SKC階梯式個(gè)人采樣器

美國(guó)SKC五級(jí)個(gè)人采樣器sioutas通過(guò)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(guò)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(jí)不穩(wěn)定化合物的化學(xué)分析。

SKC階梯式個(gè)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(diǎn)“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(shí)，把有效樣本分成粗，細(xì)，超細(xì)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(shí)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。
