Passive type emission flux sampler and flux measuring apparatus

A passive type emission flux sampler for measuring an emission flux of a specified chemical sample released from an inspection object, comprising:

• a hollow casing comprising an inner surface and a bottom surface opposite the inner surface in which an opening is formed for taking in a chemical substance released from the inspection object;
• and
• an adhesive layer formed at a periphery of the opening and configured to bond the bottom surface to a surface of the inspection object,
• wherein the inner surface is configured to receive a test specimen that changes color in a reaction with the chemical substance.

A measuring apparatus for measuring emission flux of a passive type flux sampler, comprising:

• a hollow casing comprising an inner surface having a transparent observing section and a bottom surface opposite the inner surface in which an opening is formed for taking in a chemical substance released from an inspection object, and an adhesive layer formed at a periphery of the opening and configured to bond the bottom surface to a surface of the inspection object, wherein the inner surface is configured to receive a test specimen that changes color in a reaction with the chemical substance,
• a light shielding chamber formed with a setting stage for positioning the flux sampler for a predetermined time;
• a light source provided to the light shielding chamber for irradiating a measuring light to the test specimen through at least one of the opening and the observing section,
• an optical sensor configured to detect the intensity of a reflection light from the test specimen, and
• a calculation processor configured to calculate the emission flux based on the intensity of reflection light detected by the optical sensor.
