Abstract
Provided are an apparatus for measuring an ionic mobility of a harmful material and a reference data obtaining method thereof. The method includes obtaining a measurement signal by detecting a charge of an ion between electrodes, obtaining a noise signal by insulating the electrodes from the ion, aligning the noise signal with the measurement signal, removing a part of the measurement signal aligned with the noise signal, and calculating reference data from a remaining part of the measurement signal.
Claims11
A reference data obtaining method for an ionic mobility measuring apparatus, comprising:
- obtaining a measurement signal by detecting a charge of an ion between electrodes;
- obtaining a noise signal by insulating the electrodes from the ion;
- aligning the noise signal with the measurement signal;
- removing a part of the measurement signal aligned with the noise signal;
- and
- calculating reference data from a remaining part of the measurement signal.
An apparatus for measuring an ionic mobility of a harmful material, comprising:
- a chamber filled with a harmful material;
- a plurality of electrodes disposed in the chamber;
- a laser configured to irradiate a laser beam to the harmful material between the electrodes;
- a detector connected to the electrodes and detecting an ion of the harmful material ionized by the laser beam;
- and
- an ion filter disposed between the electrodes and insulating the ion from the electrodes so that the detector detects a noise of the ion through the ion filter.
