一种新型的HF发生器

A New Type of Hydrogen Fluoride Generator.

江苏省植物研究所在HF发生技术上实现了技术突破,于1989年研制了一种新型的HF发生器。其基本原理是将一定浓度的HF溶液通过高温瞬吋完全气化,再与空气混合形成所需浓度的HF供试气体。该发生器的特点是它与开顶式熏气装置相配套使用时,能提供浓度稳定的HF气体,对温度变化的波动性小,仪器响应性能好和技术设计灵活。本文旨在介绍这种发生器的基本原理,组成结构,性能特点和应用前景。

Reported in this paper is a new type of HF generator which has been developed in Jiangsu Institute of Botany in 1989. The process of producing HF is substantially improved in the generator, so that HF solution of a specified concentration can be vaporized at a high temperature to form HF gas of a desirable concentration. The generator is suitably applied to the field experiments with the open-top chamber.
