All the sampling heads are designed for use with a controlled rate of air provided via a personal air sampling pump. Sampling media (filters) are placed inside the heads directly or using cassettes. The filter will be weighed before sampling and then again afterwards to gravimetrically determine the amount of dust collected. Inhalable sample heads collect a particle size of 100 micron and smaller. See more
Respirable fraction sampling heads are specifically designed to separate out the smaller dust fractions which travel further into the human airways and are generally more harmful. The collection efficiency curve meets the ACGIH/ISO/CEN standards for a respirable curve with a median 50% cut point of 4micron.
The cyclones work by physical separation of particles, whilst the conical inhalable head operates by utilising size selective foams which can also give other PM fractions of particulates. See more
Other Sampling Heads
We also supply other sampling heads designed for specific applications, for example; a Swinnex head for Rosin/Welding fumes or a filter head for lead sampling. See more
Diffusive or Passive Samplers are also available. They are used for VOC and background sampling. Badges are opened for sampling, worn on the person, sealed and sent off for analysis where the substances are desorbed and analysed. See more
