Applied Photophysics Ltd （ 應(yīng)用光物理公司）生產(chǎn)的型號(hào)為 SX20 的停流光譜儀，在國內(nèi)的清華大學(xué)、武漢大學(xué)、中山大學(xué)、華南農(nóng)業(yè)大學(xué)應(yīng)用多年， 并有很好的高等級(jí)的文獻(xiàn)引用和發(fā)表，數(shù)據(jù)引用率占可檢索到的已發(fā)表的文獻(xiàn)的百分之八十以上。

停流光譜儀相關(guān)說明：

停流（stopped flow）是一種光譜技術(shù)，用于研究溶液體系的非常快速的反應(yīng)的機(jī)理，反應(yīng)的時(shí)間一般在0.001秒到0.01秒之間，這個(gè)瞬時(shí)動(dòng)力學(xué)現(xiàn)象可反映反應(yīng)的速度、機(jī)理、短時(shí)間存在過的反應(yīng)中間體等基礎(chǔ)信息。

可選擇配置的功能模塊為：時(shí)間分辨的吸收分析、管陣列檢測(cè)器、雙熒光檢測(cè)、熒光偏振檢測(cè)，多通道序列混合系統(tǒng)、淬滅停流檢測(cè)，及CD圓色停流stopped flow分析系統(tǒng)等。

The SX20 is the latest in the SX range of stopped-flow reaction analysers from Applied Photophysics and is used to study transient and pre-steady-state kinetics of fast, liquid-phase reactions. The SX range has, since its introduction over 15 years ago, established itself as the first choice of those involved in stopped-flow kinetic research. The SX20 and its predecessors offer unrivalled performance, as well as a host of upgrade opportunities for the detailed investigation of chemical and biochemical reaction mechanisms.
