“…Laser energy profile has been reported as responsible for ablation crater structure [31][32][33]. However, other parameters should be taken into account, e.g., viscosity of melt, wettability melt-solid, melt mobility, and surface tension of the melt that is influenced by the gas environment, too.…”

“…135 A time lag between laser firing and signal detection occurs during which the laser might move forward, which needs to be considered when linking line-scan signals to specific locations on a sample. 136 Plotnikov et al 137 developed a mathematical model for establishing the correlation between spatial and temporal coordinates of the analytical signal from line scans correctly. The model is based on the estimation of the signal delay caused by material washout as an effect of the size of the laser ablation chamber.…”

The creation of chemical images as 2- and 3-dimensional representations of the elemental and isotopic distributions in physical and biological structures has gained significant importance for the spatially distinct analysis and interpretation of analytical data. As the principle of ‘chemical imaging’ can be applied across multiple scales combining multiple information levels and multiple commodities, e.g. by combining the information from single cells to higher hierarchical levels, like a complete animal, or by linking single compartments or plant and animal species to landscape information (‘isoscapes’), it is increasingly applied in a wide field of scientific disciplines. This chapter introduces secondary ion mass spectrometry (SIMS) and laser ablation inductively coupled plasma sector field mass spectrometry (LA-ICP-SFMS) as sensitive surface analytical techniques capable of performing direct solid analysis at the micrometre down to the nanometre scale for the production of high-resolution chemical images. The basic analytical background and key elements in the image creation process using SIMS and LA-ICP-MS are described. Software tools supporting data reduction and image production together with selected examples of chemical pictures and case studies are also given.

“…A number of studies have attempted to produce generalised approaches to this phenomenon. For example, Plotnikov et al (2002) applied mathematical post-processing of laser ablation data to deconvolve the complexity of the analytical response, while Sanborn and Telmer (2003) provided a practical method for the assessment of spatial resolution in line scans. The extent of this problem, however, is controlled very strongly by ablation cell design and thus considerable effort has been expended in both commercial and research organisations to design systems for "rapid washout".…”

Laser ablation ICP‐MS represents a promising new development for the acquisition of elemental and isotopic images from a variety of different materials. Compared to existing methods for imaging, it offers relatively rapid throughput, very wide dynamic range, a relatively clean mass spectrum, utility at a variety of scales (from μm to cm) and multi‐element/isotopic capability. Although developing rapidly in the biological sciences, the method has not yet seen widespread application to geological materials. This contribution documents some preliminary experiments aimed at understanding the fundamental aspects of elemental and isotopic image acquisition using laser ablation ICP‐MS. In particular, we note that ablation cell designs must be optimised to promote rapid system response, in contrast to the signal‐smoothing that is often preferred for simple spot analyses. Furthermore, experimental parameters must be carefully evaluated on a system‐by‐system basis to avoid the blurring effects of re‐sampling phenomena. With careful attention to these details, and development of appropriate data processing software, laser ablation ICP‐MS imaging has much to offer workers in the Earth and environmental sciences.
