Unified name for added or lost "fragments" in Mass Spec

[sbashkyrtsev]

There are different ways an analyte can react in Mass Spec. It can:
- Receive a positively charged ion like H+
- Receive a negatively charged ion like H-
- Loose a neutral fragment like BOC
- Receive a nuetral fragment
- And it can be fragmented into 2 ions

I'd like to create a table with all of these included. But I don't know how to name such table. It would contain something like:

Code: Select all

Change  | Effect on Analyte charge
[M+H]   | +1
[M+Na]  | +1
[M-BOC] | 0

Some people call them adducts (which doesn't seem to make sense when it's removed), others - fragments (which doesn't make sense when it's added). Is there some common term that would unite these?

Species?

If this table is just for internal or personal use, that would be a good broad, general term.

Naah, that's too generic Seems like there's no common term and I'd just have to list them as Adducts, Fragments, Ions.
