thermogravimetry Physical Chem.|θɜːməʊgrəˈvɪmɪtrɪ|
[f. thermo- + gravimetry.]
The technique of chemically analysing substances by measuring changes in weight as a function of increasing temperature.
1951Chem. Abstr. XLV. 2274 (heading) Thermogravimetry and automatic gravimetry. 1953Nature 22 Aug. 365/1 The advantage of the differential thermogravimetry over differential thermal analysis is that it is quantitative. 1975H. L. Friedman in I. M. Kolthoff et al. Treat. Analytical Chem. III. iii. d–1. 401 In thermogravimetry (TG), one generally records the weight of a sample continually as it is heated through a preselected rate of temperature rise.
Hence ˌthermograviˈmetric a.
1953C. Duval Inorg. Thermogravimetric Analysis i. 3 The investigations of Honda.., and the construction by Chevenard of automatic recording instruments, have all combined to give birth to a new science which we may perhaps call thermogravimetric analysis. 1972Nature 15 Dec. 418/1 According to our thermogravimetric analyses compounds (III)–(V) contain one molecule of lattice water per formula unit. 1977Proc. R. Soc. Med. LXX. 518/2 If the stone has been passed or removed it should be analysed. This may be by wet chemistry..or by physical methods such as infra-red spectroscopy..X-ray crystallography..or thermogravimetric analysis. |
