Spark source mass spectrometry (SSMS) and atomic absorption spectrometry (AAS) have played important roles as powerful analytical tools. Both these techniques have undergone significant improvements since the late fifties in instrumentation and methodology leading to their application in various branches of science and te chnology. These techniques can be regarded as complementary techniques in...

Digital watermarking is widely used as one of the techniques to identify ownership and protect copyrights of digital images. The watermark inserted may be visible or invisible. A Visible watermark, which is nothing but a digital pattern logo or trademark, directly convey ownership information on the media, while invisible watermarks do it indirectly after being extracted with the help of extrac...

In natural-product drug discovery, finding new compounds is the main task, and thus fast dereplication of known compounds is essential. This is usually performed by manual liquid chromatography-ultraviolet (LC-UV) or visible light-mass spectroscopy (Vis-MS) interpretation of detected peaks, often assisted by automated identification of previously identified compounds. We used a 15 min high-perf...

Mass spectrometry (MS) offers a sensitive, reliable, and highly accurate method for measurement of isotopic labeling, which is required for generating comprehensive flux maps using metabolic flux analysis (MFA). We present protocols for assessing isotope labeling in a wide range of biochemical species, including proteinogenic amino acids, free organic and amino acids, sugar phosphates, lipids, ...
