Gas Mixtures

Anaesthetic Mixtures: Gas Chromatography

acids and peptides due to the manifold separation modes that can be applied. Short analysis times, easy manipulation of separation conditions and small injection volumes (nanolitres) are further advantages. The Reld of biomedical and clinical amino acid and peptide analysis is still under investigation, especially as the transfer and adaptation of the separation modes to a broader range of real...

Heteronuclear quantum gas mixtures

In this PhD tutorial article, we present experiments with quantum degenerate mixtures of fermionic and bosonic atoms in 3-dimensional optical lattices. This heteronuclear quantum gas mixture offers a wide range of possibilities for quantum simulation, implementation of condensed matter Hamiltonians, quantum chemistry and ultimately dense and quantum degenerate dipolar molecular samples. We show...

PDAE Formulations of Gas Pipes with Gas Mixtures

A PDAE model of a multicomponent gas pipeline has been formulated and solved using the ode15s solver of Matlab. The model with boundary conditions allows for reactions and di usion. Also, general cubic equations of state for pressure and enthalpy are described. To simplify the implementation at this stage, a non-reactive, non-di usional model with fixed feed composition is considered, and multi...

Analysis and Approximation of Multicomponent Gas Mixtures

We consider a generalized system of Euler equations that describes the inviscid ow of a mixture of diierent gases. Systems of conservation laws of this type occur typically in the context of the numerical simulation of reacting gas ows. Results concerning the mathematical properties of the above model are presented. It turns out that a simple property of the thermodynamical equation of state en...
