Laser induced breakdown spectroscope analyzing aerosol

A laser induced breakdown spectroscopy (LIBS) device comprising:

• a LIBS module;
• and
• a pipe,
• wherein the LIBS module includes:
• a cover having a first optical channel through which a laser beam passes and a second optical channel through which plasma emission light passes therein,
• a first optical system placed in the first optical channel, and
• a second optical system placed in the second optical channel,
• wherein a clamp with a coupling hole through which the pipe passes is formed in the cover,
• wherein the coupling hole is placed in a region where an extension path of the first optical channel and an extension path of the second optical channel cross,
• wherein the pipe is coupled to the LIBS module by penetrating the coupling hole,
• wherein a first opening and a second opening are formed in a first segment of the pipe,
• wherein the first optical system includes a first window member placed on one end of the first optical channel,
• wherein the second optical system includes a second window member placed on one end of the second optical channel,
• wherein, while the first segment of the pipe is coupled to the coupling hole, the first window member is placed at a location aligned with the first opening, and
• wherein, while the first segment of the pipe is coupled to the coupling hole, the second window member is placed at a location aligned with the second opening.
