SKC气体采样泵为专业领域使用,因此说明书,或者使用沟通中有些术语比较生涩难懂,在此为广大用户进行系统解释,本章节主要说明采样的方式,下一章节解说读数。
主动采样
通过强制空气流动通过合适的收集媒体采样泵的空气污染物的收集。
Active Sampling
The collection of airborne contaminants by means of a forced movement of air by a sample pump through appropriate collection media.
被动采样
小空气采样器,收集空气中的气体或蒸气的无泵的使用。
Small air samplers or “badges” that collect airborne gases or vapors without the use of a pump. Chemicals diffuse through a diffusion barrier onto a sorbing medium inside the sampler at a fixed rate that can be scientifically determined.
吸附
气体和蒸汽等介质上的集合在吸附管吸附材料表面的集合。
封闭面采样
过滤器采用一二或三件盒中盒入口段采样和密封塞删除。
Closed-face Sampling
Filter sampling using a two or three-piece cassette with the cassette inlet section in place and the sealing plugs removed.
开面采样
滤波器采用一三块盒与盒口段切除,通常用于采样的石棉纤维和其他采样。
随机取样
直接收集空气污染物的混合物倒入装置如样品袋或检测管在一个短暂的时期。
Grab Sampling
The direct collection of an air-contaminant mixture into a device such as a sample bag or detector tube over a brief period.
采样套装
整个采样系统的采样介质(吸附管、过滤器、旋风、IOM、等)连接到软管样品泵。
The entire sampling system: sampling medium (sorbent tube, filter, cyclone, IOM, etc.) connected to a sample pump with flexible tubing.
综合抽样
空气污染物在较长时间内集合。
Integrated Sampling
The collection of air contaminants over an extended period.
低流量采样
空气中的污染物的采样(通常是气体和蒸汽)流量小于500毫升/分钟。
Low Flow Sampling
The sampling of airborne contaminants (typically gases and vapours) at flow rates less than 500 ml/min.
大流量采样
空气中的污染物的收集(典型的粒子)在流速大于1000毫升/分钟。
High Flow Sampling
The collection of airborne contaminants (typically particulates) at flow rates greater than 1000 ml/min.
空白样品
一个有代表性的采样介质作为控制与实际样品到实验室发。空白进行样品相同的程序,除了没有空气穿过他们。
Blank Sample
A representative sampling medium sent as a control with the actual sample to a laboratory. Blanks are subjected to the same procedures as samples, except no air is drawn through them.
