摘 要: 系统地介绍了气相色谱用马尾松松香标准样品的定值方法。采用单一方法通过6家实验室联合定值,得到标准样品中7种树脂酸的GC含量(%)的特性值和扩展不确定度:海松酸8.2683±0.3203;山达海松酸:1.7433±0.3199;异海松酸:0.7652±0.3118;长叶松酸:30.8201±1.3668;去氢枞酸:3.2731±0.8693;枞酸:34.9275±1.2664;新枞酸:18.7469±1.8494。 This paper provides method of certification report of reference materials of P. massoniana Lamb. rosin for GC analysis. The property and uncertainty value on the content( GC% ) of seven resin acids from reference materials was made certain by six laboratories united-certification. They are pimaric acid: 8. 2683 ± 0. 3203, sandaraeopimarie acid: 1. 7433 ± 0.3199, isopimaric acid : 0. 7652 ± 0.3118, palustric acid: 30. 8201 ± 1. 3668, dehydroabietic acid: 3. 2731 ± 0. 8693, abietic acid: 34. 9275 ± 1. 2664, neoabietie acid: 18. 7469 ± 1. 8494.
