Oxalic acid sublimator / vaporiser

[Gilberdyke John]

But is a sublimate particulate or gaseous?

Gaseous when it leaves the surface of the heated stock but by the time its leaving the end of the tube its temperature has dropped so it's a fine particulate. Certainly by the time its travelled a short distance through open atmosphere it'll be condensed back into a solid

Sublimated oxalic acid is an organic vapour (in the chemistry sense of organic rather than Soil Association ) so filter A2P3 is required.
