High performance liquid chromatography diagram

Figure 7.5 Schematic diagram of a high performance liquid chromatography (HPLC) system. The solvent(s) are pumped through the system, and the sample injected just before the column where separation occurs. Detection is often by UV/visible spectrophotometry at a fixed wavelength.

Caprioli and Lin first described this method for the characterization of penicillin G in 1990 [19]. A diagram of the microdialysis/cfFAB experimental setup used is shown in Fig. 8. Dialysate was allowed to collect in a 20- dL sampling loop via syringe pump. After collection, the injection valve was switched and a high-performance liquid chromatography pump was used to deliver the microdialysis sample to the mass spectrometer. Mass spectra of penicillin from both a standard and an in vivo microdialysis sample (shown in Fig. 9) compare well.

FIGURE 28 1 Selection of LC modes. Methods can be chosen based on solubility and molecular mass. In most cases for non-ionic small molecules (jW < 2000), reversed-phase methods are suitable. Techniques toward the bottom of the diagram are best suited for species of high molecular mass (.it > 2000). (Adapted from High Performance Liquid Chromatography. 2nd ed.. S. Lindsay and J.
