A rapid procedure for obtaining information on changes in particular characteristics of urine as the most frequently taken biosample is presented. The relationship between the output data of an array of piezoelectric sensors based on different micro- and nanostructured phases and the standard characteristics of clinical urine analysis is discussed....

AbstractThe control of the degradation of monoclonal antibodies is one of primary steps of the biologics development process. Traditionally a range of chromatographic and electrophoretic procedures is used for this purpose. However, the most comprehensive information about the degradation process can be obtained using a multiple attribute method (M...

AbstractThe results of a study of the pathways of ion formation from organic compounds in Atmospheric Pressure Laser Plasma Ionization (APLPI) are presented. The instrumental implementation of the method is based on its combination with a high-resolution mass analyzer. Solid dosage forms and also physiologically active compounds were studied. It wa...

AbstractSupercritical fluid chromatography (SFC) in combination with mass spectrometry is a promising alternative to traditional chromatographic methods for the separation of polar nitrogen-containing compounds. The specificity of carbon dioxide-based mobile phases, used in this method, can affect the processes of the mass-spectrometric ionization ...

AbstractWe developed a method for quantitatively analyzing some components of the unsaponifiable fraction of edible oils and validated its characteristics. The component composition of the unsaponifiable fraction of 26 edible oil species was studied by gas chromatography/mass spectrometry. Squalene, sterols, and triterpene alcohols were quantified ...

AbstractAtmospheric pressure photoionization Orbitrap mass spectrometry is a promising tool for studying lignin. It ensures the detection of thousands of lignin oligomers with molecular weights of up to 1.5–2 kDa and the reliable determination of their elemental compositions. In the present work, the effects of the resolving power of the mass analy...

AbstractThis review is devoted to the consideration of mass spectrometric platforms as applied to omics sciences. The most significant attention is paid to omics related to life sciences (genomics, proteomics, meta-bolomics, lipidomics, glycomics, plantomics, etc.). Mass spectrometric approaches to solving the problems of petroleomics, polymeromics...

AbstractWe studied the interaction of acyl derivatives of carbocyclic alcohols of steroid structure with nitrogenous bases in the ion source of a “direct analysis in real time” (DART) mass spectrometer. The protonation of esters in the DART plasma is accompanied by the elimination of a corresponding acid (acyl derivatives of cholesterol, β-sitoster...
