Title:
METHOD FOR MEASURING SAMPLE LENGTH AND THERMAL EXPANSION IN THERMOMECHANICAL ANALYZER
Document Type and Number:
Japanese Patent JP2759770
Kind Code:
B2
Abstract:
PURPOSE: To facilitate measurement operation by automatically obtaining the length of a measurement sample at a reference temperature using a thermomechanical analyzer(TMA).
CONSTITUTION: A total reference sample and a length-measurement reference sample whose total length LO at a reference temperature is known are arranged in a support pipe to detect a difference ΔLO in the relative length of a reference sample whose length is to be measured to the total reference sample at the reference temperature. Then, the total reference sample and the measurement sample are arranged in the support pipe to detect a difference ΔL1 in the relative length of the sample to be measured to the total reference sample at the reference temperature. Then, a total length L1 at the reference temperature of the sample to be measured is calculated based on the total length LO, the relative length difference ΔLO of the measurement reference sample, and the relative length difference ΔL1 of the sample to be measured.
