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
The Dekati® Bipolar Charge Analyzer (Dekati® BOLAR™) is the first, commercially available instrument capable of measuring bipolar electrical charge size distribution of inhalation aerosols. The BOLAR™ can separately detect positively and negatively charged particles in five different particle size fractions. After the charge measurement, negatively and positively charged particles can also be analyzed enabling the determination of charge to mass ratio in different particle size fractions. In addition to these significant capabilities, the BOLAR™ also features:
- Real-time measurement
- Chemical analysis of collected particles
- Sample flow rate 30 – 90 lpm
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®+.
