Particle into Liquid Sampler (PILS)

Model 4001


The PILS is one of the simplest methods available to acquire samples for aerosol chemistry applications. It can be easily integrated with the analytical method of your choice. Ion chromatography systems and total organic analyzers are routinely used with the PILS. These analytical methods allow on-line analyses of aerosol chemistry for major water soluble ions and organic species.

Brechtel also offers a vial collection system to deliver liquid sample to vials if you don’t want to bring your aerosol chemistry lab to the field. The vial collection also lets you set your sample time resolution based on your research needs and not based on the speed of your analytical method.

  • PM1 or PM2.5 bulk aerosol sampling
  • Fully characterized and field tested
  • Vial collection with multiple vial sizes using optional Auto-collector
  • Rack mount tabs fits standard 19 inch racks
  • Software to record PILS temperatures and control optional auto-collector


  • Low maintenance
  • Easy to operate and install with compact size
  • Continuous unattended long-term operation
  • Multiple analytical techniques possible

  • The user interface/software made the use and operation of the PILS particularly straightforward; it is among the best equipment-user interfaces that I have used.
