Microwave digestion vessels are internal consumables of microwave digestion instruments. Generally, microwave digestion instruments include inner liners and vessel sleeves. The inner liners are divided into inner plugs, lids, and vessel bodies. Some microwave inner liners are directly lids and vesse

Impingers are small bottles used with an air sample pump to collect airborne hazards into designated collection liquids for analysis. For personal exposure measurement the impinger mounts in a holster accessory near the breathing zone. For area monitoring the impinger is mounted on the side of a pum

Column chromatography, also known as adsorption chromatography. A column is first filled with an insoluble matrix to form a stationary phase, the sample is added to the column and then eluted with a special solvent, and the solvent forms the mobile phase. During the process of elution of the sample
