Chemistry of zirconia and its use in chromatography.
The purpose of this review is to shed some light on the complex properties of zirconia's surface chemistry in order to better understand its behaviour under chromatographic conditions and shows that the main difficulty in achieving a wider variety of applications is probably the lack of knowledge and poor understanding of zIRconia’s surface chemistry.

Fast, comprehensive two-dimensional liquid chromatography.
This report is deliberately focused on the issues involved in doing fast 2DLC by means of elevating the column temperature; however, many issues of broader applicability will be discussed. Expand
A study of the critical criteria for analyte stability in high-temperature liquid chromatography.
A study of the ability of a number of pharmaceuticals to withstand superambient temperatures on the time scale of fast separations and proposes criteria by which a particular analyte may be rejected as a candidate for high-temperature analysis, and demonstrates that complex molecules are amenable to quantitation.

Analysis of four-way two-dimensional liquid chromatography-diode array data: application to metabolomics.
Chemometric methods are applied and adapted to the analysis of maize seedling digests, focusing on compounds related to the biosynthetic pathways of indole-3-acetic acid, the primary growth regulator in plants, to demonstrate the quantitative potential of multivariate curve resolution methods.

  • 19 March 2005
This work describes high-temperature, ultrafast HPLC conditions, along with the instrument modifications needed to reduce the analysis time of each complete second-dimension gradient separation to tens of seconds, and generates a high peak capacity characteristic of comprehensive 2D-LC in a relatively shorter analysis time.
