It might be anticipated that the use of HPLC/MS would improve performance, but the data suggest that between-centre variability is relatively high, probably due to factors such as assay calibration issues and the choice of internal standards. Preliminary data on the introduction of deuterated ...
Chromatography works on the principle that different compounds will have different solubilities and adsorption to the two phases between which they are to be partitioned. Thin Layer Chromatography (TLC) is a solid-liquid technique in which the two phases area solid (stationary phase) and a liquid ...
triggering a vicious cycle of solubility vs binding strength which is counterproductive. Next, the peptide must be reconstituted correctly to undergo HPLC analysis, which upon collection must be dried then dissolved adequately for introduction into T-cell assays. In most cases DMSO or a solvent of ...
Monitoring drug concentrations in the blood is a laboratory tool that can be used to ensure that drug levels are within a therapeutic range. The three main methods to measure blood drug concentrations are bioassay, high-performance liquid chromatography (HPLC) with ultraviolet (UV) fluorescent ...

If an instrument is repaired, it cannot be put back into use until the performance of the instrument has been tested. For example, if the pump seals on an HPLC pump are changed, the only tests that need to be performed are those specific to the repair (for example, pump flow accuracy...
