A thermogravimetric analysis instrument and method for calculating a weight of a sample in a thermogravimetric analysis appliance

摘要

A thermogravimetric analysis device, comprising:(a) a balance (300);(b) a ladle (450) for holding a sample;(c) a filament (112, 114), which connects the ladle by means of the balance;(d) a furnace (104), in order to heat the sample;(e) a thin metallic tube, which surrounds the filament and heat shields attached thereto; and(f) comprises means for calculating a corrected weight (m) including a means for measuring a weight of the sample (m_s) and a means for calculating a buoyancy factor, wherein the means for calculating a buoyancy factor calculating a buoyancy factor for the sample (b_s) in accordance with comprises.
