Abstract
A wet standard calibration system which utilizes a heat conducting foam with the liquid therein to serve as a primary heating device to avoid the need to include mechanical agitation. The system is particularly useful for generating a vapor comprising water and ethanol which can be used for the calibration of breath alcohol testers.
Claims20
A wet calibration system comprising:
- a vessel;
- a thermally conductive foam placed within said vessel so as to take up a portion of an internal volume of said vessel, a remaining portion of said volume not taken up by said foam comprising a headspace, said headspace including a gas;
- a liquid mixture:
- said liquid mixture including a solvent and a solute;
- and
- said liquid mixture being in thermal contact with said thermally conductive foam;
- and
- a heating element;
- wherein, said heating element heats said thermally conductive foam;
- wherein said thermally conductive foam heats said liquid mixture to a temperature;
- and
- wherein heating of said liquid mixture generates a vapor in said headspace, said vapor having a concentration of solute relative to said temperature.
9 more elements
A wet calibration system comprising:
- a vessel;
- a thermally conductive foam placed within said vessel;
- a liquid mixture:
- said liquid mixture including a solvent and a solute having a known ratio;
- and
- said liquid mixture being in thermal contact with said thermally conductive foam;
- a heating element configured to heat said liquid mixture to a known temperature;
- a gas;
- and
- a vapor, said vapor also comprising said solvent and said solute;
- wherein, said vapor has a known concentration of said solute at equilibrium given said known temperature and;
- wherein said liquid and said vapor are in equilibrium.
9 more elements
A method of generating a vapor comprising:
- providing a vessel having a thermally conductive foam placed therein;
- placing a liquid mixture of a solvent and a solute in said vessel so as to at least partially submerge said foam in said liquid;
- heating said foam to generate a vapor from said liquid, said vapor also including said solvent and said solute and said vapor and said liquid being in equilibrium.
