PhD in Quantitative Mass Spectrometry by LC-ESI-IT-MS, IGSM, Germany

Signal strength in mass spectrometry strongly depends on the chemistry and size of analytes and can therefore not simply be used for quantification. In the field of polysaccharide derivatives, e.g. cellulose ethers, the molar composition of complex oligomeric mixtures obtained by partial depolymerization of the polymer, need to be analyzed. Accuracy of quantitative data is of high importance for pattern evaluation of these chemically modified biopolymers.

In Electrospray Ionization (ESI), surface activity and electrophoretic mobility of analytes, solvent and solvation energy, play an important role for relative ion yields of the components of a mixture. In addition, instrumental parameters as skimmer voltages and target mass influence the ion current. Coupling of the MS to Liquid chromatrography (LC) can mitigate effects of competition of analytes, and allow to optimize individual measurement conditions. Aim of the project is to study and quantify the factors of influence. Therefore, defined oligosaccharide derivatives shall be synthesized as model compounds and their behavior be studied.

The Braunschweig IGSM aims at increasing the number of women in scientific positions. Female candidates are therefore particularly encouraged to apply.
You are required to hold an excellent university degree (master’s or equivalent degree) in physics, chemistry, electrical or mechanical engineering, mathematics, information technology or related fields. Please note that the entire program is run in English, so fluency in both written and spoken English is required. Skills in German are welcome.
You may be a member of the IGSM for up to 3 years. In your first semester, you will be accepted on a probationary basis.

Scholarship Application Deadline: 31 March 2011
