The ability to rapidly screen stationary phases through column-switching capabilities provides significantly greater efficiency in method development than was previously possible. The approach does require some additional hardware and software. And, while such capabilities may limit the ability to expand one's literary knowledge during excessive months in the laboratory developing separation methods, real progress to key decision points for method optimization can be realized instead.

GC CONNECTIONS
Two GC instruments running the same method in the same laboratory might disagree somewhat about the same sample or standard, and two instruments in different laboratories might disagree by a larger margin. This instalment explores reasons for such observations and expectations for how well instruments might match up.
