Application Note

Use of the STA 8000 Simultaneous Thermal Analyzer for Melt Analysis of Alloys


The requirements for melt analysis of alloys include accurate temperature and melt energy measurement and the ability to exclude oxygen – or if necessary, nitrogen – during the analysis. With the ability to provide microgram-level weight change detectability of sample loss or oxidative gain, Simultaneous Thermal Analysis is a well-suited analytical technique for the determination of the composition of alloys.

This application note describes how the PerkinElmer STA 8000 analyzer is used to accurately analyze melting characteristics of two high temperature melting systems, including iron-nickel alloys which require oxygen exclusion.
