To improve detection limits for elements such as Hg, As, Sb, Se and Sn, one can use hydride generation. This is particularly useful for environmental analysis, where the concentration ranges are close to the g/L level. One of the main drawbacks of this technique, until recently, has been the requirement of performing the analysis
twice: once for the normal elements and the other for the hydride species. Additionally, it was necessary to replace the standard spray chamber system with a hydride generator device. With the
CMA, it is not necessary to change anything.
Using the same conditions and cassette, all the normal elements and hydride species can be determined in one analysis run and the detection limits are improved by a factor of 5 to 50 for the hydride forming elements.
