应用激光解吸离子化／傅里叶变换质谱法进行双氯芬酸钾的正负离子质谱研究，由正负离子质谱中准分子离子及重要碎片离子的准确质量和元素组成，获取其结构信息并推测其可能的质谱裂解途径
The positive and negative ion mass spectra of diclofenac potassium were studied by laser desorption ionization / Fourier transform mass spectrometry. The exact mass and elemental composition of the quasi- and major fragment ions in the anions and anions were obtained, and the structure information was obtained and the possible mass spectra Cleavage route
