納米顆粒氣溶膠發生器

Palas公司提供的納米氣溶膠發生器按照客戶的需求，分為以下型號：
DSP3000
DSP3000是將選定的可燃氣體的引燃生成煙灰氣溶膠。DSP3000和DSP3000H均可以按要求調整空氣與可燃氣體比例來調節顆粒粒徑和煙灰氣溶膠流量。在電腦或筆記本上提供的軟件可以快速并且再現性的完成操作參數的設置。伴隨達3g/h的煙灰流量，DSP3000是完美滿足柴油機煙灰顆粒過濾器（DPF）過濾效率測試的*。DSP3000和DSP3000H均可大值為300mbar的正向壓力下正常工作。

GFG3000
用來產生測試或校準氣溶膠的氣溶膠發生器必須在粒徑分布，濃度等參數保持穩定，并且可重復進行參數調整并保持再現性。GFG1000和GFG3000電花發生器可以從純凈石墨中生產具備可調整的粒徑分布、類似于柴油機煙灰的測試氣溶膠，粒徑范圍20nm-150nm.，并且大約6mg/h低流量及高再現性。GFG3000內置的流量控制器可以對氬氣和稀釋氣體進行更精確的流量調整。其他用于顆粒生產的材料包括銅（Cu),金（Au),銀（Ag)等。
氣溶膠發生器是在氬氣氣氛內通過兩個加載高電壓的石墨電極用來生成一個跳躍電花，這也是為什么GFG3000氣溶膠發生器也被稱作“電花發生器"。
