High Performance Liquid Chromatography (HPLC) is an analysis technique used for separation and quantification of small molecules and polymers. HPLC is the method of choice for testing complex mixtures containing non-volatile and semi-volatile organic compounds such as polymer additives , active pharmaceutical ingredients (API’s), and impurities.
Mar 11, 2019 · HPLC injection is a technique used to load the sample into the HPLC system. This process is done using a specially designed injection system which is a separate and prominent part of the HPLC system. The most popular injector is the rheodyne injector. The injection is done manually by an external syringe or autoinjector.

The minimum required volume in the sample vial is vary instrument to instrument and is completely based on the auto sampler, in particular how long needle will insert into the sample vials.
High-performance liquid chromatography, or HPLC, is a highly versatile technique that separates components of a liquid mixture based on their different interactions with a stationary phase. HPLC is an adaptation of column chromatography. In column chromatography, a column is packed with micro-scale beads called the stationary phase.
Dec 17, 2015 · “The choice of solvents that can dissolve a polymer is typically very limited, compared to small molecules, and limits the type of HPLC method you can use. Also, polymers contain a distribution of chain lengths, which often will result in multiple peaks or a very broad peak during the HPLC separation.
