Preservation of hair stable isotope signatures during freezing and law enforcement evidence packaging

This dataset includes the quality control and complete data for carbon, nitrogen, hydrogen, and oxygen isotope ratio of hair samples stored in different packaging materials and frozen for varying lengths of time. Complete methods and other information is available at the associated article originally submitted to Forensic Chemistry on April 17, 2018.本数据集涵盖了采用不同包装材料储存并经不同时长冷冻的毛发样本的碳、氮、氢、氧同位素比值的质量控制数据与完整原始数据。完整实验方法及其他相关信息可查阅最初于2018年4月17日提交至《法化学（Forensic Chemistry）》期刊的关联论文。
