The analysis of polymers by secondary ion mass spectrometry (SIMS) has been a topic of interest for many years. In recent years. the primary ion species evolved from heavy monatomic ions to cluster and massive cluster primary ions in order to preserve a maximum of organic information. The progress in less-damaging sputtering goes along with a loss in lateral resolution for 2D and 3D i... https://herbsdailyes.shop/product-category/face-creams/
