仪器与硬件

一些研究人员在测试中想要能够施加或者测量高于12V的电压值。其中一个有高电压需求的例子就是电池测试，而另一个可能是微流体通道内部的循环伏安法。也许您想要进行某些类型需要高压的电沉积实验。在这些情况下，您可能需要加大力度去寻找一台能够在如此高的电压下运作的电化学工作站。

这个技术报告的目的在于帮助您更好地了解电化学工作站的功能和各项技术参数。规格说明书里常提到的典型参数在报告中都做了相应的解释。另外，该报告还显示了哪些参数与实际应用较为相关，同时指出了应用中需要注意的地方。

电化学工作站 是一种控制工作电极和参比电极之间电位差的电子仪器。其中，工作电极和参比电极都是电化学电解池里的组成部分。

每个人都同意理想的参比电极具有稳定性，即明确的电化学电势。常见的参比电极，例如SCE, Ag/AgCl, Cu/CuSO4，在正常工作时都符合这个标准。

This application note describes the software changes that you can make to slow down a Gamry Instruments’ potentiostat. Slowing down the potentiostat can improve its stability. These changes presume a working knowledge of Gamry Instruments’ Explain™ scripting language.

When performing experiments with dye solar cells, light is focused on the cell and its current response is measured. The generated current depends strongly on the intensity of the light. In order to calculate the efficiency of a solar cell, the optical power of the incident light has to be known. This technical note explains how to measure and calculate the optical power of your light source.

This application note is meant to provide you with several tips and techniques for improving potentiostat stability. Potentiostats can become unstable for several reasons. Improving the stability may require trying several different techniques.

If you suspect that your Gamry Potentiostat is misbehaving, the first step is to calibrate it. The Calibration element on the UDC 4 is a 2000 ohm precision resistor (with some protection components).

This application note will discuss the limiting factors controlling low current measurements. It will include hints on cell and system design. The emphasis will be on EIS (Electrochemical Impedance Spectroscopy), a highly demanding application.

Vycor® is often used at the end of a reference electrode or a bridge tube to allow electrical, ionic conductivity between the bulk of the solution and the internal filling solution, while preventing large scale convective mixing of the solutions. Vycor, or "thirsty glass" is a porous glass with a fairly low leak rate.
