PQ Check Standard, Tri-Mix for PSS Accusizer™ Syringe Sampler (SIS) Configuration

PQ Check Standard, Tri-Mix for PSS Accusizer™ Syringe Sampler (SIS) Configuration

• Tri-modal PQ check standard designed to verify size and count accuracy of the Particle Sizing Systems (PSS) Accusizer model 780 SPOS instrument in the Syringe Injection Sampler (SIS) configuration
• Volume: 500 mL
• Standard material: NIST traceable size Polystyrene latex (PSL) spheres
• Nominal sizes and concentrations of standard particles:
  • 0.8 µm PSL – 3,500 particles/mL
  • 2 µm PSL – 800 particles/mL
  • 5 µm PSL – 200 particles/mL
  • Product batch will be ± 10% of the nominal concentration; individual standard bottles will be certified ± 15% of the mean concentration and particle sizes are certified ± 5% of the standard size (± uncertainty)

The Certificate of Conformance includes actual concentration testing data and mean size
