There are three levels of pH dependance in eLBOW at the moment. From the
--pH=PH specify --pH=low to retain exact input chemistry
--pH=neutral to remove hydrogens from acids ...
--pH=high to add hydrogens to amines
Neutral pH (the default) also removes hydrogens from phosphates.
If you are referring to in situ pH calculations, its on the list.
