What is spectroscopy? What are the different methods of spectroscopy? What is IR spectroscopy and what is it used for? Explain what a flame test has to do with spectroscopy. What is the basic principle of IR spectroscopy? What is mass spectroscopy in terms of chemistry? What is its ...
Tunable laser spectroscopy is a technique that can measure the absorbance spectrum; this information can then be used to identify the molecules in the sample and determine concentrations. The principle behind tunable laser spectroscopy is that when a molecule absorbs light, its energy levels become ...
Figure2depicts a generic view on the work-up of a patient suspected with cancer: the patient presents with a suspicion of cancer and is referred for an imaging examination. Here, imaging denotes the acquisition of non-invasive visual data of extended ranges or volumes of the subject. Convention...
1H-NMR spectroscopy metabolomics coupled to Principle Component Analysis (PCA) and HPTLC methods were used for the phytochemical and metabolomics investigation of 72 turmeric samples, including crude powders, intermediate products from different manufacturing stages and commercial products obtained from health...
Metabolites that were detected in urine samples by NMR spectroscopy were linked to the DGGE fingerprint using multivariate analysis. By way of proof of principle, Li et al. linked the well-characterized species Faecalibacterium prausnitzii with 3-aminoisobutyrate, one of its known metabolites. The ...
What is Diatropic? noun.a response of plants or parts of plants to an external stimulusby growing at right angles to the direction of the stimulus. What is NMR useful in predicting aromaticity? Aromatic ring currents are relevant to NMR spectroscopy, as they dramatically influence thechemical ...
A central pillar of the scientific process is to study how cells respond to controlled changes in specific factors. This hypothesis-driven, reductionist approach is necessary for ranking the various possible factors that influence cancer progression. However, this strategy raises the critical question of...
The Vacuum System - This is a component of the microscope that helps minimize collision frequency of electrons with gas atoms. As such, it enhances the efficiency of the electron gunHow the Cryo-EM WorksTransmission electron microscopes use the same working principle as the ordinary light microscop...
Qualitative analysis is a chemical procedure through which the chemical composition of an unknown sample can be estimated. The information about ions, atoms, or functional groups can be determined from this analysis, but their quantity can't be counted....
Question: Where is definition of raw data contained in EU GMP? Answer: Nowhere! Question: What is the definition of raw data in the US GMP? Answer: There isn’t one! The problem is when a new term is introduced into a regulated environment there should be a definition of that term so...
