Collision cross section (CCS) measurements resulting from ion mobility–mass spectrometry (IM-MS) experiments provide a promising orthogonal dimension of structural information in MS-based analytical separations. As with any molecular identifier, interlaboratory standardization must precede broad range integration into workflows. In this study, we present reference drift tube mobility mass spectrometer (DTIM-MS) where improvements on the measurement accuracy experimental parameters...
Measuring the exposome remains a challenge due to range and number of anthropogenic molecules that are encountered in our daily lives, as well complex systemic responses these exposures. One option for improving coverage, dynamic throughput measurements is incorporate ion mobility spectrometry (IMS) into current MS-based analytical methods. The implementation IMS exposomics studies will lead more frequent observations previously undetected chemicals metabolites. LC-IMS-MS provide increased...
Cell line-specific, genome-scale metabolic models enable rigorous and systematic in silico investigation of cellular metabolism. Such have recently become available for Chinese hamster ovary (CHO) cells. However, a key ingredient, namely an experimentally validated biomass function that summarizes the composition, was so far missing. Here, we close this gap by providing extensive experimental data on composition 13 parental producer CHO cell lines under various conditions. We report total...
Within recent years there has been an increase in research focused on the design and application of organic polymer monoliths all areas separation science. This is largely driven by theoretical practical benefits that these materials should be able to provide, particularly terms improved biocompatibility high permeability. review summarises new developments this field with a focus approaches synthesis polymeric monolithic for analytical includes use alternative synthetic methodologies such...
The major benefits of integrating ion mobility (IM) into LC-MS methods for small molecules are the additional separation dimension and especially use IM-derived collision cross sections (CCS) as an ion-specific identification parameter. Several large CCS databases now available, but outliers in experimental interplatform IM-MS comparisons identified a critical issue routine identity confirmation. We postulate that different external calibration strategies applied traveling wave (TWIM-MS)...
Steroids play key roles in various biological processes and are characterized by many isomeric variants, which makes their unambiguous identification challenging. Ion mobility-mass spectrometry (IM-MS) has been proposed as a suitable platform for this application, particularly using collision cross section (CCS) databases obtained from different commercial IM-MS instruments. CCS is seen an ideal additional parameter steroids long-term repeatability interlaboratory reproducibility of...
3-Pyridylcarbinol ester derivatization introduces a universal probe for cryogenic gas-phase infrared spectroscopy of fatty acids that enables assignment the position and configuration carbon–carbon double bonds even in presence isomers.
A nutritious and healthy diet relies on consuming cereals with sufficient micronutrient content, making the production of nutrient-rich crops a crucial agricultural goal. Identifying key strategies for plant acquisition is essential, this especially critical regions where calcareous or nutrient-deficient soils limit bioavailability.Plants can enhance nutrient uptake by increasing exploration soil volume through root growth releasing exudates that facilitate mining. Barley, along other...
Micronutrient (MN) deficiencies, particularly of iron (Fe), zinc (Zn), and copper (Cu), are major constraints to crop productivity in arid semi-arid regions characterized by high-pH calcareous soils. Effective strategies for acquiring MN essential ensure high yields on nutrient-depleted soils produce MN-rich crops. In the case iron, grass species (Poaceae) increase Fe phytoavailability releasing root exudates called phytosiderophores (PS), which have capability chelate mobilize from soil,...
Concerning polymeric monolithic materials utilized in separation science, the structural and mechanical characteristics from nanoscopic to macroscopic scale remain of great interest. Suitable analytical tools are urgently required understand polymer monolith's constituent structure, particularly case nanoscale properties that tend develop gel porosity contact with a mobile phase ultimately affecting chromatographic performance. Herein described our first findings characterization...
