Hyphenated Techniques
The use of mass spectrometry detection with separation techniques such as liquid and gas chromatography has provided analysts with a much higher degree of specificity than that obtained using a single technique or instrument. Participants in this discussion of hyphenated techniques in chromatography are
Staff scientists from Almsco; Monty Benefiel, Ken Miller, and Ed McCurdy of Agilent Technologies; Jim Edwards, Shona McSheehy, and Sergio Guazzotti of Thermo Fisher Scientific; and Ann Hoffman of Torion Technologies.

Application Note |
A major improvement in preparative chiral column performance
has been achieved by adapting axial compression to manufacture
Lux™ chiral preparative columns. This paper demonstrates the
advantages of combining the new Lux media and Axia™ packing
technology to produce high performance stable preparative
chiral columns. This new process produces preparative columns
packed with 5 µm media with the same efficiency (plates per
meter) in prep columns as found in analytical columns and peak
symmetry independent of column length and internal diameter.
