作为一种新兴的采样仪器,无泵型采样器相比传统的空气采样泵,小巧便携,无需动力,佩戴时不影响劳动者的正常工作,因而特别适合长时间个体采样。又因为长时间个体采样的检测结果在推算职业卫生最重要的评估指标—时间加权平均接触浓度上有独特的优势,无泵型检测方法在职业卫生领域占据着越来越重要的地位。该文详细介绍了国内外无泵型采样器的发展历史,最新的研究进展和应用情况,介绍了无泵型采样器的工作原理,总结了管式及徽章式无泵型采样器的结构特点,分析了风速、湿度、温度等物理因素对无泵型采样器性能的影响,并对国内外关于无泵型采样器的研制和应用的相关标准和准则进行了总结,为未来无泵型采样器的设计和应用提出了新的思路。
As a new sampling instrument, the pumpless sampler is more compact and portable than the traditional air sampling pump, it does not need power and does not affect the normal work of the worker when worn, so it is especially suitable for long time individual sampling. In addition, the non-pump detection method occupies an increasingly important position in the field of occupational health because the detection results of individual samples for a long time have unique advantages in estimating the time-weighted average exposure concentration, the most important evaluation indicator of occupational health. This paper introduces the history of pump-free samplers at home and abroad, the latest research progress and application, introduces the working principle of pump-less samplers, summarizes the structural features of tube-type and badge-type pumpless samplers , Analyzed the influence of wind speed, humidity, temperature and other physical factors on the performance of the pumpless sampler, and summarized the relevant standards and guidelines for the development and application of the pumpless sampler both at home and abroad, The design and application of the device put forward a new idea.
