A study is presented on the reproducibility of mass spectral profiles whole bacterium E. coli resulting from laser sampling at different regions within and between matrix-assisted desorption ionization (MALDI) samples deposited onto plate. Samples were prepared with deposition methods using MALDI matrices. The three most common matrices used in MALDI-mass spectrometry (MS) bacteria profiling, α-cyano-4-hydroxycinnamic acid (CHCA), sinapinic (SA), ferulic (FA), compared this along two...
A novel ligand N-4-hydroxyacetophenone isonicotinoyl hydrazone and its manganese(II) nickel(II) metal complexes have been synthesized. The synthesized Schiff base characterized by physical state determination, melting point solubility measurements in different solvents, infrared, proton nuclear magnetic resonance, mass spectrometric powder X-ray spectroscopic techniques. thermal properties of the prepared compounds were obtained from TG/DTG measurements. On basis analytical techniques, was...
Iron(II) and manganese(II) complexes of N'-(1-(pyridin-2-yl)ethylidene)nicotinohydrazide (LH) have been synthesized characterized by elemental analysis, IR, 1H NMR spectroscopy. The crystal structure the ligand has determined single X-ray diffraction electronic spectroscopic techniques. Crystal data for LH, C13H12N4O: Orthorhombic, space group Pbcn (no. 60), a = 18.0824(3) Å, b 7.86555(14) c 16.1614(3) V 2298.60(7) Å3, Z 8, T 103 K, μ(Mo Kα) 0.093 mm-1, Dcalc 1.388 g/cm3, 36729 reflections...
