Lab 2: High Performance Liquid Chromatography - Chemistry

Sep 8, 2022 · HPLC can be performed with fixed or variable solvent composition. When the solvent polarity is fixed, it is known as an isocratic run. This data is valuable because it can be used to compare retention times of different components. This method only works when the components have unique retention times under that condition.

Autosampler Vials, Inserts, and Closures | Fisher Scientific

Autosampler vials are usually made from clear or amber glass, both of which are highly inert. Amber glass helps protect more sensitive samples from exposure to UV light and radiation. Vial inserts are used to reduce the capacity of the vial to accommodate smaller samples. Typically 150 to 400µL in volume, they may be made of glass, plastic, or

One of the most important factors are vial and septa cleanliness, which introduces contamination peaks. Ghost peaks are introduced by analyte degradation that can be triggered by significant pH changes in the diluent. In this chromatogram, the top shows normal behavior, and the bottom chromatogram shows ghost peaks.
