SKC氣體采樣泵為專業(yè)領(lǐng)域使用，因此說明書，或者使用溝通中有些術(shù)語比較生澀難懂，在此為廣大用戶進(jìn)行系統(tǒng)解釋，本章節(jié)主要說明采樣的方式，下一章節(jié)解說讀數(shù)。

主動采樣

通過強(qiáng)制空氣流動通過合適的收集媒體采樣泵的空氣污染物的收集。

Active Sampling

The collection of airborne contaminants by means of a forced movement of air by a sample pump through appropriate collection media.

被動采樣

小空氣采樣器，收集空氣中的氣體或蒸氣的無泵的使用。

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

氣體和蒸汽等介質(zhì)上的集合在吸附管吸附材料表面的集合。

封閉面采樣

過濾器采用一二或三件盒中盒入口段采樣和密封塞刪除。

Closed-face Sampling

Filter sampling using a two or three-piece cassette with the cassette inlet section in place and the sealing plugs removed.

開面采樣

濾波器采用一三塊盒與盒口段切除，通常用于采樣的石棉纖維和其他采樣。

隨機(jī)取樣

直接收集空氣污染物的混合物倒入裝置如樣品袋或檢測管在一個(gè)短暫的時(shí)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.

采樣套裝

整個(gè)采樣系統(tǒng)的采樣介質(zhì)（吸附管、過濾器、旋風(fēng)、IOM、等）連接到軟管樣品泵。

The entire sampling system: sampling medium (sorbent tube, filter, cyclone, IOM, etc.) connected to a sample pump with flexible tubing.

綜合抽樣

空氣污染物在較長時(shí)間內(nèi)集合。

Integrated Sampling

The collection of air contaminants over an extended period.

低流量采樣

空氣中的污染物的采樣（通常是氣體和蒸汽）流量小于500毫升/分鐘。

Low Flow Sampling

The sampling of airborne contaminants (typically gases and vapours) at flow rates less than 500 ml/min.

大流量采樣

空氣中的污染物的收集（典型的粒子）在流速大于1000毫升/分鐘。

High Flow Sampling

The collection of airborne contaminants (typically particulates) at flow rates greater than 1000 ml/min.

空白樣品

一個(gè)有代表性的采樣介質(zhì)作為控制與實(shí)際樣品到實(shí)驗(yàn)室發(fā)。空白進(jìn)行樣品相同的程序，除了沒有空氣穿過他們。

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.
