This online article summarises a number of different applications of the SciAps Hand Held LIBS analyser. In this result, 2 samples were used in the calibration, with a test time of about 4s. While undoubtedly a promotional piece, this gives some of the few available detection limit figures for handheld LIBS devices.

Be 10.0000 (Calibration Curve Slope) -10.0000 N/A Univariate 131.0000-500.0000 The samples were reasonably homogenized to approximately a 200 ┬Ám particle size or less, and were each about 50 g of soil. They were analyzed repeatedly in the same region, and also analyzed at three different regions within the soil bags.
