Selection guide

Simultaneous thermal analysis combines TG with DTA or differential scanning calorimetry (DSC) to obtain thermogravimetric and differential thermal information simultaneously from the same sample in the same measurement.

Compared to TG and/or DSC tests alone, there are the following significant advantages:

1, through one measurement, you can obtain two kinds of information about mass change and thermal effect, which is not only convenient and time-saving, but also very advantageous for occasions where samples are expensive or difficult to obtain because only less samples are needed.

2, eliminate the weight, sample uniformity, heating rate consistency, atmosphere pressure and flow difference and other factors, TG and DTA/DSC curve better correspondence.

3, according to whether a thermal effect corresponds to the mass change, it helps to distinguish the physicochemical process corresponding to the thermal effect (such as distinguishing the melting peak, crystallization peak, phase transition peak and decomposition peak, oxidation peak, etc.).

4, real-time tracking of sample mass with temperature/time changes, in the calculation of enthalpy can be the current actual mass of the sample (rather than the original mass before measurement) as the basis, conducive to the accurate calculation of phase change heat, reaction heat, etc.

 

 

Product characteristics

1, the furnace body heating using noble metal nickel-chromium wire double row winding, reduce interference, more high temperature resistance.

2, tray sensor, made of precious metal nickel-chromium alloy seiko, with high temperature resistance, oxidation resistance, corrosion resistance and other advantages.

3, the power supply, the circulation heat dissipation part and the main machine are separated to reduce the impact of heat and vibration on the micro thermal balance.

4, the use of open cover structure, easy to operate. It is difficult to move up the furnace body to put samples, which is easy to cause damage to the sample rod.

5, the main engine adopts water constant temperature device to isolate the thermal influence of heating furnace body on the chassis and micro-thermal balance.

6, using imported 32bit ARM processor Cortex-M3 core, sampling speed, faster processing speed.

7. 24bit four-channel sampling AD collects DSC signal, TG signal and temperature T signal.

8, according to customer requirements to replace the furnace body.
