APSS 200 Parenteral Particle Counter

Question
What are the environmental conditions and calibration parameters for particle counter APSS 200 liquid sampler?

Answer

The environmental conditions must meet temperatures between 4-40° C and humidity between 0-95% (non-condensing). Other parameters/specifications include:

• The instrument size range is 2-125 um
• The instrument samples 100% of the fluid (and particles) passing through the instrument
• The instrument is calibrated every year
• The maximum particle concentration is 10,000 (cumulative) particles per mL
• The instrument should only sample particles in deionized water
• Calibrations are performed to standards from NIST, ISO 4402 and ASTM-F658
