ESI-ToF MS 方法翻译?亲们,请问下面这段话是什么意思?可以帮忙翻译一下吗?因为都是专业词汇,看不懂啊,多谢了!ESI-ToF MS:EPS have been analyzed in??negative-ion mode on a QqTOF system (Ultima, Waters). Probe: 3 kV, cone 50 V, Rf lens 25 V and collision: 10V, up to 25V for MS/MS. Samples heve been dissolved at a concentration of 2 mg.mL-1 in water/methanol 1:1 with 0.1 % ammonia. The injection has been carried out with a flow rate of 7 µL.min-1. The scan range has been established between m/z 500 and m/z 2500 in 2 sec with 0.2 sec interscan delay. The spectra have been deconvoluted using Max Ent 3.NMR:NMR spectra have been recorded at 303 K, at 500 MHz (1H) and 125.75 MHz (13C) using a cryoprobe.The spectra were layed out using MestResNova.查看更多4个回答 . 3人已关注
