SKC采样器配件225-1

空气采样器系统包括探测器和采样网管。探测器由吸气泵、过滤器、激光探测腔、控制电路、显示电路等组成。吸气泵通过PVC管或钢管所组成的采样管网，从被保护区内连续采集空气样品放入探测器。空气样品经过过滤器组件滤去灰尘颗粒后进入探测腔，探测腔有一个稳定的激光光源。烟雾粒子使激光发生散射，散射光使高灵敏的光接收器产生信号。经过系统分析，完成光电转换。烟雾浓度值及其报警等级由显示器显示出来。主机通过继电器或通讯接口将电信号传送给火灾报警控制中心和集中显示装置。

空气采样器探测系统的探测原理是靠主机内部的抽气泵，透过延伸至探测区域的空气采样管路将空气样品抽回侦测室进行检测，当空气样品中检测物质的浓度达到一定程度时，系统即发出警报。

(Patented 5,904,752)。 Assessments of microbiological air quality are useful for studies of the airborne transmission of pathogens and of other biological particles in the air that may cause noninfectious diseases (such as allergy to pollen). The two principle methods of assessing microbiological air quality are passive monitoring and active sampling. Both methods were designed for studies of airborne bacteria or fungi. Passive monitoring is typically performed using settle plates, which are opened and exposed to the air for a given time, then incubated and resulting bacterial and fungal colonies are analyzed. Active sampling is performed with a microbiological air sampler that mechanically draws a known volume of air over, or through, a particle collection device. The particles are subsequently removed from the collection medium and analyzed. Air samplers are also used to collect airborne viruses, but it is difficult to do so primarily due to their small size and relatively low concentration in ambient air. Also, most of the available bioaerosol samplers are not suitable for the collection of viruses for reasons that include (a) they typically run for short periods of time (min), making it difficult to capture large volumes, (b) most do not separate particles by size, and (c), they are inefficient at collecting submicron particles
