I. Basic Properties of Sodium Hexafluorosilicate Sodium hexafluorosilicate is a white crystalline powder that remains stable at room temperature. It can mix with water, producing hexafluorosilicate ions and sodium ions. The molecular formula of sodium hexafluorosilicate is Na2SiF6·6H2O, with a relative molecular mass of 264.08. It has a density of...

Compared to many sophisticated analytical instruments in the laboratory, vials may be small, but their proper selection and usage play a crucial role in experiment efficiency, processes, and data accuracy. Incorrect choices of vials can lead to various issues, including poor sealing causing analyte volatilization, chromatographic peaks due to solvent-septa...

The use of laboratory reagents and consumables is an indispensable part of scientific research, and employing correct usage methods and precautions ensures experiment accuracy and safety. Below are recommendations on how to use laboratory reagents and consumables to ensure experiment safety: 1. Read Labels and Manuals: Before using laboratory reagents...

Methods for Cleaning Headspace Vials in Laboratories Headspace vials, primarily made of glass with minimal use of plastic, are commonly reused in laboratories to reduce costs and environmental impact associated with single-use vials. The typical cleaning methods involve the use of laundry detergent, cleaning agents, organic solvents, and acidic or...

Headspace vials are common consumables used in gas phase experiments, especially in gas chromatography (GC) analyses. These vials are typically used to prepare headspace samples containing the sample, dilution solvent, matrix modifier, and headspace. In simple terms, laboratory bottles used for headspace analysis are referred to as headspace vials. These...

Thin-Layer Chromatography (TLC) is a highly useful technique for monitoring reactions and selecting suitable solvents in column chromatography. Common stationary phases for TLC include alumina or silica gel, while the mobile phase is a polar solvent. The procedure involves spotting the reaction mixture on a thin plate and utilizing capillary...
