| Item | Value for Various Detection Methods | ||
|---|---|---|---|
| UV at 220 nm | MS, + Ion (APCI) | MS, − Ion (APCI) | |
| No.b | 22 | 23 | 20 |
| Mean | 1.1 | 1.3 | 0.5 |
| Standard Deviation | 0.7 | 1.0 | 0.2 |
| % RSD | 60% | 75% | 43% |
↵a Abbreviations: LC, liquid chromatography; UV, ultraviolet; MS, + Ion (APCI), mass spectrometry, positive ion, atmospheric pressure chemical ionization; MS, − Ion (APCI), mass spectrometry, negative ion, atmospheric pressure chemical ionization; RSD, relative standard deviation.
↵b The total number of analytes investigated in this article was 32. Thus mutliple analytes produced no response in one or more of the detection methods.
