Laser ablation technology is a widely recognized solid direct injection chemical analysis technique. In most cases, no sample preparation is required, and any solid sample can be analyzed for elemental and isotopic content within a few minutes. There are two main methods for detecting erosion quality: measuring the photons emitted by the surface light induced plasma of the sample, or introducing the eroded aerosol into the airflow and transporting it to a secondary light source. Laser-induced breakdown spectroscopy（LIBS is based on measuring the emitted light in plasma.inductively coupled plasmaMass spectrometry（ICP-MS or inductively coupled plasma optical emission spectroscopy (ICP-OES) methods are based on the transport of eroded aerosols.
