An interesting comparison of separations that can be obtained by capillary electrochromatography, capillary electrophoresis, and high-performance chromatography has been published [192]. 

It can be argued that modern, high performance chromatography began with the publication of Martin and James s paper on gas chromatography in 1952. It is certainly true that their publication on the use of a gas as a mobile phase in the separation of volatile fatty acids initiated the research that has resulted in the wisespread use and popularity of chromatography. 

More precise testing is made by column, gas or high performance chromatography equipment, or by use of magnetic resonance or an electron microscope. These methods are all quite expensive and necessitate equipment rarely available outside of industry, universities and crime labs.

As an example, consider a chromatogram in which a number of compounds are detected with different elution times, at the same time as a their spectra (such as UV or mass spectra) are recorded. Coupled chromatography, such as high-performance chromatography-diode array detection (HPLC-DAD) or liquid chromatography-mass spectrometry (LC-MS), is increasingly common in modern laboratories, and represents a rich source of multivariate data. These data can be represented as a matrix as in Figure 4.3.

This concept was not taken into consideration when the era of high-pressure stainless steel columns was introduced. At that time fluid distribution by high-pressure drop, as explained above, was dominant. Only more recently, with the advent of low-pressure high-performance chromatography, has the focus been more and more on...

In methyl parathion resistant tobacco budworms, larvae were treated, lots of 10 were homogenized, and methyl parathion was recovered by solid phase extraction and analyzed by reversed phase high performance chromatography with ultraviolet detection. Unexpectedly, the resistant strains lost methyl parathion at a lesser rate than the susceptible Florence 1987 strain (Figure 3). Independently, T. Konno et. al. have found a slower bioactivation of [l4C]-methyl parathion in another resistant strain of this pest (791.
