SKC氣體采樣泵為專業(yè)領域使用，因此說明書，或者使用溝通中有些術語比較生澀難懂，在此為廣大用戶進行系統(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短暫的時期。

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

整個采樣系統(tǒng)的采樣介質（吸附管、過濾器、旋風、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間內集合。

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

一個有代表性的采樣介質作為控制與實際樣品到實驗室發(fā)?？瞻走M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.
