The GERSTEL MPS robotic pro offers the most advanced, easy to use and flexible means of automating SPME available. GERSTEL MAESTRO software allows features such as pre- and post-fiber derivatization, automated calibration curve preparation, sampling directly from vial and the choice of sample agitation or stirring by simple mouse click. With the automated tool exchange option, different fibers can be used in an analysis sequence and/or the SPME technique can be used in a multipart analytical method including headspace and liquid injection.
2:07“We couldn’t get more than three uses out of the SPME fiber, due to irreversible fouling. We can now do this in a completely automated fashion with the Twister and the GERSTEL system. We do the extractions simultaneously, do hundreds of measurements, and get great statistics on children with autism.”
“It’s still in an early stage of research; however we believe we will be able to predict the severity of autism [in individual children], and measure its progress before brain damage has occurred. We’ve created a reliable, rugged, accurate and sensitive test to give doctors accurate and precise measurements. This allows the physician to follow trends in patients that they never would have been able to observe before. We’ve brought this analysis to a new level of scientific readiness.”
Skip Kingston, PhD. Professor Bayer School of Natural and Environmental Sciences Chemistry & Biochemistry - Duquesne University“I’ve had a lot of requests for odor analysis from non-food places, like mattress makers, to find out what was causing odors in new mattresses. GERSTEL technology allows for unique applications. I would not be able to do what I’m doing without GERSTEL. Their instruments are able to provide more sensitivity than I’ve ever seen.”
“One class of potent odor chemicals that had been difficult to detect was carboxylic acids. With seq-SBSE, and multiSBSE, these chemicals can now be routinely monitored.”
“With Twister, I found chemicals in beer nobody had found. I didn’t know how good our data was. Then, a chemist from a beer company was really excited about our data.”
Ray Marsili Flavor Chemist / Consultant Marsili Consulting Group“We’re using GERSTEL technology, and the nice thing is that it’s geared toward flavor analysis, geared toward automation, and geared to be reproducible in ways that allow us look at this niche part of food chemistry.”
“For understanding the flavor changes in apple and orange juice, we’ve used Twister analyte extraction technology. We’ve used GERSTEL instrumentation on milk to determine how it can maintain its freshness for months. To see how we can preserve milk, and make it stable, we’ve used technology like the TDU and TDS units to understand vapor prints. That’s a great story for us, because we were trying to recreate off flavor compounds that come with milk storage.”
