Interference due to jelly. (a) Spectrum showing resonance from jelly. (b) Spectrum of mini-bronchoalveolar lavage (mBAL) fluid dominated by resonance from jelly. (c) Spectrum showing resonance originating from small metabolites present inside mBAL fluid (control). (d) Various small molecular weight metabolites present inside mBAL fluid of an acute respiratory distress syndrome patient. 1, isoleucine, valine and leucine; 2, ethanol; 3, lactate/threonine; 4, alanine; 5, arginine and lysine; 6, acetate; 7, glutamate; 8, succinate; 9, pyruate; 10, glutamine; 11, aspartate; 12, asparagine; 13, creatine and lysine; 14, histidine; 15, betaine; 16, taurine; 17, choline; 18, glycine; 19, lactate; 20, threonine; 21, β-glucose; 22, uracil/urea; 23, fumaric acid; 24 and 26, tyrosine; 25 and 29, histidine; 27, phenylalanine; 28, uracil; 30, adenine; 31, formate.
