SKC阶梯式个人采样器
美国SKC五级个人采样器sioutas通过撞击和分离空气中颗粒，把颗粒分为：＞2.5um,1.0-2.5um,0.50-1.0um,0.25-0.5um和＜0.25um,当使用PTFE过滤器，sioutas冲击器是高效收集颗粒不影响油脂或底涂层的使用，保留大小分级不稳定化合物的化学分析。
SKC阶梯式个人采样器性能参数：
一、精确颗粒分离：
Precise particle separation
1、颗粒切割点“2.5um,1.0um,0.50um和0.25um
1particle size cut-points:2.5um,1.0um,0.50um,and 0.25um
2、采集同时，把有效样本分成粗，细，超细颗粒。
2The only personal impactor that efficiendy samples coarse,fine,and ultrafine particles simultancously
3、即使在高浓度颗粒的情况下也能保持高的收集效率
3Maintains high collection efficiency even at high particle concentrations.
二、优化l流速9L/Min。降低24小时采样压力。
Optimized at a 9L/min flow rate with low pressure drop for 24-hour sampling
1提高了分析的灵敏度。
improves analytical sensitivity。
2zui大限度减少非检测样品的影响。
minimizes non-detectable samples.
三、保留不稳定化合物。
Preserves unstable compounds
1化学惰性收集基板。
Chemically inert collection substrate
2油脂样品不堵塞污染。
No impaction grease to contaminate sample
四、减少粒子反弹和损失
minimal particle bounce and internal wall losses.
五、适用于室内外采样
suitable for indoor and outdoor sampling
六、粒子分级样品可以用化学和微观分析。
size-fractionated samples can be analyzed gravimetrically,chemically,and microscopically
七、体积小，重量轻
small and lightweight
八、适合个人和区域采样。
suitable for personal or area sampling
