1a. Program for Continuous Controlled Vaporization
Chromatographic molecular separation and time-temperature based diffusion of a cross section of commercially produced substances* using HeraTherm Advanced Protocol oven† with programmable temperature increase.
Substances (including natural and artificial flavors, cosmetics and cleaning products) are separated into their individual molecular components, each one of which has a distinct olfactory profile (or in some cases may be odorless). Each of these component molecules is vaporized and diffused into the surrounding air at a specific time within the oven sequence based on its boiling point and its interaction with a chromatographic sorbent as the oven temperature gradually rises.
Three programmable ovens are used in an alternating sequence to fully vaporize one substance per hour. The same hourly oven program is used on all substances:
(warm up to 60 °C 10 minutes prior to program initiation) starting temperature 60 °C + 4.0 °C per minute increase for 60 minutes (to 300 °C) hold 300 °C for 5 minutes (cool down) 2014 – 2015, dimensions variable
1b.
Negative Air
Airborne vaporized materials produced by 1a. are re-collected by an Omniaire 600V negative air machine with an activated carbon filter. The separated and volatized compounds are re-condensed onto the filter in the original ratio of the mixture prior to diffusion, transporting the formulation from one location to another within the space. All vaporized materials are collected onto the filter throughout the exhibition and the filter consists of the overall average of the component molecules of all vaporized formulations.
