WebThe expansion of the Sigma-Aldrich portfolio of acyl-L-carnitine standards has been successfully achieved by a generalized synthetic approach. L-Carnitine hydrochloride was added to a mixture of the appropriate carboxylic acid and a slight molar excess of acid chloride. The reaction mixture was kept at an elevated temperature until TLC analysis ... WebHILIC-RPLC (or vice versa) is the most orthogonal combination of liquid separation techniques when orthogonality is defined as the coverage fraction of a 2D separation … WebThe separation was achieved in HILIC mode by using the Accucore 150 Amide HILIC column. The column was operated by the Vanquish Flex Quaternary UHPLC system (Table 1 and Table 2). Detection was performed using the Thermo Scientific ™ Vanquish Diode Array Detector HL with a LightPipe™ 10 mm standard flow including in a sentence grammar
