Calorimetry question?

Well, the high heat tends to separate the elements of the sample which in turn makes it easier to detect certain elements.

Also the high heat helps to separate the items in the sample to allow better testing to occur.

Calorimetry is the science of measuring the heat of chemical reactions or physical changes. Calorimetry involves the use of a calorimeter. The word calorimetry is derived from the Latin word calor, meaning heat. Scottish physician and scientist Joseph Black, who was the first to recognize the distinction between heat and temperature, is said to be the founder of calorimetry.

Combustion usually involves large heat changes, and from combustion data it is possible to compute enthalpy of formation of some compounds.

Yes and there are photographs of Elvis taken the day after he died coming down the steps of a Private Jet, and we have snapshots of the Loch Ness Monster looking very fishy, and sleepy pie nighty night pictures of Aliens at Roswell looking like they drank too much Booze. And we have Jack the Rippers Diary, a 8mm Movie film of Adolf Hitler doing weight lifting and showing off his muscles. And we have all those photographs of Harry Houdini wearing swimming Trunks. Yes I kid you not, dozens of photographs of Harry in swimming trunks. What is the mystery there you will no doubt ask? Because Harry was always photographed nude standing among crowds of his fans, the trunks were inked onto the photos by prudish American Editors later on.
