Peak 3 was identified from the coincidence of t R and the mass spectra with the standard boldenone (see next drug). The unchanged quindenione was not excreted as such but was rapidly metabolized to boldenone.

A miniaturized continuous gradient elution system with variable gradient profile was designed. A retention time reproducibility below 1% was achieved. The system was applied to the separation of phenolic compounds with a wide range of polarities.
A miniaturized continuous gradient elution system was designed for work with packed capillary columns. The retention reproducibility achieved is adequate for many practical applications.
## Abstract A dryβpacking method has been developed which enables the preparation of packed capillary columns for micro HPLC from 250 ΞΌm i.d. tubing and 5 ΞΌm packing materials. Pressurized gases, such as hydrogen and argon, were used to transport the packing media, and ethanol or methanol were used
A simple, easy-to assemble gradient generator for capillary electrochromatography is described. Using a homologous mixture of alkylphenones and a macroporous polyacrylic separation matrix, we demonstrate the feasibility of either stepwise or continuous gradients to be performed in a reproducible man
