Local high schools, CVTC team to lessen college cost

Eau Claire North High School seniors Katie Schemenauer, left, and lab partner Jaren Peplinski work on a project in a Biotechnology class in which they test soy flour for the presence of DNA from other sources. The class not only counts toward their high school graduation but also earns for them credit from Chippewa Valley Technical College, which can be transferred to area universities.

Laser Induced Breakdown SpectrometerBackground:

Laser Induced Breakdown Spectroscopy (LIBS) utilizesan infrared laser to ablate a sample and create a plasmafield. This plasma emits a unique spectrum of light that is representative of the chemical makeup of the sample.One way to achieve laser ablation is with the use of a CO2 laser. These lasers create a beam in the infrared lightwith a wavelength between 9.4 and 10.6 micrometers. This radiation is absorbed by covalent bonds within the Sample, causing an increase in vibrational motion, andTherefore an increase in heat. This excitation causes a change in phase of the material, as well as causing electronic excitation in the molecules. When the excitedelectrons return to a ground state, they emitcharacteristic wavelengths of light. CO2 lasers use a Mixture of 9.5% CO2, 13.5% N2, and 77% He for lasing. The CO2, and N2 are excited by collision with electrons, And emit a photon in the IR range. The excess energy in These molecules is then transferred to He atoms, which Carry the excess energy to the surface of the glass tube.

The Build:

The first part of the LIBS system that needed to beconstructed was a flow through CO2 laser. This laserwas constructed from plumbing fittings, and a glass tube from a neon sign. The fittings were machined ina lathe to ensure proper geometry, then cleaned. Holeswere drilled through PVC pipe to create a mounting system for the laser parts, and wooden pegs were madeto hold the PVC mounts in the proper place. The partswere aligned so that a laser beam could be passed down the center of the laser before being secured in place. A first surface mirror was obtained from an oldprojection TV, and an NaCl lens was ordered from anonline optics supplier. A power supply was obtained that can provide between 7kV and 9kV to the laser, andwas wired to the electrodes. The gas and vacuum lineswere added to the laser, and then all the joints were sealed with epoxy. Cooling lines were then wound around the glass tube and secured. Final adjustment ofthe laser will be made by adjusting the tension of the focusing bolts located on the end flanges of the laser.
