Abstract

The invention belongs to the field of sample analysis instruments and discloses a thermal gravimetric analyzer capable of realizing rapid temperature rise. The thermal gravimetric analyzer comprises a weighing device, a heating furnace, a sample lifting device, a protective lifting device and a temperature control device, wherein the weighing device comprises a pedestal base and an electronic balance; the heating furnace comprises a furnace holder and a furnace body; a resistive heater, a lofting channel, a reaction gas inlet pipe and a reaction exhaust outlet pipe are arranged on the furnace body; the sample lifting device comprises a first power mechanism, a first transmission device, a lifting table and a lifting rod; the protective lifting device comprises a second power mechanism, a second transmission device and an insulated protective jacket; and the temperature control device is connected with the heating furnace to be used for controlling the temperature of the hearth. According to the insulated protective jacket disclosed by the invention, the lifting basket is protected, abnormal data fluctuation at the initial reaction stage can be eliminated, and the measurement integrity, reliability and accuracy are improved.

Description

technical field [0001] The invention belongs to the field of sample analysis instruments, and more specifically relates to a thermogravimetric analyzer capable of rapid temperature rise. Background technique [0002] Thermogravimetric analyzer refers to an analytical instrument that accurately measures and records the quality of a substance as it changes with temperature under a certain program control temperature. It can reflect the change law of the quality of a substance during heat treatment and is widely used in chemical energy, environment and other fields. The conventional method of using thermogravimetric analyzer is the temperature programming method (non-isothermal method), which means that the temperature in the furnace gradually rises according to the program setting during the sample reaction process. Component analysis, substance identification, determination of thermal parameters and kinetic parameters, etc. Recently, in some scientific researches, it is nec...
