Abstract

Mixing is an essential, yet challenging, process step for many Lab on a Chip (LOC) applications. This paper presents a method of mixing for microfluidic devices that relies upon electroosmotic flow. In physical tests and in computer simulations, we periodically vary the electric field with time to mix two aqueous solutions. Good mixing is shown to occur when the electroosmotic flow at the two inlets pulse out of phase, the Strouhal number is on the order of 1, and the pulse volumes are on the order of the intersection volume.

MALDI-TOF MS in lipidomics.

So far, matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) seemed to be nearly a synonym for protein analysis. However, there is growing evidence that this technique is also an useful tool in lipid analysis and lipidomics because of its fast, simple and convenient performance allowing to record mass spectra of cells, crude tissue or body fluid extracts or even intact tissue slices in a few minutes. On the negative side, however, the reproducibility of MALDI-TOF mass spectra depends significantly on the homogeneity of the co-crystals between matrix and analyte and different lipid classes are detected with different sensitivities. This is especially important because lipids with quaternary ammonia groups (e.g., GPCho) may prevent the detection of other lipid classes (e.g., GPEtn). This review starts with a short overview on traditional methods of lipid analysis with the focus on mass spectrometric methods and compares MALDI-TOF MS with other important ionization techniques. Afterwards, some landmarks in the development of MALDI-TOF MS will be introduced and some important examples in the field of tissue and body fluid lipid analysis will be discussed. This review ends with a short outlook and summary focusing on the advantages and drawbacks of MALDI-TOF MS in lipidomics.

Structural characterization of phosphatidyl-myo-inositol mannosides from Mycobacterium bovis Bacillus Calmette Guérin by multiple-stage quadrupole ion-trap mass spectrometry with electrospray ionization. I. PIMs and lyso-PIMs.

We described a multiple-stage ion-trap mass spectrometric approach to characterize the structures of phosphatidylinositol and phosphatidyl-myoinositol mannosides (PIMs) in a complex mixture isolated from Mycobacterium bovis Bacillus Calmette Guérin. The positions of the fatty acyl substituents of PIMs at the glycerol backbone can be easily assigned, based on the findings that the ions arising from losses of the fatty acid substituent at sn-2 as molecules of acid and of ketene, respectively (that is, the [M - H - R(2)CO(2)H](-) and [M - H - R(2)CHCO](-) ions), are respectively more abundant than the ions arising from the analogous losses at sn-1 (that is, the [M - H - R(1)CO(2)H](-) and [M - H - R(1)CHCO](-) ions) in the MS(2) product-ion spectra of the [M - H](-) ions desorbed by electrospray ionization (ESI). Further dissociation of the [M - H - R(2)CO(2)H](-) and [M - H - R(1)CO(2)H](-) ions gives rise to a pair of unique ions corresponding to losses of 74 and 56 Da (that is, [M - H - R(x)CO(2)H - 56](-) and [M - H - R(x)CO(2)H - 74](-) ions, x = 1, 2), respectively, probably arising from various losses of the glycerol. The profile of the ion-pair in the MS(3) spectrum of the [M - H - R(2)CO(2)H](-) ion is readily distinguishable from that in the MS(3) spectrum of the [M - H - R(1)CO(2)H](-) ion and thus the assignment of the fatty acid substituents at the glycerol backbone can be confirmed. The product-ion spectra of the [M - H](-) ions from 2-lyso-PIM and from 1-lyso-PIM are discernible and both spectra contain a unique ion that arises from primary loss of the fatty acid substituent at the glycerol backbone, followed by loss of a bicyclic glycerophosphate ester moiety of 136 Da. The combined structural information from the MS(2) and MS(3) product-ion spectra permit the complex structures of PIMs that consist of various isomers to be unveiled in detail.

Optimization of homonuclear 2D NMR for fast quantitative analysis: application to tropine-nortropine mixtures.

Quantitative analysis by (1)H NMR is often hampered by heavily overlapping signals that may occur for complex mixtures, especially those containing similar compounds. Bidimensional homonuclear NMR spectroscopy can overcome this difficulty. A thorough review of acquisition and post-processing parameters was carried out to obtain accurate and precise, quantitative 2D J-resolved and DQF-COSY spectra in a much reduced time, thus limiting the spectrometer instabilities in the course of time. The number of t(1) increments was reduced as much as possible, and standard deviation was improved by optimization of spectral width, number of transients, phase cycling and apodization function. Localized polynomial baseline corrections were applied to the relevant chemical shift areas. Our method was applied to tropine-nortropine mixtures. Quantitative J-resolved spectra were obtained in less than 3 min and quantitative DQF-COSY spectra in 12 min, with an accuracy of 3% for J-spectroscopy and 2% for DQF-COSY, and a standard deviation smaller than 1%.
