Are you still embarrassed by the emperor? Excellent? (TA in the contact station) Yes, but the baseline noise is high and there are many peak interferences. It is difficult to analyze these data. If there is no better choice, just use him to do it. The chromatographic conditions are better. Chi Haijun ion trap is not as quantitative as quadrupole, and the linear range may be smaller, but it is ok if you make a standard curve suitable for sample concentration. The accuracy of Liumingge (in-station contact TA) ion trap is almost poor, and it has its own characteristics compared with quadrupole chiraler (in-station contact TA) ion trap: 1, sometimes there is quality discrimination; 2. It should be no problem to do secondary quantification; After doing it, it was found that the accuracy was poor and the circuit was not bad (using SRM). Slender Wang (contact TA in the station) Yes, the quantitative measurement is almost bad, and the stability is not good. Compared with liquid phase, it is still much more sensitive, but it can be quantified. You can also send a piece of paper yjywei (conTAct ta in the station). I also want to know, and I paid attention to Xiao Xixie 4 16 (contact TA in the station). Wjlcc (in-station contact ta) can, but the linearity is not ideal. chiraler (in-station contact ta) quality discrimination: commonly known as quality contempt. For different types of mass spectra, the corresponding detection quality ranges are different. Even the same instrument has different reactions to the same sample with different quality, because its corresponding quality range is despised and insensitive. For example, quadrupole discriminates against mass. The signal intensity of large samples with the same concentration is lower than that of small samples with the same concentration. Or, after the same sample enters the quadrupole, the signal intensity in the large mass region is less than that in the small mass region. Ion traps, on the other hand, discriminate against small masses and respond better to large masses. Quality discrimination: commonly known as quality contempt. For different types of mass spectra, the corresponding detection quality ranges are different.
