ABSTRACT:
A sample delivery module for use in conjunction with a particle acceleration apparatus includes a fitting for connecting the sample delivery module to the apparatus. The sample delivery module provides a particle acceleration path which includes a portion adapted to receive a sample of particles coated with a biological material, a particle acceleration chamber coaxial with, and in fluid communication, with the cartridge chamber, and a substantially conical exit nozzle coaxial with and in fluid communication with the particle acceleration chamber. In use, a gas stream causes sample particles to be entrained therein and accelerated through the particle acceleration chamber and the exit nozzle toward a target.
