MALDITOFMS_ORGANICMILK_7047_C02.csv

Instrument：4800 plus MALDI-TOF/TOF MS（AB Sciex，US），with Dd：YAG Laser Generator（Wave length 355 nm）. 
Mode: Positive ion linear mode. In this mode, signals under 2000 m/z are inaccurate, so they are abandoned in the final dataset.
Laser Intensity: 7500. 
Each spectrum is the sum of 400 scan on the same target. 
Preprocessed by "AB Sciex Data Explorer" software. 

仪器：4800 plus MALDI-TOF/TOF质谱仪（AB Sciex，美国），配备Dd：YAG激光器（波长355 nm）。实验所采用的模式是正离子线性模式，激光强度7500。每张谱图来源于目标点上400次扫描谱图的叠加，数据处理工作由AB Sciex的软件Data Explorer执行。
样本：牛奶原液稀释100倍，与基质SA（浓度为10 mg/mL）混合，滴加至金属靶板，空气中自然待干，检测。
