不同水体的氢氧稳定同位素可用于植物▲水分利用来源、水汽输送、土壤水运移和补给〓机制、补给源和地下水机制、水体蒸发、植物蒸腾和土壤蒸发的区分、径流的形成和汇合、重建古气候等方面的研究。因而引起了水文学家，生态学家以及气候学家等的广泛关注。但问题是：在进行水稳定同位素测试之前如何将植物木质部和ξ 土壤中的水分无分馏的提取出来？
LI-2100是LICA自主研发的一款全自动真空冷凝抽提系统，且已通过CE认证。从根本上解决了植物和土壤№水分提取的难题，克服了传统液氮冷却的繁琐，不仅可以防止同位素分馏，而且安全高效，不会对植物和土壤造＠ 成破坏。可与LGR水同位素分析仪∩和质谱仪配套使用。许◣多科学家已经结合LI-2100和LGR的水同位素分析仪进行了诸多研究。
从研发生产╳至今，LI-2100在国内已经销售了近百台，国内的科研工作者利用这台仪器发表了诸多文献，得到了用户的众多好评。
随着LI-2100在国内的广泛应用及众多文献的发表，国外的一些科学家也开始关注理加公司研发生产的LI-2100，理加公司也积极在海外推广】该产品，由此拉开了LI-2100走出国门、走向海外的序幕。
