The measurements were accomplished with a flow diffusion analysis (FDA) unit from the TRACE Analytics GmbH, Braunschweig, Germany. The diffusion analysis is based on the UV-absorbance of acetic acid at 205 nm. The measurement was achieved by the separation of an acceptor and a carrier stream (acidified fermentation broth) using a gas permeable polytetrafluoroethylene (PTFE) membrane, whereby broth constituents that would otherwise disturb the UV-measurement of acetic acid, are held back efficiently. Merely, the fermentation by-products, e.g. formic acid, is capable of diffusing through the membrane. While formic acid can disturb the measurement, carbon dioxide does not absorb at 205 nm. The method operates with time-dependent sample enrichment. During the analysis, a small volume of the acceptor stream is stopped for a defined time interval in the acceptor chamber. During this period, the gaseous acetic acid diffuses through the membrane and is enriched in the acceptor chamber. Subsequently after the enrichment, the acceptor stream flows through a UV-detector. The intensity of the signal is proportional to the acetic acid concentration. Online measurements in bioreactors via a sterile filtration probe have been accomplished. A linear calibration in the range of 0.5-5.0 g/L acetic acid with a relative standard deviation of <5 \% was obtained. A sampling rate of 8 samples per hour was possible. The system was applied for the determination of acetic acid in E. coli fermentation broth. The instrument is easy to clean, very user-friendly and does not require any toxic or expensive reagents.}, language = {en} } @article{TimmeHuelk2008, author = {Timme, Michael and H{\"u}lk, Fabian}, title = {Mieterh{\"o}hungsverlangen bei unwirksamer Sch{\"o}nheitsreparaturklausel}, series = {Monatsschrift f{\"u}r deutsches Recht : MdR ; Zeitschrift f{\"u}r die Zivilrechtspraxis. 28 (2008), H. 22}, journal = {Monatsschrift f{\"u}r deutsches Recht : MdR ; Zeitschrift f{\"u}r die Zivilrechtspraxis. 28 (2008), H. 22}, isbn = {0340-1812}, pages = {1249 -- 1251}, year = {2008}, language = {de} } @article{Timme2008, author = {Timme, Michael}, title = {Vollstreckung in Steuererstattungsanspruch - Verfahrensrechte im Festsetzungsverfahren}, series = {Neue juristische Wochenschrift : NJW. 61 (2008), H. 23}, journal = {Neue juristische Wochenschrift : NJW. 61 (2008), H. 23}, isbn = {0341-1915}, pages = {1675 -- 1677}, year = {2008}, language = {de} } @article{Timme2008, author = {Timme, Michael}, title = {Mietkaution in der Insolvenz des Vermieters}, series = {Neue Zeitschrift f{\"u}r Miet- und Wohnungsrecht : NZM. 11 (2008), H. 12}, journal = {Neue Zeitschrift f{\"u}r Miet- und Wohnungsrecht : NZM. 11 (2008), H. 12}, isbn = {1434-677X}, pages = {429 -- 431}, year = {2008}, language = {de} }
