Hi everybody,
in the lab where i work we are going to change the "not so good" ultimate 3000 with another HPLC.
I premise that the HPLC it's coupled to an API 4500 QTrap.

The 3 HPLCs availables are:
- Agilent 1200 SL - demo version
- Shimadzu XR - demo version
- Shimadzu Nexera - brand new

please, tell me your opinion ;)
