PQ Check Standard, 25μm for PSS SIS Config
600-PA
PQ Check Standard, 25μm for PSS SIS Config., 250 mL Bottle
- Designed specifically as a single-mode peak PQ check standard to verify proper operation of the Particle Sizing Systems (PSS) Model 780 Accusizer SPOS instrument used in the Syringe Injection Sampler (SIS) configuration.
- Volume: 250 mL
- Standard material: NIST traceable size Polystyrene latex (PSL) spheres
- Nominal sizes and concentrations of standard particles:
- 25μm PSL – 150 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 Analysis includes actual concentration testing data and mean size.
