Green coffee bean isotopes have been used to trace the effects of different climatic and geological characteristics associated with the Hawaii islands. Isotope ratio mass spectrometry (IRMS) and inductively coupled plasma mass spectrometry ((MC)-ICP-SFMS and ICP-QMS) were applied to determine the isotopic composition of carbon (δ13C), nitrogen (δ15N), sulfur (δ34S), and oxygen (δ18O), the isotope abundance of strontium (87Sr/86Sr), and the concentrations of 30 different elements in 47 green coffees. The coffees were produced in five Hawaii regions: Hawaii, Kauai, Maui, Molokai, and Oahu. Results indicate that coffee plant seed isotopes reflect interactions between the coffee plant and the local environment. Accordingly, the obtained analytical fingerprinting could be used to discriminate between the different Hawaii regions studied.
绿咖啡豆同位素已被用于追踪与夏威夷群岛相关的不同气候和地质特征的影响。同位素比质谱（IRMS）和电感耦合等离子体质谱（MC-ICP-SFMS 和 ICP-QMS）被应用于测定碳（δ13C）、氮（δ15N）、硫（δ34S）和氧（δ18O）的同位素组成、锶（87Sr/86Sr）的同位素丰度以及 47 种绿咖啡中 30 种不同元素的浓度。这些咖啡产于夏威夷的五个地区：夏威夷、考艾岛、毛伊岛、莫洛凯岛和瓦胡岛。结果表明，咖啡植物种子的同位素反映了咖啡植物与当地环境之间的相互作用。因此，所获得的分析指纹图谱可用于区分所研究的不同夏威夷地区。
