method development for residual solvents (MeOH, EtOH, Acetone & hexane) in solid (powder) samples. Any application notes or technical reports available that may help me?

Hi smeszaros,

I have added a couple of tags. Please let us know the instrumentation you are using? Headspace etc?

Regards

James

Hello,

For Ethanol I would suggest that you use a CP-Wax 52CB Part CP7668i.

Use it with your Headspace.

Try to add water to your powder and measure it with your Headspace at around 90°.
