Our exposure facilities utilise, mainly, the ADG flow through nose-only exposure chambers and provide the following features:

• Multi-species exposure; rats, mice, rabbits and guinea pigs can be exposed using the same systems
• Exposure by other routes (dermal or by ingestion during grooming) is therefore minimised
• Exposure periods ranging from a few minutes to 6 hours per day can be accommodated
• Multiple tier chambers allow for a wide range of group sizes
• Substantially lower test material usage compared with whole-body systems
• Individual containment of exposure chambers prevents cross contamination and improves safety
• Whole body enclosure also available for acute toxicity studies

• Dust and liquid aerosols at low and high concentrations
• Gases including low concentration, toxic gases
• Vapours

Concentration

• Gravimetric
• Chemical analysis:
  • HPLC (Diode array, R.I. and fluorescence detection)
  • GC (with FID, NPD, ECD and FPD detectors)
  • Atomic absorption spectroscopy
  • Flame photometry
  • IR and UV/visiable spectrophotomtry
• Laser photometer aerosol monitoring

• Cascade impactor analysis
• Electronic distribution plotting

• Electronic, remote recording of temperature, humidity and oxygen concentration
• Continuous airflow monitoring

• Agrochemicals; EPA, EU and JMAFF requirements (including multiple active ingredient formulations)
• Notification of new chemicals; gases, volatile liquids and respirable particulates
• Emergency exposure studies; short exposure periods
• Extreme (high and low) concentration atmospheres
• Respiratory sensitisation
• Inhalation potential studies – allow assessment of a potential hazard
• Toxicity/Infecticvity studies – for microbial pest control agents
