Unknown brown particles
 
4 Attachment(s)
Hi all,

We have received a sample of brown particles that we are trying to identify but are coming up blank. Infra-red analysis of the particles shows that they are cellulosic, but they are not seeds or pollen grains.

They are approximately 0.5 x 0.4mm and have 6 sides.

Any help on this would be greatly appreciated.

Thanks

Very hard to say anything without knowing more about your sample.
- origin?
- size? (I can't distinguish the bar in the pic)
- Do they have a homogenous size and shape?
- What do you want to know? What information do you need?

BTW to know if its cellulose you just have to make a lugol reaction.
