Conductive Ionic SEM coating fluid      

Introduction

The BEL-1 conductive ionic SEM coating fluid offers a simple and cost-effective alternative for coating non-conductive sample with a conductive surface layer. Instead of using a sputter coater with a precious metal target, the sample needs to be immersed in a diluted conductive SEM coating solution for several minutes. 

Features of the BEL-1 conductive ionic SEM coating fluid are: 

• Excellent permeability and high electrical conductivity 
• Water-soluble and environmentally friendly coating agent for SEM observation 
• Compatible with most non-conductive materials and fixed biological samples 
• Based on polythiophene conductive polymer 
• Conductivity: 250 S/cm 
• Efficient in use 
• Dilution, immersion and drying procedures can enhance conductivity 
• Best results obtained with 1-3kV SEM beam voltage 

The BEL-1 conductive ionic SEM coating fluid needs a 10-20x dilution when used. Only prepare the amount which is directly needed and do not store diluted fluids. The sample must be immersed and completely dried afterwards using a blower. 
Storage of the BEL-1 conductive ionic SEM coating fluid should be preferably at 4-8 °C, but since it is water based: Do not Freeze.
