Obviously, there are so many important people in Chemistry for me. These researchers have helped the advancement of chemistry. Right now, I´m going to write about an expert in Analytical Chemistry, Professor Janusz Pawliszyn, because his research is related to my doctoral thesis.
Janusz Pawliszyn's research focuses on the development and application of state of the art, integrated and automated analytical methods and instrumentation, for onsite analysis and monitoring. He works at University of Waterloo (Canada) doing research and teaching.
Recently, He won the EAS Award for Outstanding Achievements in Analytical Chemistry 2017 and he is part of the The Power List 2017 in Separation Sciences (Number 8 in the world).
In the 90´s, he invented solid-phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, which extracts different kinds of analytes from different kinds of samples. The importance is that the quantity of analyte extracted by the fibre is proportional to its concentration in the sample. The attraction of SPME is that the extraction is fast, simple, can be done usually without solvents, and detection limits are so low for certain compounds. There is a before and after of this great invention in analytical chemistry. This technology was patented to protect copyright.
SPME
This invention is important to me because I have used it in my thesis a microextraction technical based on the same principle, rotating-disk sorptive extraction (RDSE), which was created by my thesis director. With this new technique we are improving the disadvantages of the SPME technique. In the future, I would like to meet the teacher Pawliszyn and if it is possible, to do some internships with him.
I hope that you can meet him. Good look about that!
ResponderEliminarThe researh topic that you have is very interesting.
ResponderEliminarwow, now i know who invented that technique!
