I am looking for protocol for pH measurments in liquid using orange acridine (pH range 5-7). If someone has this protocol tahat would be grat! thanks

I treat arabidopsis seedlings in liquid culture with flagellin and want to track pH changes over 40 min by taking aliquots of 100 ul and measuring pH. Any other idea to do so is appriciated. Thanks

What is the degassing temperature and time for biochar for BET surface area analysis if TGA is not possible?

Since BET and TGA both are very costly instruments and many places the facilities are not available (for large number of samples) hence a threshold degassing temperature and time is preferable

Thomas Miles

Do you have a characterization of the chars that have shown toxicity? And the results? Thanks

Patryk Oleszczuk

Thanks Xavier, it's really helpful.

Hi Patryk:

Hope you are doing good. I think this due to present of Oxygen which will reduce the PAH as this would generate a complete combustion of organic compounds and this will reduce PAH formation.
