高效液相色譜法(High Performance Liquid Chromatography,HPLC)是一種基于液相色譜原理的分離分析技術,通過高壓驅動流動相(液體)攜帶樣品通過填充有微米級顆粒的色譜柱,利用不同組分在固定相與流動相間的分配差異實現分離。其核心原理包括分配平衡、吸附作用和分子篩效應,常用于藥物分析、環境檢測、食品安全和生物化學研究領域。
該技術的關鍵組件包括:
根據美國藥典(USP)定義,HPLC的分離效率可達理論塔闆數40,000-100,000/米,靈敏度可達納克級(ng)。例如在藥物質量控制中,HPLC可檢測藥品中0.1%的雜質含量,滿足國際藥品注冊技術協調會(ICH)的嚴格标準。國際純粹與應用化學聯合會(IUPAC)将其歸類為現代分析化學的四大支柱技術之一。
最新研究表明,超高效液相色譜(UHPLC)通過使用亞2 μm填料顆粒,在保持分離度的同時将分析時間縮短至傳統HPLC的1/9,該技術已被《分析化學》期刊列為21世紀分析科學的重要突破。
High Performance Liquid Chromatography(HPLC,高效液相色譜法)是一種廣泛應用于化學、生物、醫藥等領域的分離分析技術。以下從定義、原理、應用等方面詳細解釋:
HPLC全稱為高效液相色譜法(),是色譜法的重要分支,以液體為流動相,通過高壓系統驅動樣品通過色譜柱,實現混合物中各組分的分離與定量分析。
HPLC也被稱為高壓液相色譜或高速液相色譜(),其英文縮寫“HPLC”更為常用。
通過綜合高壓技術、高效固定相和靈敏檢測手段,HPLC成為現代分析化學中不可或缺的工具。如需更詳細原理或操作步驟,可參考專業文獻或儀器手冊。
