| After mixing and centrifugation, aliquots of the acetic acid phase were injected onto a Chromatographic system for quantitation of catecholamines. |
| In addition, a detector is frequently placed on-line after the column for either structure analysis or quantitation or both. |
| The neat DNA was read spectrophotometrically at 260 nm for the quantitation of the virus. |
| Fast injection also simplifies quantitation by enabling the use of external standards. |
| Lower limits of quantitation can be obtained by increasing the deposition time. |
| They therefore need to be separated chromatographically prior to quantitation. |
