200 microliters to ppm?
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

Dissolve it in liters of something? ppm is a ratio, parts of some substance dissolved in one million parts if solution.
Also ppm is completely ambiguous unless you specify whether is is a volume ratio, mass ratio, or mole fraction ratio. The term is therefore deprecated in the SI.
