    • This invention relates to a system for and a method of filtering at least a part of gas chromatography-mass spectrometry data, the method comprising: providing gas chromatography-mass spectrometry data (301) for a gas mixture comprising data representing one or more gas chromatography elution peaks obtained for at least one sample, and filtering the gas chromatography-mass spectrometry data (301) to reduce the amount of data, wherein the filtering comprises taking into account predetermined data representing one or more elution peaks previously determined to be false positives (305) and/or predetermined data representing one or elution peaks previously determined to be true positives (304). In this way, unreliable elution peaks are removed in an expedient manner reducing the amount of data e.g. used for a later alignment process speeding up the processing time and also improving the data quality.

    • 本发明涉及一种用于过滤气相色谱 - 质谱数据的至少一部分的系统和方法,所述方法包括:提供用于气体混合物的气相色谱 - 质谱数据(301),其包含表示一种或多种气相色谱 对至少一个样品获得的洗脱峰,并过滤气相色谱 - 质谱数据(301)以减少数据量,其中过滤包括考虑预先确定为假阳性的一个或多个洗脱峰的预定数据( 305)和/或表示先前确定为真阳性的一个或洗脱峰的预定数据(304)。 以这种方式,以方便的方式去除不可靠的洗脱峰,从而减少数据量。 用于稍后的校准过程,加快了处理时间,并提高了数据质量。 图2
