Claim 8:
9. A method of providing an environment of droplets or particles while maintaining a specified concentration of a vapor and/or gas in an enclosure, the method comprising:
positioning an injection station within the enclosure, the injection station comprising:
a material source comprising a droplet and/or particle;
a liquid or gas in which the droplet and/or particle is suspended or dissolved;
a sprayer assembly; and
a system that delivers the droplet and/or particle to the sprayer assembly;

monitoring a concentration level of the environment surrounding the droplets or particles of the droplets or particles of the liquid and/or gas in which the droplets or particles are suspended or dissolved using a sensor located outside of a housing of the injection station and exposed to the environment to directly monitor the concentration level outside of the housing; and
sending the monitored concentration to a controller controlling a flow rate to the sprayer assembly of the liquid or gas in which the droplets are suspended or dissolved, based on the monitored concentration level and at a specified setpoint or range.
