Thank you for your reply.

First: I am giving a try if someone working on the topic knows a buffer which has also a white powder in it, to stabilize probably the smell

Second: This group was automatically added by RG, my fault to not have removed it.

Third: Ask to RG

Fourth: I appreciate your effort and I see you are very into the topic to reply in such cleaver way.

Fifth: Next time, instead of reply to something you do not know or you cannot give a contribute, use that time to do something more useful for you.

Have a nice day
