Question

Which of the following statements given below is false?

(a) TGA, DTA and DSC are measured using same instrument

(b) TGA and DTA can be carried out simultaneously.

(c) TGA, DTA and DSC are measured using different instruments.

(d) TMA is a recent name of Dilatometry.

This question was addressed to me in an international level competition.

My doubt is from Thermogravimetric Analysis in portion Thermal Analysis of Solid State Chemistry

Answer 1

Correct option is (c) TGA, DTA and DSC are measured using different instruments.

For explanation I would say: With modern automatic thermal analysis equipment it I possible to do TGA, DTA and DSC using the same instrument, with some models, TGA and DTA may be carried out simultaneously. However, the thermal analysis equipment is necessarily rather complicated and expensive in order that a wide variety of thermal events and properties may be studied.
