| Fast injection also simplifies quantitation by enabling the use of external standards. |
| After mixing and centrifugation, aliquots of the acetic acid phase were injected onto a Chromatographic system for quantitation of catecholamines. |
| A radioactive label within the DNA permits direct visualization and quantitation of the results. |
| They therefore need to be separated chromatographically prior to quantitation. |
| The neat DNA was read spectrophotometrically at 260 nm for the quantitation of the virus. |
| Plasma concentrations are less than dose proportional in baboons, and in rats and marmoset levels are too low for reliable quantitation. |
