BIOTRAK® Real-Time

Viable Particle Counter

Application Notes

 
 
TSI has a variety of Application Notes available to help you learn more about the BIOTRAK® Real-Time Viable Particle Counter and its applications. Topics include:  
BioTrak 
 
  • Principle of Operation
    The BioTrak Real-Time Viable Particle Counter is a full featured instrument that detects the total number of particles in the air as well as determining which of those particles are viable in nature. Additionally, the BioTrak product incorporates a particle collection filter so the optically analyzed particles are available for subsequent speciation analysis. The BioTrak Particle Counter incorporates proven technologies leveraging TSI’s experience in particle measurement theory, instrument development, and calibration.
     

 

  • Importance of a Good Non-Viable Measurement
    A non-viable airborne particle counter is a misnomer. Current airborne particle counting technology such as found in the TSI AEROTRAK® particle counters, size and count all particles that pass through its viewing volume, it does not matter whether the particle is viable or non-viable. When an airborne particle counter displays 1 particle count at 5 µm it may or may not be viable, the instrument is unable to tell the difference. The great news now is that the BioTrak Real-Time Viable Particle Counter will be able to tell the difference.
     
 
  • Discrimination Capability
    The BioTrak Particle Counter is a full-featured instrument that detects the total number of particles in the air as well as determines which of those particles are viable in nature. Additionally, the BioTrak Particle Counter incorporates a particle collection filter so the optically analyzed particles are collected and available for subsequent speciation analysis. The BioTrak Particle Counter incorporates proven technologies leveraging TSI’s experience in particle measurement theory, instrument development, and calibration.
     
 
  • Sample and Collection Efficiency
    This Application Note presents issues related to aerosol sample and collection efficiency during various stages of the aerosol path in the BioTrak Particle Counter, and relates those efficiencies to other methods, like Active Air Samplers. When applying a viable particle counter, or any particle device in a cleanroom, proper characterization of the product is important so results can be understood, leading to root cause identification, and ultimately to continual improvement.
     
 
  • Facility Monitoring Systems
    This application note will demonstrate how real-time viable particle count data will lead to improved root cause investigations when a BioTrak Particle Counter is integrated into an FMS system. Improved root cause investigations and the resulting increased process knowledge is in line with current regulatory initiatives and expectations.
