SKC階梯式個人采樣器
美國SKC五級個人采樣器sioutas通過撞擊和分離空氣中顆粒，把顆粒分為：＞2.5um,1.0-2.5um,0.50-1.0um,0.25-0.5um和＜0.25um,當(dāng)使用PTFE過濾器，sioutas沖擊器是高效收集顆粒不影響油脂或底涂層的使用，保留大小分級不穩(wěn)定化合物的化學(xué)分析。
SKC階梯式個人采樣器性能參數(shù)：
一、精確顆粒分離：
Precise particle separation
1、顆粒切割點“2.5um,1.0um,0.50um和0.25um
1particle size cut-points:2.5um,1.0um,0.50um,and 0.25um
2、采集同時，把有效樣本分成粗，細，超細顆粒。
2The only personal impactor that efficiendy samples coarse,fine,and ultrafine particles simultancously
3、即使在高濃度顆粒的情況下也能保持高的收集效率
3Maintains high collection efficiency even at high particle concentrations.
二、優(yōu)化l流速9L/Min。降低24小時采樣壓力。
Optimized at a 9L/min flow rate with low pressure drop for 24-hour sampling
1提高了分析的靈敏度。
improves analytical sensitivity。
2zui大限度減少非檢測樣品的影響。
minimizes non-detectable samples.
三、保留不穩(wěn)定化合物。
Preserves unstable compounds
1化學(xué)惰性收集基板。
Chemically inert collection substrate
2油脂樣品不堵塞污染。
No impaction grease to contaminate sample
四、減少粒子反彈和損失
minimal particle bounce and internal wall losses.
五、適用于室內(nèi)外采樣
suitable for indoor and outdoor sampling
六、粒子分級樣品可以用化學(xué)和微觀分析。
size-fractionated samples can be analyzed gravimetrically,chemically,and microscopically
七、體積小，重量輕
small and lightweight
八、適合個人和區(qū)域采樣。
suitable for personal or area sampling
