PB: particle beam


Explanation:
I could find this explanation of the abbreviation PB -> see page 3:

Regarding BB, I'm trying to find some more reference information.
HTH :-)

See also this journal article - right at the beginning, in the abstract:

PB: pencil (!) beam
BB: broad beam

To make it even more confusing, BB also stands for broad-band ...!

So, after some Google research, I am quite convinced of PB being particle beam, but as for BB (broad beam or broad band?) any physicist around here should pls. provide his/her input ;-)

PB: phosphate buffer & BB:Bacillibactrin


Explanation:
In a high performance liquid chromotography (HPLC) there is an internal standard and a biological speciman. In this case the PB which is the phosphate buffer is the internal standard to which the biological speciman is compared (BB). This could be the strain Bacillibactrin.

As far as I know HPLC is a biochemistry test and therefore the analites are all chemicals. Indometacine is also a chemical drug.

Sorry, I suggest you ask the client what BB and PB stand for. Without more context I am unable to help you.

In all scientific papers it is standard practise to write out the abbreviation when it is used for the first time, e.g SIDS (Sudden infant death syndrome) and thereafter they just make use of the abbreviation. I wish all writers would follow this practise, that would stop us guessing and wondering. I have one of those minds that just would not let go....
