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。
The quadrupole mass spectrometer mini-data system described in this paper is developed for various domestic quadrupole mass spectrometers. It consists of TP801 single-board machine, micro-printer, A / D and D / A interface board, power supply. It has multi-channel selection scan, smooth, buckle background, peak gain control, peak identification and calculation, quality calibration, calculation resolution, automatic timing monitoring and other functions, the printer gives the quality of each peak number, intensity , Normalized intensity, resolution, and draw the spectrum, rod shape and some selected peaks with the time curve of the curve. The system configuration is simple, stable, low cost, easy connection with the mass spectrometer.
