My Ph.D. thesis "Development of packed capillary high temperature
liquid chromatography utilizing light scattering and inductive coupled plasma
mass spectrometry detection" was based on the development of high
temperature liquid chromatography on packed capillary columns with nonaqueous
mobile phases. This is a technique ment for the separation of heavy compounds
with low water solubility. The choise of detection was laser light-scattering,
and inductive coupled plasma mass spectrometry. To deal with volumetric
flowrates less than 10 microliter/min, it was necessary to develop a interface
for the coupling of the separation technique to the two detectors. The same
interface principle with small modifications was used.
I defended my thesis 10.desember 1999, and is currently working as the c.e.o. of G&T Septech
