Device and method for quantitative evaluation of deodorant performance

An apparatus for quantitatively evaluating performance of a deodorant member, comprising:

• a vaporization module configured to vaporize an ammonia water;
• an adsorption/desorption module connected to the vaporization module, and configured to adsorb and desorb the vaporized ammonia on a surface of the deodorant member;
• and
• a collection module connected to the adsorption/desorption module, and configured to collect the desorbed ammonia gas,
• wherein the adsorption/desorption module comprises a reactor, the deodorant member accommodated in the reactor, a tubular kiln adapted to heat the reactor, and a by-pass adapted to inject a carrier gas into the reactor, and
• the deodorant member comprises a deodorant agent-containing superabsorbent polymer (SAP) or a mixture of a deodorant agent and a superabsorbent polymer,
• wherein the vaporization module comprises a syringe pump;
• a first stainless tube connected to a syringe tip of the syringe pump;
• a second stainless tube having a stainless line inserted therein;
• a heating band surrounding the second stainless tube;
• and a gas injection unit for injecting the carrier gas into the second stainless tube.
