CD圓二色光譜儀 Chirascan and Chirascan-plus, Chirascan V100 Circular Dichroism Spectrometers
Chirascan and Chirascan-plus, Chirascan V100 are the world's most advanced circular dichroism (CD) spectrometers. They are widely used in the study of the higher structures of bio-macromolecules, such as proteins and DNA, and how these structures change on interaction with other molecular entities. Their many innovative features provide the scientist with easy-to-use, productive tools that deliver circular dichroism spectra of a quality and on a timescale that has until recently been impossible.
停流(stopped flow)技術,用于研究溶液體系的非??焖俚姆磻膭恿W機理,反應的時間一般在0.001秒到秒時間量級,通過研究瞬時反應動力學現象可反映反應的速度、機理、短時間存在過的反應中間過渡態等基礎信息。英國 Applied Photophysics Ltd ( 應用光物理公司) 生產的型號為 SX20 系列的停流光譜儀,以及之前的系列如SX 18 MV, SX 17 , SX 15 , SX 12 等,數據引用率占可檢索到的已發表的文獻的八成以上??蛇x擇配置的功能模塊為:時間分辨的吸收分析、二級管陣列檢測器PDA 、雙熒光檢測、熒光偏振FP (Fluoresence Polarization )檢測,多通道序列混合系統、淬滅停流(Quench Flow ) 檢測、電化學檢測,及CD圓二色停流分析系統等
SX20 停流光譜儀 SX20 Stopped-Flow Spectrometer
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.
RX.2000 快速混合停流裝置,可與多種型號的紫外可見分光光度計(如Agilent 8453, 8454 , 瓦里安 Cary 50,100, 300 , 3000等)、熒光光譜儀(如日立 Hitachi 熒光 F-4000, F-4500, F-4600, F-7000等各型號熒光光譜儀, 瓦里安系列熒光光譜儀、PE各型號熒光光譜儀等)、CD光譜儀聯用,研究毫秒時間量級的快速動力學反應。小巧方便,經濟適用。 RX.2000 Rapid Mixing Stopped-Flow Unit
The RX.2000 provides the means to measure stopped-flow rapid reaction kinetics using any UV-visible spectrometer, fluorometer or CD spectropolarimeter. This high performance, cost effective unit enables reactions to be studied that are at least a thousand fold faster than those accessible manually.
納秒激光閃解分析儀(瞬態吸收光譜儀)LKS.80 Nanosecond Laser Photolysis Spectrometer,用于納秒、微秒時間量范圍內的動力學分析,通過瞬態吸收光譜研究來探究動力學過程, 包含時間分辨光譜分析,靈敏度,響應時間短, 時間分辨率可以到0.1納秒 ,多種激光激發裝置可以選擇 。
Applied Photophysics has been supplying laser flash-photolysis instruments since 1973. The experience gained during this period has resulted in the LKS.60 spectrometer which offers both ease of use and flexibility, including special configurations such as combined stopped-flow and/or flow-flash systems. The LKS.60 is used to study the reactions of very short-lived species, such as free radicals or excited state species
