The Helmut Hund GmbH presents the first fully automated pollen monitoring system worldwide.
High-precision pollen monitoring online with the Pollen Monitor BAA500
Widespread disease pollen allergy
Pollen allergies have become a widespread disease. Every year, during the bloom of many plants, about 30% of the citizens of the Federal Republic of Germany suffer from acute symptoms that reach from allergic rhinitis to life-threatening anaphylactic shocks. Not least because of new or extremely aggressive pollen like Ambrosia, the life quality of allergy sufferers is heavily distressed (Ragweed or Ambrosia artemisiifolia).
Needs of allergic persons
For their daily routine, allergic persons strongly depend on up-to-date information about pollen counts in their area (pollen monitoring), e. g. to adjust their daily medications or to plan their open-air activities.
The method used today for the collection and analysis of pollen is manual and causes delays and inaccuracies in the results. The pollen traps are not emptied on a daily base and the analysis under a microscope depends on the experience of the pollen counter.
In cooperation with the Fraunhofer Institute for Applied Information Technology (FIT), Sankt Augustin and the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM), Hannover, Helmut Hund GmbH has developed the BAA500 (Bio Aerosol Analyzer) and reached series production readiness.
The BAA500 offers the following features and benefits:
- High-precision results in real-time
- Independent of temperatures and seasons
- Fully automated process
- Data transfer via internet and app
- Subsequent result verification and identification of new pollen species possible
Further information on its operating principle
- Up to date pollen information based online data
Transmission of pollen concentration in a cycle of 1 – 3 hours
- High precision and accuracy
- Currently the BAA500 recognizes 38 different kind of pollen. By training the system it can be extended to other pollen species
An outstanding tool for clinical tests
Within the framework of clinical studies or for the investigating of patients’ reactions on allergic reactions on pollen including the effectiveness of medicaments and the correlation of discomfort and pollen concentration is of high importance. By means of the BAA 500 both, the speed and accuracy of investigations are significantly enhanced
With the help of our Pollen Monitor BAA500, it is possible to implement automatic pollen monitoring. An electronical pollen information system can determine the pollen count on various locations and can be used for a pollen forecast by the data collected on site.
For the evaluation, the fully automatic light microscope built into the BAA500 takes image stacks of a number of positions on the sample. These stacks are stitched to a coherent high-resolution picture with great depth of sharpness.
Subsequently, the classification starts using different descriptors for the characteristics of the objects, with which the pollen can be identified with high accuracy and precision. As a result of the evaluation, the BAA500 continuously creates tables which are accessible via internet at any time.
