Abstract 8 pure terpene reagents including limonene were analyzed by using both GC-MS and GC-FID. Here GC-MS was used to identify the impurities in terpene reagent, and GC-FID peak areas were normalized to obtain the purity data of specific terpene reagent. The uncertainty contributions from analytical repeatability, instrumental linearity, FID response factor (effective carbon number(ECN)), and those unknown trace components were evaluated.The measured purity were obtained as following: limonene(98.91%±0.71%), isoprene(99.09%±0.56%), α-pinene(98.91%±0.56%), β-pinene(98.81%±0.48%), α-terpinene(89.26%±0.99%), γ-terpinene(96.65%±0.82%), 2-carene(96.26%±0.76%), myrcene(91.29%±0.84%).
