature and gas environment to obtain highly reliable data.

IDEAL ENVIRONMENT CONTROL TECHNOLOGYIn the horizontal dual beam balance the gas low is perpendicular to weight measurement. This means

that there is no interaction of reaction gas low on the mass signal, even at low rates up to 1000

ml/min. This allows the user to measure even minor weight losses at very low mass samples in a

controlled atmosphere without any baseline correction.

OUTSTANDING SENSITIVITY AND ACCURACYThe Hitachi digital dual beam technology is the only one which guarantees accurate compensation of

Thermal Expansion effects of the balance beams. The “Fuzzy Logic” temperature control and the low

mass furnace together allow precise temperature control, prevents overshoots and therefore enables

the Controlled Rate Thermal Analysis (also called Sample Controlled Thermal Analysis).

ONE TOUCH DESIGNED DUAL BALANCE BEAM The patented one touch type dual balance-beam design allows users to exchan-ge the beam by themselves easily. Light weight balance beam ensures STA 7000 series with the highest sensitivitysitivity and stability.

A separate purge port for aggressive reaction gases is available. By the use of this optional gas inlet port corrosive reaction gases can be used without a damage of the balance mechanism.

TA 7000 series STA software provides direct calibration functions by using high purity metal standards. The thermocouple is in direct contact with the sample platform which ensures highly accurate temperature readings. With the multiple points pre-calibration, the most accurate temperature control over a wide temperature range can be achieved. The calibration of the temperature control works as a “just press a key” function can be performed and saved under various experiment conditions and therefore sa--ves maintenance costs.

Controlled Rate Thermal Analysis (CRTA, also called Sample Controlled Thermal Analysis SCTA) is equipped as a standard. This technique allows the control of the heating rate as a function of the weight loss. This method allows the separation of close weight losses without reducing the heating rate to 1 or 2°C/min. All settings are user selectable and the control of the heating rate is totally user unattended.

OUTSTANDING SENSITIVITYThe precise and accurate measurement of the coefficient of thermal

expansion depends on factors like temperature calibration,

resolution and sensitivity. With the 20 point temperature calibration,

the resolution in the nm range and the unsurpassed temperature

accuracy the TMA from Hitachi High-Tech Science fulfills all those

needs.

MELTING PROTECTION FUNCTIONIn order to protect the sample holder and the probes, the TMA is equipped with the function to shut down the measurement is the user defined displacement ranges are exceeded.

HIGH VOLUME TGThe TMA can be used as a high mass,

high volume TGA with a max. sample mass of 600 g and a

maximum volume of 2 ml (USA Patent 5826983).

AUTOMATIC SAMPLE LENGTH MEASUREMENTWhen the measurement starts, the sample length is automatically

measured by the instrument under defined load and temperature

conditions. This function is easy to use, eliminates human errors in

handling micrometers and ensures highest accuracy.

Theory of OperationThe key components of the instrument are the force generator,high sensitivity LVDT displacement detector, step motor and thestress strain control. The vertical design guarantees direct contact between force generator and the sample via the probe and very low compliance of the system, while the LVDT precisely measures the position of the magnet in the center of the detector. The step motor records the position of the sample cylinder while the LVDT measures the position of the probe. The difference of both signals reflects the sample dimensions. This principle allows the measurement of the sample dimensions in the instrument before the run is started.

SYNTHETIC OSCILLATION MODEIn this mode multiples of the basic frequency are overlaid

and the results calculated using the Fourier

transformation. The advantages are evident. Samples can

be measured at up to five frequencies at high data

collecting rates with higher heating rates. This technique

allows the frequency multiplexing even on samples which

undergo drastic softening in a very narrow temperature

range.

FOURIER TRANSFORM (FT)The TA 7000 DMA uses the Fourier Transform approach

to analyze the strain signal with the highest possible- re

solution. This allows precise phase angle measurements

at low levels with very small deformation amplitudes.

This greatly enhances the measurement range for stiff

and very soft samples all with one instrument.

The relevant signal for viscoelasticity is calculated and derived from the phase shift between stress and strain. The lenght deformation caused by creep and/or thermal expansion of the sample is compensated by the thermal expansion correction function.

