AccuSizer ® A2000 USP Liquid Particle Counter The most advanced instrument available for USP <788> Particulate Matter Injections Testing The new AccuSizer ® A2000 USP system is the most advanced instrument available for USP <788> testing. It meets or exceeds all requirements in USP <788> by providing size and count data at the required 10 and 25 µm and easily passes all system standardization tests described in USP <1788>. The unique technology designed into the A2000 USP counter provides capabilities not available in any other liquid particle counter due to each component being the highest specification/ performance on the market. The A2000 USP is not just a liquid particle counter; it is a sophisticated particle size analyzer as well.
• Measure size and concentration from 0.5 –400 µm
• Sample conservation after measurement
• 64 size channels defining the complete distribution
• 21 CFR 11 features with security management
• Up to 32 user defined channels
Classical light obscuration sensors familiar to pharmaceutical scientists performing USP <788> testing typically have a lower particle size limit near 2 µm. The LE400 sensor uses two detectors (extinction + scattering) to extend the range to 0.5 – 400 µm.
A 64 channel pulse height analyzer provides high resolution results so this is not just a counter – use it as a particle size analyzer on any of your other samples. The AccuSizer software allows conversion from number to volume distribution so results can be compared to other techniques like laser diffraction.
The AccuSizer software is a sophisticated package that automates USP <788> testing including pass/fail criteria and acceptance approval.
