Equipment
Gases
[From the wall out]
- Helium UHP [LTQ] (40psi)
- Nitrogen UHP [HCD] (100psi)
- Nitrogen 99% (this is the normal nitrogen in the stock room) [sheath & Orbitrap bath] (100psi)
- Nitrogen? Normal? psi? [for UPLC]
UPLC
- Troubleshooting the Eksigent UPLC system
- UPLC (Fittings/tubing/flow rates)
- 10 micron needles provide best nano-spray at 200-300 nl/min
