[vc_row][vc_column][vc_column_text]Promo\u00ae<\/sup>\u00a01000 is a light-scattering aerosol spectrometer system for particle size analysis and concentration determination that can be equipped with all welas\u00ae<\/sup>\u00a01100 and 1200 sensors. These sensors allow reliable measurement in the concentration range from < 1 particle\/cm3<\/sup>\u00a0up to 5 \u2022 105<\/sup>\u00a0particles\/cm3<\/sup>.<\/p>\n

With Promo\u00ae<\/sup>\u00a01000 particles sizes above 120 nm can be reliably measured, as the special high power xenon high pressure lamp with very high light intensity and the photomultiplier are directly integrated in the aerosol sensor.<\/p>\n

Unique are up to four measuring ranges in only one device:
\n\u2022<\/span>\u00a0\u00a0\u00a0\u00a00.12 \u00b5m \u2013 3.5 \u00b5m (additionally in welas\u00ae<\/sup>\u00a01000 and Promo\u00ae<\/sup>\u00a01000)
\n\u2022<\/span>\u00a0\u00a0\u00a0\u00a00.2 \u00b5m \u2013 10 \u00b5m
\n\u2022<\/span>\u00a0\u00a0\u00a0\u00a00.3 \u00b5m \u2013 17 \u00b5m
\n\u2022<\/span>\u00a0\u00a0\u00a0\u00a00.6 \u00b5m \u2013 40 \u00b5m.<\/p>\n

Promo\u00ae<\/sup>\u00a01000 is famous for up to 128 size channels per measuring range and a concentration range from < 1 particle\/cm3<\/sup>\u00a0to 5 \u2022 105<\/sup>\u00a0particles\/cm3<\/sup>.<\/p>\n

The best size classification accuracy and the best size resolution are guaranteed by the following special features (see Graph 1):
\n<\/b>\u2022<\/span>\u00a0\u00a0\u00a0\u00a0White light and 90\u00b0 light-scattering detection
\n\u21d2\u00a0Unambiguous calibration curve
\n<\/b>\u2022<\/span>\u00a0\u00a0\u00a0\u00a0Patented T-aperture
\n\u21d2\u00a0No border zone error
\n<\/b>\u2022<\/span>\u00a0\u00a0\u00a0\u00a0New digital individual signal processing
\n\u21d2\u00a0Coincidence detection and correction of the individual signal making it possible to measure higher concentrations<\/b><\/p>\n

A touch display ensures user-friendly operation. Measurements can be started easily, and all data, such as the current number distribution and the number concentration, as well as 24 further statistical values, can be evaluated and displayed in real time. All incoming data can be stored with a max. temporal resolution of 1 s. For data transfer, Promo\u00ae<\/sup>\u00a0can also be integrated into a company network.<\/p>\n

Promo\u00ae<\/sup>has a standard interface and can be controlled by a process control system or by a simple Labview program.\u00a0The Promo\u00ae<\/sup>\u00a0measurement technology:<\/b><\/p>\n

Promo\u00ae<\/sup>\u00a0has a new, fast 20 MHz signal processing processor, which analyses the progression of each particle signal.<\/p>\n

This makes it possible to recognise coincidental events in light scattering measurement technology at the individual signal and correct them (according to Dr. Umhauer \/ Prof. Dr. Sachweh). This way it is possible to increase the maximum concentration limit up to 5 \u2022 105<\/sup>\u00a0particles\/cm3<\/sup>.<\/p>\n

Furthermore, the new signal detection electronics, which include a new, powerful logarithmic A\/D converter, allow particles of 120 nm to be measured with a 50 % counting efficiency.<\/p>\n

High classification accuracy, high resolution capability and a high counting efficiency are the prerequisite for unambiguous particle measurement.<\/b><\/p>\n

The Promo\u00ae<\/sup>\u00a0is characterized by its very high counting efficiency starting from 0.12 \u00b5m!<\/p>\n

The Promo\u00ae<\/sup>\u00a01000 sensors:<\/b><\/p>\n

The welas\u00ae<\/sup>1100 and 1200 aerosol sensors are characterized by the fact that a powerful light source and the photomultiplier are directly integrated in the sensor. This technology offers the best size resolution, the best classification accuracy and a low detection limit.<\/p>\n

The size of measurement volume is crucial for coincidence-free particle size and particle number measurement.<\/p>\n

With measurements in coincidence, the diameter is measured too large and the number too small. Theoretically, for a coincidence\u2010free measurement, i.e. maximum one particle in the measuring volume, at a number concentration of 103<\/sup>particles\/cm3<\/sup>the measurement volume extension must not be higher than 1 mm3<\/sup>.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
