Bioprocess Monitoring with Ultrasound-Enhanced ATR Mid-IR Spectroscopy



Bernhard Lendl and Cosima Koch of the Vienna University of Technology have developed a new method for on-line monitoring of fermentations using mid-infrared spectroscopy.

An interview with Cosima Koch and Bernhard Lendl, winners of a 2011 FACSS Innovation Award.Part of a new podcast series presented in collaboration with the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS), in connection with SciX 2012 — the Great Scientific Exchange, the North American conference (39th Annual) of FACSS.

Bernhard Lendl is the head of the working group on Process Analysis & Vibrational Spectroscopy at the Institute of Chemical Technologies and Analytics Division of Analytical Chemistry at the Vienna University of Technology (Vienna, Austria). In 2002 Lendl received the Fritz Pregl award of the Austrian Academy of Sciences. In 2003 he was awarded the Fritz Feigl award of the Austrian Society of Analytical Chemistry.

Cosima Koch studied technical physics at Vienna University of Technology, focusing on ultrasonics, medical physics and biophysics. She joined the workgroup in May 2010 as a fellow of the "Applied Bioscience Technology" (AB-Tec) grad school to do her PhD. Her research interest lies in on-line detection and quantification of stress in yeast cells using an ultrasonic enhanced fibre optic mid-IR sensor.

Lendl, Koch, and colleagues won a FACSS Innovation Award at the 2011 SciX conference for their presentation:

C. Koch, M. Brandstetter, S. Radel, and B.Lendl, “Ultrasound Enhanced ATR mid-IR Fibre Optic Probe for Spectroscopy of Particles in Suspensions,“ paper presented at SciX 2011, Reno, Nevada, 2011.

The FACSS Innovation Awards were launched at the 2011 SciX conference to showcase the newest and most creative science debuted orally at the conference.

More about the SciX conference:

The traditional North American meeting of FACSS is now SciX - The Great Scientific Exchange. SciX covers the whole of analytical chemistry with an emphasis on emerging technologies. SciX carries the FACSS tradition of a strong technical program (over 100 symposia), many prestigious awards, exhibits, a variety of workshops, an employment bureau and multiple social networking opportunities.

SciX is the National Meeting of the Society for Applied Spectroscopy (SAS).
