OK I managed to catch it and add it.

I should note that "technically" the ortho P has a 48hr hold time when testing to lab standards for permitting etc. Also Total P and N require that the sample be stabilized with sulfuric acid.

My sample met neither of those, but for the level of accuracy that we are after here should be just fine.

Due to the specialized nature of the testing they do they have several different bottle sizes and pre treatment specs. There's really no way to fill out the form to have a single quart bottle separated (via pour off) to do other tests, but calling in they understand and can do so.
