ISO9000 for CNTs

One of the major issues plaguing anyone making use of carbon nanotube is the variability between batches, production methods, and suppliers.

There is a wide spread of parameters, for example in single walled nanotubes (SWNTs) involving the ratio of nanotubes to carbon, the amount of left over catalyst, ratio of metallic to semiconducting nanotubes etc. The situation is compounded by the lack of any standard for analyzing nanotubes. All of this has been the cause of major headaches for end users of nanotubes who often find that one batch may work fine with their process, while another won’t works quite as well.

Zyvex have started down this path with the announcement of its Supply Chain Certification Program for carbon nanotube suppliers. This is a step in the right direction, but industrial history is littered with failed standards, and it is not uncommon for standards to vary widely (pretty much every government has its own standards agency).

Getting from an internal standard to an internationally recognised one recognised by ISO (International Organization for Standardization) for example may be trickier.

Cientifica staff have been involved in several international standards, and we can promise that it will take a lot of meetings and quite a few years to get anywhere near an ISO standard.
