| Description | Analysis of soils is very important in environmental and agricultural chemistry. The conventional methods of soil preparation for inductively coupled plasma optical emission spectrometry (ICP-OES) are based on sample dissolution. However, decomposition of some samples is a very complicated and time-consuming procedure. Therefore, ICP spectrometry combined with laser ablation (LA) might be a solution for the analysis of resistant materials such as soils or other geological samples. Soil samples were presented for the analysis as cast pellets with epoxide resin binder. Q-switched Nd:YAG laser operated at the wavelengths of 1064 nm and 266 nm and repetition rate of 10 Hz was used for ablation of prepared pellets. Samples were placed into an ablation cell which was connected with XY-translator allowing a sample moving during ablation. The ablated material was transported by Ar along a polyamide tubing to ICP spectrometer Jobin Yvon 170 Ultrace (laterally viewed). The analytical response for soil pellets were used to produce the signal vs. element content plots using 1064 nm and 266 nm laser wavelenght. |
