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(yǔ)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(dòng)采樣
通過強(qiáng)制空氣流動(dòng)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(dòng)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(cè)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(zhǎng)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)??瞻走M(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.
