Mass spectra of α-tocopherol and its oxidative products

Centroid mass spectra data for α-Tocopherol and its oxidative products separated by supercritical fluid extraction (SFE)/supercritical fluid chromatography (SFC)-proton transfer reaction (PTR) ionization time-of-flight (TOF) mass spectrometry.  SFE was carried out at 40°C 25 MPa of CO2.  One μL portion of extracts in the fluid was injected into an SFC system.  SFC was carried out at 40°C, 30 MPa of CO2, 1.0 mL/min isobaric using L-column3 (2.1 mm x 100 mm, 3μm).  The data file 'Not incubated (83.1)-0024-83.csv' and the 'Incubated (82.3 s)-82.3.csv' are both the mass spectrum of α-tocopherol obtained from non-incubated and incubated samples, respectively.   The number in a pair of parenthesis indicates the retention time for the data on an incubated α-tocopherol sample.

α-生育酚及其氧化产物通过超临界流体提取（SFE）/超临界流体色谱（SFC）-质子转移反应（PTR）飞行时间（TOF）质谱仪分离后的质心质量光谱数据。超临界流体提取在40°C、25 MPa的二氧化碳下进行。将1 μL的提取液注入SFC系统中。SFC在40°C、30 MPa的二氧化碳、1.0 mL/min的等压条件下，使用L-column3（2.1 mm x 100 mm，3μm）柱进行。数据文件'未孵育（83.1）-0024-83.csv'和'孵育（82.3 s）-82.3.csv'分别代表非孵育和孵育样品获得的α-生育酚质量光谱。括号中的数字表示孵育α-生育酚样品上数据的保留时间。
