Generally, the following analytical techniques are used to determine the different classes of unknowns: Organic Unknowns Volatile Gas Chromatography Mass Spectroscopy (GCMS), Dynamic Headspace GCMS (D-HMS), Headspace GCMS (HGCMS), Desorption Mass Spectroscopy (DMS) Non-Volatile Nuclear Magnetic ...
Mass spectrometry & spectroscopyHow Is NMR Spectroscopy Used?Request information The first Nuclear Magnetic Resonance (NMR) beams were detected in the 1930s by a team of researchers from Columbia University in New York City. American physicist Isidor Isaac Rabi was later awarded the Nobel Prize in...
One of the emerging applications of clinical mass spectrometry (MS) is the quantitative detection of small amounts of proteins, biomarkers, or pharmacological compounds, even at low concentrations. Researchers have been able to identify the pharmacokinetic characteristics of medications given in m...
When picking a research topic, consider its feasibility and relevance. Ensure the topic is broad enough for thorough exploration but specific enough to avoid becoming overwhelming. You should also ensure access to resources such as research papers, books, or lab equipment that can support your study...

However, the nature of oxidation, metal dissolution, and interface reactions between the oxide film and the metal surface and all the element-specific effects remain ...
A quenched-solid density functional theory (QSDFT) was used to calculate the pore size distribution (PSD) assuming slit-like pores. The scanning transmission electron microscope experiments were performed in the bight field mode on a JEOL Cs corrected ARM operated at 200 kV equipped with a cold...
While feature-led purchasing tends to address known issues and fulfil identified requirements, it doesn’t necessarily guarantee the comprehensive benefits one might anticipate. Moreover, considering the long-term perspective,Laboratory Information Management Systems (LIMS) and Labo...
