摘要：研究了马尾松松节油标准样品的均匀性、稳定性及其定值方法。马尾松松节油标准样品中4种指标成分的含量测定采用气相色谱面积归一化法。制备得到的马尾松松节油标准样品通过了均匀性检验,且在36个月内是稳定的。马尾松松节油标准样品的多实验室联合定值结果为:α-蒎烯含量的标准值84.63%,标准不确定度0.12%,扩展不确定度(95%置信率)0.24%;β-蒎烯含量的标准值9.56%,标准不确定度0.07%,扩展不确定度(95%置信率)0.14%;苧烯含量的标准值1.66%,标准不确定度0.03%,扩展不确定度(95%置信率)0.06%;长叶烯含量的标准值0.43%,标准不确定度0.04%,扩展不确定度(95%置信率)0.08%。
Homogeneity,stability and certification of reference materials for masson pine（Pinus massoniana Lamb.）turpentine oil were carried out.The content of 4 indicating of components of the reference material was measured using gas chromatographic area normalization method.The standard of turpentine oil reference of masson pine passed the test of homogeneity,and it was stable during 36 months at least.The evaluation results of the reference by different labs show that the standard value of 4 indicating components contents were as follows： α-pinene content of 84.63 % with standard uncertainty of 0.12 %,extended uncertainty of 0.24 % and confidence coefficient of 95 %;β-pinene content of 9.56 % with standard uncertainty of 0.07 %,extended uncertainty of 0.14 % and their confidence coefficient is 95 %;limonene content is 1.66 % with standard uncertainty of 0.03 %,extended uncertainty of 0.06 % and confidence coefficient of 95 %;longifolene content is 0.43 % with standard uncertainty of 0.04 %,extended uncertainty of 0.08 % and confidence coefficient of 95 %,respectively.
