“…Friedenberg and Jannke (143) extended Herrington's (180) work, developing and applying expressions relating the difference in AT slopes obtained on heating and cooling milligram samples and Cu cone reference in a Dewar. Although the experimental procedure was long, heating rate of 0.016°C /minute with a 5-hour soak time, the establishment of method constants would make routine measurements rapid and automatic with a specific system.…”
