LIBS is applied to the detection of Hg and I in gases at low pressure in air and pure N2 using nanosecond and 35ps pulse length lasers. The authors experimented with different gas pressures, with low pressure providing the best detection limits. The effect of laser power and gate delay were also investigated.
