Abstract: A novel device, method and systems disclosed managing the thermal challenges of LIBS laser components and a spectrometer in a handheld structure as well the use of simplified light signal collection which includes a bare fiber optic to collect the emitted light in close proximity to (or in contact with) the test material. In one example embodiment of the handheld LIBS device, a burst pulse frequency is 4 kHz is used resulting in a time between pulses of about 250 μs which is a factor of 10 above that of other devices in the prior art. In a related embodiment, an active Q-switched laser module is used along with a compact spectrometer module using a transmission grating to improve LIBS measurement while substantially reducing the size of the handheld analyzer.

Abstract: A system and a method is described herein for the collection of small particles in a concentrated manner, whereby particles are deposited onto a solid surface or collected into a volume of liquid. The collected samples readily interface to any of a number of different elemental, chemical, or biological or other analysis techniques.
