Pharmaceutical Aerosol Measurement
The ELPI®+(Electrical Low Pressure Impactor) is an improved version of the widely used ELPI® system. This instrument enables the measurement of real-time particle size distribution and concentration in the size range of 6 nm – 10 μm, with up to a 10 Hz sampling rate. The ELPI®+ can also be used for real-time particle charge distribution and for gravimetric impactor measurements. Chemical analysis of the size-classified particles may also be conducted post-measurement.
Benefits of the ELPI®+ system include:
- Real-time stand-alone operation
- Wide sample concentration range
- Wide particle size range
- The ability for post-measurement chemical analysis of size classified particles
- Real-time particle charge distribution and gravimetric measurements
High Resolution ELPI®+
The High Resolution ELPI®+ operates in the same manner as the ELPI®+ but features a data inversion algorithm that provides the user with real-time particle size distribution in up to 500 size classes in the size range of 6 nm - 10 µm. The data inversion software may be purchased separately and used with the traditional ELPI®+.
