Electronics Purification

Electronics purification

The use of organic molecules within electronics has increased tremendously with significant growth in the use of materials such as liquid crystal displays, organic light emitting diodes, organic field effect transistors and organic solar cells to name a few. The presence of metal impurities in these organic materials can have a significant detrimental effect on the product performance and lifetime. The metal impurities can come from the raw materials or the processes used to make the products. PhosphonicS products are able to remove most metals to below ppm levels giving improved performance so whether you want to remove metals from your starting materials, intermediates or products PhosphonicS have solution for you.

What Makes PhosphonicS Unique?

PhosphonicS uses patented technology for attaching powerful ligands to a silica backbone. The ability to incorporate multiple chelating sites enables our silica products to outperform other solid supported products, at every concentration of precious metal in your stream.

Case Studies

Metal removal from LCD material

A liquid crystal materials manufacturer wanted to remove a range of 20 different metals including group 1, group 2 and transition metals from their product. Batch to batch variability in metal content resulted in varying electro resistance of the product.

PhosphonicS screened a range of products and where typical purification products would remove specific groups of metals, PEP13 was able to remove all the metals simultaneously to low levels. Optimisation of the process through a PhASE program allowed the effective use of the material in a packed column at 50 °C. the fixed bed column gave both the greatest removal and the most efficient use of scavenger. The treatment process reduced all the metals varying from 1 to 100ppm to less than 0.1ppm and resulted in a more uniform product with an increase of the electric resistance of between 60 and 300%.
