What about those parameters that do require field preservation?


Whenever there is a requirement, Torrent will provide pre-preserved containers that are clearly marked with the type of preservative and the parameter of its use. Examples of these are:
VOC analysis which are almost always collected in HCl preserved vials and Total Sulfides which are collected in NaOH/Zinc Acetate preserved bottles. When in doubt, call your Torrent Project Management Team. We will be happy to assist you.
