Abstract: | "It is highly desirable to screen for a large variety of organic compounds in water. Ultra-high performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) can analyse semi-polar to polar organic compounds in tap and mineral water. The use of UHPLC-HRMS is well consolidated for lipidomic, metabolomic and proteomic studies; based on the detection of a very large number of compounds of a variety of organic functions. Water analysis is usually performed by gas chromatography -mass spectrometry (GC-MS) techniques that are efficient for volatile organic compounds. Therefore the use of UHPLC-HRMS as a screening method based on an untargeted omic approach for the analysis of organic compounds with polar functional groups is welcome. This UHPLC-HRMS method was developed and tested with tap water and mineral water. We analysed six different brands of mineral water from France, Spain, Norway and Brazil and tap water from Jandaia do Sul, PR, Brazil to test the approach and demonstrate how UHPLC-HRMS may be used as a screening method for water quality. Forty-seven different ions were observed in tap and mineral water and their intensities were submitted to principal component analysis (PCA) evaluation. Fifteen ions were identified comparing the mass spectrometric results to metabolomic and lipidomic libraries" |
