High Resolution ELPI®+

18.12.2018

The Dekati® High Resolution ELPI®+ (Electrical Low Pressure Impactor, HR-ELPI®+) is an improved version of the widely used ELPI®+ instrument. Since 2024, the HR-ELPI®+ is offered as the standard ELPI®+ version.

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®+.
