纯净的单矿物样品是化学分析和测定各项物理参数、化学性质,光学常数所必不可少的.但是提纯一个单矿物样品不是一件容易的事,常常因为某些性质相近而使共生、伴生矿物不易分开,或者即使分开,也常因有杂质而达不到目的.最后的办法是双目镜下进行手选:这是一件费时费事的工作,为缩短手选时间,笔者设计了一个简单的工具——单矿物吸取针。经长期使用证明,效果良好,使用方便,效率颇高. 1.原理利用洗瓶打气球排气后的球内负压,将针端的目的矿物吸入储藏管,从而挑出目的矿物。
Pure single mineral samples are essential for chemical analysis and determination of various physical parameters, chemical properties, and optical constants, but it is not easy to purify a single mineral sample, often because some properties are similar Mineral is not easy to separate, or even if separate, often due to impurities and can not achieve the purpose of the final approach is binocular hand selection: This is a time-consuming work, to shorten the hand timing, I designed a Simple tool - single mineral needle. Proven by long-term use, the effect is good, easy to use, high efficiency 1. Principle The use of bottle after playing balloon exhaust negative pressure within the ball, the needle end of the target mineral into the storage tube to pick out the purpose of minerals.
