Gas component collector, gas component collecting device, filter producing method, and gas component analyzing apparatus

A gas component collecting device which collects at least one gas component to be analyzed, comprising:

• a gas introducing section that introduces gas, a gas component collector that selectively collects the to-be-analyzed at least one gas component contained in the gas,
• a first pipe that connects between the gas introducing section and the via a first pipe, and
• a second pipe that allows the introduced gas to be discharged out of the gas component collecting device,
• wherein the gas component collector comprises:
• a filter comprising an adsorbent and an adsorbent holding plate having a first face, a second face and a plurality of holes that are formed by boring through from the first face to the second face and are filled with the adsorbent adsorbing at least one gas component to be analyzed, the filter for which both (AL−V)2/L3≧0.003 mm3 and V/AL ≧0.3 apply, where V is a total volume of the adsorbent, A is a sum of opening areas of the holes, and L is an average length of the holes;
• and
• a holding container housing the filter having a first face side on which a first opening portion connected to the first pipe is formed and a second face side on which a second opening portion connected to the second pipe is formed,
• wherein the gas component collector is detachably installed at the first opening portion and second opening portion in the gas component collecting device.

A gas component analyzing apparatus which analyzes at least one gas component of interest, comprising:

• a gas component collector that has collected the at least one gas component of interest;
• a heater that heats the gas component collector;
• an analyzer that connects to the gas component collector and analyzes the at least one gas component of interest;
• and
• a carrier gas introducing section that introduces into the gas component collector a carrier gas to send a desorbed at least one gas component of interest from the gas component collector to the analyzer,
• wherein the gas component collector comprises:
• a filter comprising an adsorbent and an adsorbent holding plate having a first face, a second face and a plurality of holes that are formed by boring through from the first face to the second face and are filled with the adsorbent adsorbing at least one gas component to be analyzed, the filter for which both (AL−V)2/L3≧0.003 mm3 and V/AL ≧0.3 apply, where V is a total volume of the adsorbent, A is a sum of opening areas of the holes, and L is an average length of the holes;
• and
• a holding container that houses the filter, the holding container having a first face side and a second face side, on at least one of which a first opening portion for introducing gas and a second opening portion for allowing the introduced gas to be discharged are formed,
• wherein the gas component collector is detachably installed at the first opening portion and second opening portion in the gas component analyzing apparatus.
