Top 10 Take Aways for Air Sampling.
1.There are two principle means of monitoring the microbiological population of the air
• passive monitoring
• active sampling
2.Active monitoring requires the use of a microbiological air sampler to physically draw a known volume of air over,or through,a particle collection device.
3.The most important sources of contamination in any manufacturing operation are air,people,raw materials and water.
4.Passive monitoring is usually done using ‘settle plates’.
5.There are two types of active monitoring devices
• Impingers
• Impactors
6.It is essential that air samplers are properly validated and regularly calibrated to ensure accuracy.
7.The choice of sampling method is application dependent,according to ISO 14698-1,and must take into consideration:
• appropriate flow rate impact velocity
• collection accuracy and efficiency
• effect of the sampling method on the surrounding environment
8.Choice of monitoring locations should be based upon a documented risk assessment.
9.The flow rate of the sampler pump or fan should be properly calibrated and validated against a certified flow meter.
10.Airborne bacterial and fungal cells and spores may be present in droplets as “bio-aerosols”,as very small individual particles that stay suspended for long periods,or as larger clumps and aggregates that settle rapidly onto surfaces.

10大要点空气采样.
1.有原则的监测手段的微生物种群的空气
•被动监测
•主动采样
2.积极监测需要使用一个空气微生物采样器身体画一个已知的空气量,或通过,一个粒子收集装置.
3.最重要的污染源,在任何生产经营空气,人,原材料和水.
4.被动监测通常是使用的解决板”.
5.有2种主动监测装置
•撞击
6.至关重要的是,空气取样器是适当的验证和定期校准精度保证.
7.选择抽样方法是依赖于应用程序,根据14698-1,必须考虑到:
•适当的流量冲击速度
•采集精度和效率
•效果的采样方法对周围的环境
8.选择的监测地点应根据文件的风险评估.
9.流量的采样泵或风机应适当校准和验证认证的流量计.
10.空气中的细菌和真菌细胞和孢子可在液滴为“气溶胶”,非常小的个别颗粒悬浮在很长一段时间,或较大的团块和总量迅速沉降到表面.
