我系研究了激光全蒸发固体进样-ICP系统,首次采用连续激光蒸发固体物质进行分析,比较了连续激光和脉冲激光蒸发固体物质的异同点。针对连续激光的特点,提出了“激光全蒸发” 的新概念,设计出“激光全蒸发-ICP” 系统,并对该系统进行了优化,取得了非常满意的效果。 1.配合该系统的需要,设计出千斤顶直压式压片机,使制备几毫克的小样片成为可能,改善了制样条件,样品制备简单快速。 I studied the laser evaporative solid injection-ICP system, the first time using continuous laser evaporation of solid material for analysis, compared the continuous laser and pulsed laser evaporation of solid substances similarities and differences. According to the characteristics of continuous laser, a new concept of “laser evaporation” was proposed. The “laser evaporating-ICP” system was designed and the system was optimized. Satisfactory results were achieved. 1. With the needs of the system, designed jack pressure tableting machine, the preparation of a few milligrams of small samples possible to improve the sample preparation conditions, the sample preparation is simple and fast.
