熱天秤、始動。

Today, we started operating a device called TG-DTA (ThermoGravimetric-Differential Theimal Analysis). This device measures the change in weight of a sample placed on a balance and the exotherm/endotherm at the same time to see how the sample has changed (e.g., melted, volatilized, turned into glass).

The device itself had been around since 1998 and was older than the 4th year student. Although it had been a while since the device was started up, it seemed to be able to make measurements without any major problems.

本日から TG-DTA（ThermoGravimetric-Differential Theimal Analysis, 熱重量示差熱分析）と呼ばれる装置の運用を開始しました。この装置は天秤に乗せた試料の重さの変化と、熱の発生/吸収を同時に測ることで、試料がどんな変化をしたか（融けた、揮発した、ガラスになった等）を観るものです。

装置自体は1998年にはあったらしく使った4回生さんより年上。しばらくぶりの起動だったものの大きな問題もなく測定できたようです。
