Reactor, test apparatus, and test method
Disclosed herein are a reactor, a test apparatus, and a test method, which measure, when a material included in a sample acts as an interfering material with respect to estimating a concentration of a target material, a concentration of the interfering material, and correct an estimated concentration of the target material based on the concentration of the interfering material, thereby improving the reliability and accuracy of the concentration of the target material. The reactor includes: a target material detecting chamber in which a first reagent that includes a first material that is activated by a target material is contained; a first material detecting chamber in which a second reagent that includes the target material is contained; an inlet hole into which a sample is injected; and a channel configured to connect the inlet hole, the target material detecting chamber, and the first material detecting chamber to each other.
1. A test apparatus for measuring a concentration of a target material included in a sample, comprising:
a detector comprising a light emitter and a light receiver; and
a controller programmed to measure a concentration of the target material,
wherein the controller is programmed to control the light emitter to radiate light of a first predetermined wavelength to a target material detecting chamber containing a first reagent that includes a first material that is activated by the target material, and a first material detecting chamber containing a second reagent that includes the target material, and to control the light receiver to detect light that has propagated through or been reflected from the target material detecting chamber and the first material detecting chamber, and
wherein the controller is further programmed to measure a concentration of the first material based on at least one output signal provided by the detector, and to adjust the measurement of the concentration of the target material based on the measured concentration of the first material.
2. The test apparatus according to claim 1 , further comprising a storage configured to store a factor that corresponds to a degree of influence by which the concentration of the first material included in the sample influences the measurement of the concentration of the target material.
3. The test apparatus according to claim 1 , wherein the controller is further programmed to measure the concentration of the target material based on a first output signal provided by the detector with respect to the target material detecting chamber, and to measure the concentration of the first material based on a second output signal provided by the detector with respect to the first material detecting chamber.
4. The test apparatus according to claim 2 , wherein the factor includes a negative sign or a positive sign, and
the controller is further programmed to adjust the measurement of the concentration of the target material by adding a value obtained by applying the factor to the measured concentration of the first material to the measured concentration of the target material.
5. The test apparatus according to claim 1 , wherein each of the first reagent and the second reagent further includes a second material that is configured for activating the first material, and
the detector is further programmed to radiate light of a second predetermined wavelength to a second material detecting chamber containing a third reagent that includes the target material and the first material, and to detect light that has propagated through or been reflected from the second material detecting chamber.
6. The test apparatus according to claim 5 , wherein the controller is further programmed to measure a concentration of the second material based on a third output signal provided by the detector with respect to the second material detecting chamber.
7. The test apparatus according to claim 6 , wherein the controller is further programmed to adjust the measurement of the concentration of the target material based on the measured concentration of the first material and the measured concentration of the second material.
8. The test apparatus according to claim 7 , further comprising a storage configured to store a first factor that corresponds to a first degree of influence by which the concentration of the first material included in the sample influences the measured concentration of the target material, and a second factor that corresponds to a second degree of influence by which the concentration of the second material influences the measured concentration of the target material.
9. The test apparatus according to claim 8 , wherein each of the first factor and the second factor has a negative sign or a positive sign, and
the controller is further programmed to adjust the measurement of the concentration of the target material by adding a first value obtained by applying the first factor to the measured concentration of the first material and a second value obtained by applying the second factor to the measured concentration of the second material to the measured concentration of the target material.
