- 論文の詳細を見る
Metastable argon atoms at atmospheric pressure were used to ionize organic compounds and an emitter for field desorption was used as a sample holder. The effect of electric field, temperature and additives were investigated for involatile compounds like nucleosides. High voltage applied to the emitter and a matrix increased the abundance of MH+ ions significantly and long-lasting good mass spectra were obtained. A needle emitter was better than a silicon emitter and Nujol (liquid paraffin) as a matrix was better than glycerol for thermolabile compounds having small proton affinities such as guanosine and creatine.
