Headspace analysis of powders

I have Agilent 7697A Headspace Sampler.  Sometimes I need to run fine powders (e.g. salts).  I have experienced sudden loss of sensitivity that went away after sampling needle was cleaned.  I think this was caused by small solid particles entrained with the carrier gas. 

 

Is there an accessory for keeping solids in the vial?  For now I wrap samples in a lint-free tissues and run tissue in a vial as a blank.
