|A special interaction chamber was designed to be compatible with the New Wave UP MACRO Laser Ablation System and to fulfill all demands for simultaneous measurements double pulse laser-induced breakdown spectroscopy (DP-LIBS) and laser ablation coupled to ICP optical emission or mass spectrometry. For single pulse LIBS only two orthogonal fused silica windows are used, the first from the top for the ablation laser beam and the second one from the front for collecting the light of plasma. For DP-LIBS the third window from the side is needed being orthogonal to the previous two. For Laser ablation ICP OES/MS a flow of transporting gas has to be implemented. The inner space of the chamber was optimized for low volume and quick flush of gas, which is crucial for the method. The gas enters the chamber through three oblique jets on the top and leaves to the ICP on the back side. The chamber is equipped with a vertically adjustable sample holder to adapt various sample heights and exchangeable inner rings allowing to various sample diameters to be altered and to minimize the inner volume.
