Nondestructive testing method for components of bagged injection

The invention relates to the technical field of near-infrared detection, in particular to a nondestructive detection method for components of bagged injection, which comprises the following steps: selecting a bagged injection sample in advance; collecting the spectrum of the selected bagged injection sample by using a portable optical fiber near-infrared instrument; respectively carrying out component content detection on the selected bagged injection samples by adopting a standard method in national standard or pharmacopoeia; establishing a corresponding near-infrared quantitative model; the method comprises the following steps: taking a bagged injection sample to be detected, and collecting by using a portable optical fiber near-infrared instrument; and performing component detection on the to-be-detected bagged injection sample by adopting a national standard or pharmacopoeia standard method, and comparing the results of the standard method and the near-infrared rapid nondestructive method until the detect
