摘　　要：从仪器管理的角度,对不同型号的3台热重分析仪的基线、重复性、维护便利性等进行了分析比较。结果表明,悬挂式热重分析仪基线漂移范围在30μg以内,而水平式热重分析仪测试结果的可重复性最佳。对于有大批样品量的测试平台,建议选择带有抓手式自动进样器的热重分析仪。From the viewpoint of instrument management,the baseline,repeatability and maintenance convenience of three thermogravimetric analyzers of different types are analyzed and compared.The results show that the baseline drift of the suspended thermogravimetric analyzer is within 30 μg,while the horizontal thermogravimetric analyzer has the best repeatability.For the test platform with a large number of samples,it is recommended to select a thermogravimetric analyzer with a grasping automatic sampler.
