29. While carrier and sample solvents were carefully degassed, some oxygen redissolved during sample preparation and was detected by the sensitive model 441 absorbance detector operating at 254 nm. This signal from dissolved oxygen can be avoided by using a refractive index detector or by preparing the sample solutions under a protective atmosphere.
