This second column in a two-part series on gas cylinder safety presents safe procedures for installing, using, and replacing gas cylinders and pressure regulators.

Continued from last month, this month's column discusses specially designed columns for use in highly aqueous environments. Many of these columns also can be used as regular reversed-phase columns for a range of mobile phases.

Dolan discusses some of the challenges of separating small peaks from large ones and gives some pointers on how to obtain a separation.

The authors evaluate the performance of multiplexed 96-lane CE with laser-induced fluorescence detection for high-throughput separation–based assays using fluorescein isothiocyanate as a model compound and fluorescein as an internal standard.
