MS-MS 對照
Tandem mass spectrometry controls complementary to our MS/MS isotope standards. In most cases, studies using tandem mass spectrometry require the presence of controls against which the reliability of the measurements will be checked. This category contains compounds that can be used as controls in MS/MS quantification experiments.
