What is the typical accuracy of a particle counter like the APA2000?

The accuracy for this class of equipment is generally high, with typical sizing accuracies of ±2% and count accuracies often better than ±1% when properly calibrated and operated.

Can this unit handle both aqueous and non-aqueous samples?

Many particle counters of this type are designed to handle both aqueous and certain non-aqueous samples, provided compatible electrolytes and dispersants are used. Buyers should confirm specific solvent compatibility with the seller.

What kind of calibration is required for a particle counter?

Calibration typically involves using certified reference materials (e.g., polystyrene latex spheres) of known sizes to ensure accurate sizing and counting. Regular calibration checks are recommended.

Is specialist training required to operate this equipment?

While user-friendly, some basic training is generally recommended for optimal operation, sample preparation, and data interpretation to ensure reliable results.

What consumables are typically needed for ongoing operation?

Common consumables include electrolytes, dispersants, and potentially aperture tubes which may need replacement over time due to wear or blockage.

Typical Specifications

Typical particle size range: For this class of equipment, a typical particle size range might span from sub-micron to several hundred microns.
Measurement principle: Units of this type commonly employ the electrical sensing zone (Coulter principle) for particle counting and sizing.
Sample volume: Typically, sample volumes for analysis can range from microlitres to several millilitres, depending on the application.
Throughput: Commonly, these systems offer analysis times from seconds to a few minutes per sample, impacting overall throughput.
Power supply: Units of this type commonly require a standard single-phase electrical supply, typically 230V, 50Hz for the UK market.
Data output: Most units provide digital data output via USB or Ethernet for integration with laboratory information management systems (LIMS).
Maintenance requirements: Routine maintenance typically involves cleaning the aperture tube and replacing electrolytes or sheath fluids.
