1. An adsorption system comprising:
adsorbent particles that adsorb a component contained in a gas;
a container containing the adsorbent particles;
a channel defining a flow path which is inserted into the container, the channel having a distal tip with an opening formed thereon, the opening having a size which is larger than a particle diameter of the adsorbent particles; and
a pump configured to induce a flow of gas from the container into the opening and through the channel along a length of the channel,
wherein the container includes a tapered bottom surface portion that is formed to approach the opening towards a center of the container, and
a portion of the adsorbent particles are located within the distal tip of the channel and extend into the channel a length that is more than half the length of the channel,
wherein the channel is configured such that gas passing through the channel passes through the opening.
