Retention index standards for liquid chromatography |
| 摘要 |
A homologous series of neutrally charged compounds having at least one functional group bearing a positive charge and at least one functional group bearing a negative charge are advantageous retention index standards for liquid chromatography, especially for liquid chromatography-mass spectrometry (LC-MS) methods, more especially for LC-MS methods employing electrospray (ESI) or atmospheric pressure chemical ionization (APCI) ionization systems. |

1. A series of retention index standards for use in liquid chromatography, the series of retention index standards comprising two or more neutrally charged homologous compounds, each compound comprising at least one functional group bearing a positive charge and at least one functional group bearing a negative charge and each compound comprising an alkyl group having a different chain length, wherein each compound in the series has Formula (II): where n is an integer from 0 to 23, and where each compound in the series has a different value for n. |