THERMAL EXPANSION CORRECTION FUNCTIONDuring measurement in the wide temperature range (-150 to 600°C) samples undergo thermal expansion, shrinkage and creep. The highly

accurate step motor automatically compensates the dimensional

changes and makes sure the applied force is always the desired one,

pre-tension is correct and the LVDT stays in its measurement range.

This patented technique (USA Patents 4967601, 5046367, 5154085,

5182950) guarantees highly accurate and reliable data.

WIDE MEASUREMENT RANGEAll deformation modes are available including dual and single cantilever,

bending, shear and film shear, three

point bending for stiff samples, and

tension for thin films and single fibers

with diameters down to a couple of

µm. The sophisticated auto tension

mode reduces the pretension during

softening.

ADVANCED DMA

SOFTWAREThe advanced software package includes geometry depending

subtraction, generation of master curves

and calculation of activation energy as

standard. The unique Test Mode

function makes it easy for the operator

to determine the best suited sample

geometry and to choose the best

deformation mode for his sample.

MULTIBLE DEFORMATION

MODESAs standard the DMA 7100 comes with

the 20 mm tension head. To be able to measure samples with different

characteristics a variety of optional heads are available. This ranges from

dual and single cantilever with different active lengths, 3 point bending,

shear and film shear, to tension and compression. This allows

characterization of all sample shapes from single fibers to stiff bulk

samples.

PDC SPECIFICATION

As innovative company Hitachi High-Tech has developed the first specially designed PDC system for the measurement and analysis of photochemical reactions. Following the market needs the PDC 7 was developed. This is a specially designed attachment to the DSC 7000 series systems. It combines the advantages of a high sensitive DSC, with the needed high resolution requirements of the measurement of the fast photocuring reactions with the technology of the light transfer via optical fibers and therefore the possibility of having the high irradiation intensities of 500

2mWcm . It is very simple to change the intensity and the wavelength. As known the atmosphere is controlled in the usual way in the DSC reaction chamber. The DSC can be used in the normal way for standard applications.

PRINCIPLE OF CONTROLLED RATE THERMAL ANALYSIS

1. AUTO STEPWISE FOR BETTER STEP SEPARATION STATING THRESHOLD > EXIT THRESHOLD

2. CONSTANT REACTION RATESTATING THRESHOLD = EXIT THRESHOLD

CRTA is a measurement method which automatically controls the heating rate according to the signal chan-ge of thermal analysis module. The parameters can be chosen by the operator.

Once the reaction rate of the sample reaches the starting threshold set by the operator, the heating rate automatically changes to isothermal conditions. Heating continues when the reaction rate reaches the exit threshold.

With this measurement mode, the heating rate is controlled in a way that the signal change is linear. The speed is user selectable. The result is the necessary temperature proile to acheive this linear reaction rate.

HEATING RATE CONVERSION SOFTWAREThe Highway software improves quantitative compositional analysis through sophisticated

mathematical algorithms (Peak/curve separation and Arrhenius first order kinetics) to simulate the

measurement under different scan rate and to better separate the overlapping measured curve such as

weight loss events. Samples can be analyzed at normal DSC and TGA heating rates, i.e. 20°C, and with

the use of Highway software, the DSC and TGA data can be transposed to very slow (0.001°C/min)

heating rates and very fast (100,000°C/min) heating rates. This patented technology greatly improves

the prediction of reactions un der different heating rates and the separation of overlapping weight loss

events. (USA patent: 6210035, 6146012)

TYPICAL APPLICATIONSReduced measurement time for quality control. Data can be obtained with fast heating rates to save

measurement time. The quality and resolution of the results is as good as if measured with low rates.

RESEARCH AND DEVELOPMENT APPLICATIONSHeating Rate Conversion Software has been proven to provide an accurate prediction of the transitions

which would otherwisehave had to be measured with low heating rates. It is also useful for:

Ÿ Calculation of the activation energy value by the comparison of the calculated and measured data.

Ÿ Separation of TG and DSC peaks (by different activation reaction energies)

Ÿ Proven to get results, one can’t obtain by other technologies
