Publications utilizing Syringeless
Injection Techniques 1991 to 2000
Paper describing the operation and design of the Syringeless Injector.
Some of the examples include, identification of an odor problem
from roofing material. Determining the cause of damage to electrical
power cables from three different sources, droplets of rodenticide,
agricultural chemicals and an oil spill.
