不同水體的氫氧穩定同位素可用于植物水分利用來源、水汽輸送、土壤水運移和補給機制、補給源和地下水機制、水體蒸發、植物蒸騰和土壤蒸發的區分、徑流的形成和匯合、重建古氣候等方面的研究。因而引起了水文學家，生態學家以及氣候學家等的廣泛關注。但問題是：在進行水穩定同位素測試之前如何將植物木質部和土壤中的水分無分餾的提取出來？
LI-2100是LICA自主研發的一款全自動真空冷凝抽提系統，且已通過CE認證。從根本上解決了植物和土壤水分提取的難題，克服了傳統液氮冷卻的繁瑣，不僅可以防止同位素分餾，而且安全高效，不會對植物和土壤造成破壞?？膳cLGR水同位素分析儀和質譜儀配套使用。許多科學家已經結合LI-2100和LGR的水同位素分析儀進行了諸多研究。
從研發生產至今，LI-2100在國內已經銷售了近百臺，國內的科研工作者利用這臺儀器發表了諸多文獻，得到了用戶的眾多好評。
隨著LI-2100在國內的廣泛應用及眾多文獻的發表，國外的一些科學家也開始關注理加公司研發生產的LI-2100，理加公司也積極在海外推廣該產品，由此拉開了LI-2100走出國門、走向海外的序幕。
