Just become involved in a new project utilising Anhydrous Ammonia, and my question relates to the potential to lock-in liquid ammonia between two valves and the potential for expansion.
To relive this it has been advised to use hydrostatic vents, but are there any other options?
Looking for some advice on Si analysis of biomass samples.
The results are showing to be lower than expected, with either looses due to poor on incomplete ashing. HF and microwave digestion, but suspected loss of Si as Silicon tetra fluoride loss during pressure release.
Others tested is HF...
