【摘要】 本文所述的四极质谱计微型数据系统是针对各种国产四极质谱计而研制的。它由TP801单板机、微型打印机、A/D和D/A接口板、电源组成。它具有多道选择扫描、平滑、扣本底、谱峰增益控制、峰识别及计算、质量定标、计算分辨率、自动定时监测等功能,在打印机上给出各谱峰的质量数、强度、归一化强度、分辨率,并画出谱图、棒状谱图及某些选定谱峰随时间变化的曲线等。该系统配置简单、工作稳定、成本低、与质谱计连结方便。更多还原

【Abstract】 The mentioned micro data system was designed for various quadrupole spectrometer. It consist of a Single Board Computer TP801, a microprinter, A/D and D/A interface and power suppiy, it performs many functions, such as selectable multi-channel scanning, digital smoothing, background substraeting, peak recognization, standard mass calibration, peak-gain control, resolusion calculation, antomatic monitoring, et al, The related data about mass, intensity, relative intensity and resolution can be given by the microprinter in the list table. It can also print graphy, bargraphy and plots of peak intensity via tim.This data system possesses advantages of being simple, low-cost, stable and convenient to be with quadrupole spectrometer.更多还原
