Abstract Acid Red 73 (CI 27290) is a prohibited component in cosmetics, particularly hair color formulations. The purpose of this investigation to discover the coloring additive cosmetic dye sulfonated azo that manufactured be more hazardous than other colors and damaging body. Based on variations polarity solubility, separated from sample matrix identified using High Performance Liquid Chromat...

Liquid Chromatography Mass Spectrometry (LC-MS) is a powerful method for sensitive detection and quantification of proteins and peptides in complex biological fluids like serum. LC-MS produces complex data sets, consisting of some hundreds of millions of data points per sample at a resolution of 0.1 amu in the m/z domain and 7000 data points in the time domain. However, the detection of the low...

Abstract. Environmental samples typically contain hundreds or thousands of unique organic compounds, and even minor components may provide valuable insight into their sources transformations. To understand atmospheric processes, individual are frequently identified quantified using gas chromatography–mass spectrometry. However, due to the complexity variable nature such data, data reduction is ...
