使用银而不是金作为扫描电子显微镜的导电涂层具有相当大的优点，即由于络合离子的形成，随后可以用中性水溶液试剂去除银膜。Farmer‘s Reducer’含有铁氰化物和硫代硫酸盐离子，以一种特别温和的方式完成了对银的去除，而不会对各种底物产生有害影响。在图像稳定性和分辨率方面，银涂层似乎与金涂层相当，但长期存储确实需要采取预防措施，以防止褪色。
Abstract Use of silver rather than gold as a conductive coating for scanning electron microscopy has the considerable advantage that a silver film may subsequently be removed with neutral aqueous reagents, as a result of complex ion formation. ‘Farmer's reducer’ contains ferricyanide and thiosulphate ions, and accomplishes the removal of silver in a particularly gentle manner without deleterious effects upon a variety of substrates. The silver coating appears equivalent to gold as regards image stability and resolution, but long-term storage does necessitate precautions to prevent tarnishing.
