The latest results of the automatic assesment of hop quality are available under: http://www.lemnatec.de/hop.pdf. The hop quality of the German Hallertau hop which according to the Barth Report 2001/2002 is more than one quarter of the world hop production has been automatically assessed with the LemnaTec Scanalyzer system this year. To double check the reproducibility of the automatic hop quality assessment another LemnaTec Scanalyzer system has been set up in the German hop region Tettnang. Both Scanalyzer units assess the hop quality automatically according to colour classifications and quality rules, which have been developed last year during the hop harvest 2002 at NATECO2 Ltd. (Wolnzach) a subsidiary company of Joh. Barth & Son (Nurnberg) and Hopfenverwertungsgenossenschaft HVG (Wolnzach). For this purpose about 400 different hop samples with 10 replicates per hop sample have been scanned and the results of the automatic quality assessment were compared with those of the conventional manual/visual quality assessment. The promising results of this investigation can be found in article from Roland Schmidt, Angelika Köberlein and Adrian Forster which has been publicated in the Hopfenrundschau. The article can be downloaded at
http://www.lemnatec.de/hop.pdf (by kind permission of NATECO2) After the successful second test in Hallertau and Tettnang a global standard hop quality assessment network with direct database connection for hop logistics and accountancy could be developed and established.
LemnaTec has developed a new generation of Daphnia magna and Ceriodaphnia dubia Detection System for both acute and chronic toxicity testing. LemnaTec's SAW Daphnia automatically measures mobility and counts all juvenilesWith the LemnaTec Scanalyzer the evaluation of the Daphnia Magna and Ceriodaphnia dubia test is fast and reproducible and corresponds to the current standards (e. g. ASTM E1295-01, EPS 1/RM/21, EPA/600/4-1002.0, ISO 6341, ISO 10706, OECD 202), . The software is designed for a simple and efficient use in the laboratory practise. Special computer know-how or knowledge of image processing is not necessary. Using the LemnaTec Scanalyzer guarantees constant recording conditions and high quality of the images. Therefore a high-resolution camera with a 1280 * 960 pixel resolution is used. With the high resolution, Daphnia magna and also Ceriodaphnia dubia can be automatically counted in liquid medium and standard volumes.
Based on these parameters the Software is able to distinguish between juvenile and adult generation and to eliminate particles visible in the test solution. The test setup gives the opportunity to measure samples at different times and concentration steps.Interested?

A big step forward to international bio-testing with higher plants
At the ISO meeting in Florida May, 2002 a broad international consensus
accepted the duckweed growth inhibition test as the first growth
inhibition test only based on calculation of growth rate. A similar
consensus was achieved for algae.
The duckweed test will now be prepared for an ISO DIS version taking
into
account the high priority of higher plant testing.For further information please contact:
