Hello and thank you for having me!

Hello, I'm new and looking to learn more about testing.

ICP-MS elemental impurities (As, Cd, Hg, Pb, Ni, Cu, Cr, Pd) with numeric results (ppb/ppm)

Endotoxin (LAL)

Sterility or bioburden

Residual solvents (USP <467>)

Counter-ion quantification (e.g., TFA vs acetate)

Karl Fischer water content

Orthogonal HPLC methods + LC-MS identity (mass + sequence confirmation)

Maybe this is overkill. Any thoughts are appreciated. Thank you for your time.
