Abstract: The present disclosure relates to a method for detecting DTPA content in ADC by LC-MS/MS. The samples are derivatized with Fe3+ under a weak alkaline derivatization condition, and a weak alkaline mobile phase is used, without need for addition of ion-pair reagents. This method has the characteristics of high efficiency, high stability and strong durability, and can well make up for the defects of few DTPA detection methods and complicated operations in the prior art.

Abstract: Aluminum alloy with preferred mechanical property and preferred electrical and thermal conductivity is provided by a manufacturing method. The aluminum alloy consists of Si about 0.33˜0.37 wt %, Mg about 0.45˜0.55 wt %, and Fe about 0.07˜0.15 wt %, and the rest weight of the aluminum alloy is Al. A ratio of Mg to a different between Al and one third Fe is ranged between 1.45˜1.75.
