DST-1000 PFA亚沸蒸馏器

简介：详细介绍了savillex的最新产品DST-1000亚沸蒸馏器的结构，原理，功能和用途，以及使用的方法，该产品可用于高纯度酸（盐酸，硝酸，硫酸，氢氟酸，高氯酸等）纯水，的再次提纯，以提高高灵敏度分析仪器对本底的要求，各种元素的含量均小于ppt水平

飞行时间二次离子质谱仪介绍

简介：The Millbrook MiniSIMS is the only instrument to provide a fast, comprehensive surface analysis capability in a convenient desktop size. Millbrook have now introduced a second, high-performance, version of the MiniSIMS incorporating a time of flight mass spectrometer (ToFSIMS).

医用PTFE材料表面改性研究

简介：医用PTFE材料有非常好的机械性能，但是材料的亲水性并不是非常理想，通过Ar， NH3，O2， N2等各种气体等离子表面改性可以提高材料亲水性。本文通过对各种条件改性后材料随时间变化其亲水性变化以及材料表面化学成分变化的研究，为医用材料表面改性条件的选择提出理论依据。

材料表面改性的快速鉴定

简介：The development of a novel bench top SIMS instrument (Millbrook MiniSIMS) has brought routine SIMS analysis to many new users, for example museum conservators. This is a result of the simple operation and the relatively low capital cost of the instrument. We report here on the continued development of the system in terms of increasing performance and functionality and its use in museum conservation based applications where a mobile instrument for high throughput, rapid SIMS analysis has proven to be of great benefit to the user. The example we describe here is the application of the MiniSIMS to the analysis of silver thread woven into a silk dress before and after laser cleaning.

直接进样高效雾化器

简介：本文介绍了MEINHARD公司直接进样高效雾化器，该类型雾化器可以将GC，LC以及其他一些微量、生化、贵重样品通过直接注入ICP、ICP-MS进行分析，由于管路的死体积很小，几乎所有样品都可以进入等离子体炬进行分析，大大减低了样品用量，提高了检出限。
