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.
The Federal Accounting Standards Advisory Board (FASAB) is a United States federal advisory committee whose mission is to improve federal financial reporting through issuing federal financial accounting standards and providing guidance after considering the needs of external and internal users of federal financial information.

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]
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 ...
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). [3]
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 ...
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).
Automated systems will include components normally found on more expensive high performance liquid chromatography (HPLC) systems such as a gradient pump, sample injection ports, a UV detector and a fraction collector to collect the eluent. Typically these automated systems can separate samples from a few milligrams up to an industrial many ...
