TG-DTA-MS coupled technique

MS—MS is a highly sensitive technique for identifying unknown compounds. When bombarded with electrons, all substances ionize and fragment in a unique manner. The mass spectrum, which records the masses and relative abundances of the ion fragments, gives a fingerprint for each compound. MS, using quadrupole mass spectrometers, is the most commonly used EGA technique.
