Dekati - Model High Resolution - ELPI+
From Fine Particle Measurement - Real-Time Aerosol Measurement
The Dekati High Resolution ELPI+ (Electrical Low Pressure Impactor, HR-ELPI+) is an improved version of the widely used ELPI+ instrument. The High Resolution ELPI+ utilizes a data inversion algorithm that gives real-time particle size distribution in up to 500 size classes 6 nm – 10 μm. Other High Resolution ELPI+ features include wide particle sample concentration range, robust structure and possibility to characterize chemical composition of size classified particles after the real-time measurement. The latest addition to the HR-ELPI+ features is a new Data Analysis Tool software that makes data analysis and visualization fast and easy for the instrument operator. This new tool comes with particle number, LDSA and mass concentration (6nm-2.5 μm) calculations for the HR-ELPI+.
