Measurements of the Joule-Thomson coefficient for cryogenic pure fluids and mixtures: experimental data and analysis code

Raw and processed experimental data and the analysis code for measurements of the isenthalpic Joule-Thomson coefficient of pure nitrogen, argon, and helium-4, and of the binary mixtures helium-4-neon and helium-4-nitrogen, at temperatures between 65 and 180 K and pressures up to 10 MPa. Includes raw pressure-temperature(-composition) time series, the extracted isenthalpic p-T pairs, the derived Joule-Thomson coefficients with conventional and Monte Carlo uncertainties, Cernox sensor calibration data, and the Python analysis pipeline. Supporting data for the associated article submitted to the Journal of Chemical & Engineering Data.本数据集包含纯氮气、氩气及氦-4（helium-4），以及氦-4-氖、氦-4-氮气二元体系的等焓焦耳-汤姆逊系数（isenthalpic Joule-Thomson coefficient）测量相关的原始与处理后实验数据及分析代码。实验温度范围为65~180开尔文，压力最高达10兆帕（MPa）。数据涵盖原始压力-温度（-组分）时间序列、提取得到的等焓压力-温度（p-T）对、采用常规与蒙特卡洛（Monte Carlo）不确定度方法计算得到的焦耳-汤姆逊系数、Cernox传感器校准数据，以及Python分析流水线。本数据集为投稿至《化学与工程数据期刊》（Journal of Chemical & Engineering Data）的相关学术论文提供支撑数据。
