CHI600E</span><span>系列为通用电化学测量系统。下图为仪器的硬件结构示意图。仪器内含快速数字信号发生器，用于高频交流阻抗测量的直接数字信号合成器，双通道高速数据采集系统，电位电流信号滤波器，多级信号增益＋�/span><span>iR</span><span>降补偿电路，以及恒电位仪／恒电流仪（</span><span>660E</span><span>）。电位范围为</span><span>��</span><span>10V</span><span>，电流范围为</span><span>��</span><span>250mA</span><span>。电流测量下限低亍�/span><span>10pA</span><span>。可直接用于超微电极上的稳态电流测量。如果与</span><span>CHI200B</span><span>微电流放大器及屏蔽箱连接，可测量</span><span>1pA</span><span>或更低的电流。如果与</span><span>CHI680C</span><span>大电流放大器连接，电流范围可拓宽丹�/span><span>��</span><span>2A</span><span>、�/span><span>CHI600E</span><span>系列也是十分快速的仪器。信号发生器的更新速率丹�/span><span>10MHz</span><span>，数据采集采用两个同�?/span><span>16</span><span>位高分辨低噪声的模数转换器，双通道同时采样�?*速率丹�/span><span>1MHz</span><span>。双通道同步电流电位采样可加快阻抗测量的速度。某些实验方法的时间尺度可达十个数量级，动态范围极为宽广。循环伏安法的扫描速度丹�/span><span>1000V/s</span><span>时，电位增量仄�/span><span>0.1mV</span><span>，当扫描速度丹�/span><span>5000V/s</span><span>时，电位增量丹�/span><span>1mV</span><span>。又如交流阻抗的测量频率可达</span><span>1MHz</span><span>，交流伏安法的频率可辽�/span><span>10KHz</span><span>。仪器可工作于二，三，或四电极的方式。四电极可用于液</span><span>/</span><span>液界面电化学测量，对于大电流或低阻抗电解池（例如电池）也十分重要，可消除由于电缆和接触电阻引起的测量误差。仪器还有外部信号输入通道，同�?/span><span>16</span><span>位高分辨采样�?*速率丹�/span><span>1MHz</span><span>。可在记录电化学信号的同时记录外部输入的电压信号，例如光谱信号等。这对光谱电化学等实验极为方便、�/span></span></p><div><span><span> CHI600E</span><span>系列硬件采用了高速的处理器，快速的放大器，快速的模数转换器和数模转换器。计时电量法加上了模拟积分器。一�?/span><span>16</span><span>位高分辨高稳定的电流偏置电路以达到电流复零输出，亦可用于提高交流测量的电流动态范围。高分辨的模数转换器具有更好的信噪比，也给出了灵敏度设置的更大动态范围、�/span></span></div><div><span><span> CHI600E</span><span>系列仪器的内部控制程序采用了</span><span>FLASH</span><span>存储器。仪器软件的更新不再需要通过邮寄并更捡�/span><span>EPROM</span><span>，而可以通过网络进行传送并通过程序命令写入。这使得软件更新更加快捷方便、�/span></span></div><div><span><span> CHI600E</span><span>系列还允许升级为双恒电位仪。新的设计通过增加一块第二通道的电位控制，电流电压转换，多级增益和低通滤波器的电路板，便成了</span><span>CHI700E</span><span>系列的双恒电位仪、�/span></span></div><div><span><span> CHI600E</span><span>系列仪器集成了几乎所有常用的电化学测量技术。为了满足不同的应用需要以及经费条件，</span><span>CHI600E</span><span>系列分成多种型号。不同的型号具有不同的电化学测量技术和功能，但基本的硬件参数指标和软件性能是相同的、�/span><span>CHI600E</span><span>咋�/span><span>CHI610E</span><span>为基本型，分别用于机理研究和分析应用。它们也是十分优良的教学仪器、�/span><span>CHI602E</span><span>咋�/span><span>CHI604E</span><span>可用于腐蚀研究、�/span><span>CHI620E</span><span>咋�/span><span>CHI630E</span><span>为综合电化学分析仪，耋�/span><span>CHI650E</span><span>咋�/span><span>CHI660E</span><span>为更先进的电化学工作站、�/span></span></div><div><span></p><p><strong><span>
