I can't remember what I was looking for when I stumbled accross this forum but I am very glad I did, I have learnt loads from browsing the archives over the past week.

I've been working as an analytical chemist for two years now, so for the now I will ask more questions than I answer (then again I've found whenever I answer a question in this job the answer contains 3 more questions...)

Many thanks to those who set up the forum and keep it running, they have done and are doing a tremendous job, it's a great service for us! Hopefully in time I will become one of the many trusty regulars (you know who you are) whose pearls of wisdom keep the forum going.

All the best to you all, Pat.
