The model indicates that in most cases more than 80% of the doubly charged ions are produced from singly charged ions.
Also, we have shown that the coincidence data contains information about the structure of the samples and that with coincidence counting, an estimate of the yield of secondary ions can be obtained without knowledge of how many primary ions strike the surface.

What are the major cations?5 answersThe major cations are sodium, potassium, calcium, magnesium, copper, iron, and mercury. Sodium, potassium, calcium, and magnesium are of greatest importance in anaesthesia and intensive care. In the context of water quality and ecological integrity, the major cations are calcium, magnesium, sodium, potassium, and aluminum. These major cations have important biological functions, biogeochemical relationships, and ecological roles that influence the ability of an aquatic ecosystem to sustain life forms and active food webs. They are present in different concentrations in surface waters and are influenced by various hydrologic factors and processes such as atmospheric deposition, mineral weathering, ion exchange, microbial mineralization, biological assimilation, sedimentation, and geochemical precipitation reactions. The concentrations of major cations in surface waters can vary, but most surface waters contain mixtures of major cations ranked in the following order of abundance: calcium, magnesium, sodium, and potassium.

What are the most used sampling system to sample VOCs ?
5 answers
The most commonly used sampling systems for volatile organic compounds (VOCs) include sorbent tubes or cartridges, air sample bags (such as Tedlar bags), glass air sampling units, canisters, and solid-phase microextraction (SPME). In India, around 65% of researchers utilize gas chromatography-based Flame Ionization Detection (GC-FID) for VOC characterization, with passive sampling using sorbent tubes with activated carbon being a prevalent method. Additionally, new portable and programmable VOC samplers have been developed to enable spatially and temporally resolved measurements, offering a simple and low-cost solution for sampling VOCs. Different methods like direct-breath SPME, Tedlar bag sampling, and cryotransfer have been compared for breath VOC sampling, each with its own advantages in terms of sensitivity, speed, and efficiency. Overall, a variety of sampling methods are employed to detect VOCs in different environments, each catering to specific needs and preferences.
What are the topics where VOCs can be studied?
10 answers
Volatile Organic Compounds (VOCs) are studied across a wide array of topics, reflecting their significant impact on various aspects of human health, environment, and industry. The research on VOCs spans from their role in medical diagnostics and disease prediction to their influence on indoor and outdoor air quality, as well as their implications in atmospheric chemistry and climate change. In the medical field, VOCs are investigated for their potential as noninvasive biomarkers for detecting and discriminating between healthy and diseased states, including cancer and neurodegenerative diseases. This involves analyzing VOC profiles in biological fluids such as breath, urine, and feces to understand the molecular mechanisms behind diseases and develop personalized screening and diagnostic tools. Specifically, VOC analysis of vaginal swabs has shown promise in predicting preterm birth, demonstrating the diagnostic potential of VOCs in obstetrics. VOCs are also a major concern in terms of indoor air quality, with research focusing on their emissions from building materials, furniture, and other sources. This area of study aims to understand the health effects of VOC exposure in indoor environments where people spend a significant portion of their time. Furthermore, VOCs play a critical role in atmospheric chemistry, acting as precursors to secondary pollutants like ozone (O3) and secondary organic aerosols (SOA), which affect air quality and climate. Studies in this field include long-term in-situ atmospheric measurements to characterize VOC variability, sources, and trends, as well as the impact of human activities and meteorological conditions on VOC levels. Additionally, the transformation of VOCs in cloud environments and their contribution to aerosol formation is another area of active research, highlighting the complex interactions between VOCs, atmospheric chemistry, and climate dynamics. In the context of environmental monitoring and regulation, understanding VOC emissions is crucial for devising strategies to improve air quality. Research in this area includes reviewing observation-based estimations of VOC emissions and source structures, particularly in regions with severe pollution issues like China. Lastly, advancements in analytical techniques and technologies for VOC analysis, such as gas chromatography, mass spectrometry, and sensor-based approaches, are continuously explored to enhance the speed, accuracy, and cost-effectiveness of VOC detection in various applications. In summary, VOCs are studied in diverse topics ranging from medical diagnostics, indoor air quality, atmospheric chemistry, environmental monitoring, to analytical method development, reflecting their widespread relevance and impact.
Can deriviation with qBBr be used for quantification of thiols in natural samples??
5 answers
Derivatization with qBBr can indeed be utilized for the quantification of thiols in natural samples. This method allows for the estimation of thiol concentrations in biomacromolecules and cell membranes, including small thiols like cysteine and glutathione, down to approximately 50 nM without the need for separation and prior concentration. Additionally, the development of a stable isotope-dilution high-performance liquid chromatography tandem-mass spectrometry (LC-MS/MS) method enables the simultaneous quantification of total H2S and other abundant thiols in biological matrices, providing a robust approach for accurate quantitation of thiols, including H2S, in complex biological samples. These methodologies offer selective and reliable means to quantify thiols in various sample types, facilitating comprehensive studies of thiol concentrations in natural environments and biological systems.
