Residual solvents testing labs

[qcChemist]

Does anyone know of any testing labs that specialize in residual solvents <467> testing? We need a sample tested for residuals, and we don't have the equipment to do it, so we need to send it out. The usual company we go through, Exova, doesn't seem to know what we are talking about.

Residual solvents <467> is a USP methodology. If it's USP methods you need try here http://www.irvinepharma.com/irvinelocations.asp

I'm Lab Sercices Manager at POS Pilot Plant http://www.pos.ca/about//. We perform residual solvent anaysis by GC/MS for clients. However, we don't use the USP methodology.
