One of the most important poisons for humans are dioxins. Dioxins
and PCB’s are found ubiquitously in the environment and
migrate into food. Do you see the possibility of applying GC-TOFMS
and GCxGC-TOF-MS technology in this area?
The scope of application of the analysis of dioxins in foods is strictly regulated.
This actual analysis is challenging and also very costly. Currently,
GC-TOF-MS or GCxGC-TOF-MS is not considered a routine method in
this field. However, in collaboration with the working group led by Prof.
Jef Focant at the University of Liège, we have analysed reference samples
using our LECO Pegasus BT4D system. We are able to demonstrate the
required detection limits/ sensitivity.
In addition, other interesting compounds were identified, indicating
that the extension of the existing target compound analysis with
“Non-Target-Screening,” promises new findings (The results were presented
during the „Dioxin 2018“ in Krakow, PL, the editor). We will continue
to work on that.
What is the future of the GC-TOF-MS and GCxGC-TOF-MS technology
in the food sector?
The technology has existed for more than 20 years. However, specific interesting
and appropriate analytical issues such as MOSH/MOAH or in regard
to the general question of “Non-Target-Compound-Analysis” has occurred
only recently. This sophisticated technology is robust i.e. applicable to routine
analysis. I understand the shyness to break away from Single-Quadrupole and
Triple-Quadrupole-Systems for routine purposes and to test how much more
can be derived from a Time-of-Flight Mass spectrometer, however LECO has
been active in this field of application for more than two decades. We support
our users with bespoke training and application support concepts. Together
with our cooperating partners we are working on the validation of methods
in the areas we’ve discussed. I am convinced that we will see more TOF-MS in
Food labs for routine-analysis in the future.
It is many years since Carl. E. Schultz developed the world's first carbon
analyzer for the steel industry, in St. Joseph / Michigan in 1936 . By doing
so, he laid the foundations for one of the most innovative companies in
the analytical industry.
Every day, LECO instruments are used to find solutions to the most
complex and challenging analysis applications around the world.
LECO offers a wide range of advanced analytical equipment, including
elemental determination by combustion / fusing of organic and
inorganic materials, thermogravimetry, calorimeters, GDS spectrometers,
