the data are normalized by assigning the most intense peak (denoted as base peak) a value of 100.Other peaks are reported as percentages of the base peak.A very good general survey for interpreting mass spectral data is given by Silverstein et al.1810.6.1 Initial Steps in Elucidation of a Mas[r]
Motion Study, also known as motion research, element analysis, or work study, its main content is seeking the most economical and effective working method through a variety of analytical methods. It is an effective way to study and formulate correct and reasonable motion to shorten hours and improve[r]
Unlike HPLC, where the analyte is eluted continuously with mobile phase,and collected when the detected signal appears, the analytes collected inSPE process have no monitoring signal. Therefore, no matter what kind ofmechanism, the retention of the interested analytes on the sorbents has tobe very s[r]
