Silica gel particles are commonly used as a stationary phase in high-performance liquid chromatography (HPLC) for several reasons, [13] [14] including: High surface area: Silica gel particles have a high surface area, allowing direct interactions with solutes or after bonding of variety of ligands for versatile interactions with the sample molecules, leading to better separations.
This article is an incomplete list of Financial Accounting Standards Board (FASB) pronouncements, which consist of Statements of Financial Accounting Standards ("SFAS" or simply "FAS"), Statements of Financial Accounting Concepts, Interpretations, Technical Bulletins, and Staff Positions, which together presented rules and guidelines for preparing, presenting, and reporting financial ...
HPLC has many applications in both laboratory and clinical science. It is a common technique used in pharmaceutical development, as it is a dependable way to obtain and ensure product purity. [59] While HPLC can produce extremely high quality (pure) products, it is not always the primary method used in the production of bulk drug materials. [60]
Fast protein liquid chromatography (FPLC) is a form of liquid chromatography that is often used to analyze or purify mixtures of proteins. As in other forms of chromatography, separation is possible because the different components of a mixture have different affinities for two materials, a moving fluid (the mobile phase) and a porous solid (the stationary phase).
The FASB expected the system to reduce the amount of time and effort required to research accounting issues, mitigate the risk of noncompliance with standards through improved usability of the literature, provide accurate information with real-time updates as new standards are released, and assist the FASB with the research efforts required ...
Atmospheric pressure chemical ionization chamber cross section. Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (10 5 Pa), [1] [2] commonly coupled with high-performance liquid chromatography (HPLC).

The FASB expects that the new system will reduce the amount of time and effort required to research an accounting issue, mitigate the risk of noncompliance with standards through improved usability of the literature, provide accurate information with real-time updates as new standards are released, and assist the FASB with the research efforts ...
