Abstract (en)

An ablation cell for laser ablation of a sample material comprises a sample chamber (21) for housing a sample. A carrier gas (G1) is fed to the sample chamber. A laser beam (41) impinges on a sample (23) in the sample chamber. The carrier gas together with ablated aerosol is removed from the sample chamber (21) through an outlet channel (12). In order to reduce dispersion of the ablated aerosol, a make-up gas (G2) is fed to the outlet channel through at least one make-up gas channel. The make-up gas channel merges with the outlet channel at a channel junction (17). The make-up gas channel either concentrically surrounds the outlet channel at the channel junction (17), or at least two make-up gas channels (14, 15) are provided, the make-up gas channels merging symmetrically into the outlet channel.
