CD圆色光谱仪 Chirascan and Chirascan-plus Circular Dichroism Spectrometers
Chirascan and Chirascan-plus 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)技术,用于研究溶液体系的非常快速的反应的机理,反应的时间般在0.001秒到0.01秒之间,通过研究瞬时动力学现象可反映反应的速度、机理、短时间存在过的反应中间体等基础信息。 Applied Photophysics Ltd ( 应用光物理公司) 生产的型号为 SX20 系列的停流光谱仪,数据引用率占可检索到的已发表的文献的八成以上。可选择配置的功能模块为:时间分辨的吸收分析、管阵列检测器PDA 、双荧光检测、荧光偏振检测,多通道序列混合系统、淬灭停流检测、电化学检测CD圆色停流分析系统等

SX20 停流光谱仪 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 快速混合停流装置,可与各种型号的紫外可见分光光度计(如Agilent 8453, 瓦里安 Cary  50,100, 300 等)、荧光光谱仪(如日立 Hitachi 荧光 F-4000, F-4500, F-4600, F-7000等各型号荧光光谱仪, 瓦里安系列荧光光谱仪、PE各型号荧光光谱仪等)、CD光谱仪联用,研究毫秒的快速动力学反应。小巧方便,经济适用。 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.

纳秒激光闪解分析仪(瞬态吸收光谱仪)LKS.80 Nanosecond Laser Photolysis Spectrometer用于纳秒、微妙时间量范围内的动力学分析,通过瞬态吸收光谱研究来探究动力学过程, 包含时间分辨光谱分析,灵敏度,响应时间短, 时间分辨率可以到0.1纳秒 ,多种激光装置可以选择 。
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
