Outstanding LA-ICP-MS

Cell Performance Metrics

Both the M50 and S155 sample cells are based on an advanced dual-volume design, which provides a number of key benefits. Both cells were designed and assembled by Laurin Technic (director Michael Shelley, a pioneer in LA-ICP-MS development) and these cells offer a number of high-performance advantages over other commercial cell designs.

Excellent Signal Homogeneity

Some sample cells show marked signal variation across their movement range. The dual-volume design of the M50 and S155, however, ensures that the ablation plume is subjected to the same gas flow regardless of the physical location within the cell. The published results shown here highlight the total lack of variation between the four corners of the cell.

Excellent Signal Uniformity

For line scanning and mapping, it is important that the scan direction does not affect the signal sensitivity. Both the M50 and S155 have been carefully designed to avoid any interference between the stage movement and the collection efficiency. Furthermore, stages and software control have been rigorously tested to ensure zero stage hesitation at waypoints or corners.

Fast Washout Times

For line scans, mapping, and depth profiling, fast washout times are essential. For point analysis, a fast washout time can allow faster throughput, better identification of sample heterogeneity (nuggets, inclusions, etc.), and shorter analysis times. The washout time is determined by timing how long it takes signals to reduce to background levels.

Controllable Smoothing

Not all applications require a fast washout time, and in these cases it is very important to apply some kind of smoothing to the signal. Historically, smoothing devices have been problematic, but "The Squid" overcomes these limitations and provides just the right amount of smoothing for ablation at low laser repetition rates.

While some of these published results are from the M50, pre-press results for the S155 show similar performance.
