Thin layer chromatography (TLC) is one of the easiest and most versatile methods of doing this because of its low cost, simplici In many experiments, it is important to be able to separate a mixture into its chemical components in order to isolate one compound or to assess the purity of the mixture.
Apparently they were into the chromatography business before Aijiren spun off, so not surprising that there's some vials with their logo. OP, could be that your vial is just something that's been floating around the lab forever, and whatever instrument it was originally associated with has long since passed on. A vial is a vial after all.
Background. Thin layer chromatography (TLC) is used routinely in the laboratory to both monitor reactions and analyse the purity of samples. TLC is a type of adsorption chromatography, and the most common substrates used for the stationary phases in the lab, are silica (SiO 2) and alumina (Al 2 O 3).
For laboratories overwhelmed with solvent disposal and time-consuming solvent cleanup, supercritical fluid chromatography (SFC) is a beneficial alternative to purification and analytical applications. Considered a leading "green" purification technology, SFC systems from Aijiren Technology are used to separate and isolate chiral and achiral chemical

Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including autosampler vials, general-purpose vials, and vial accessories for sample collection, storage, and
Gas Chromatography Let’s begin with an example problem: SPME head space analysis of pesticides in tea and follow-up analysis by high speed GC. Anal Chim. Acta 611 (2008) 163 Samples in 10mL sealed glass vials were placed in the MPS-2 autosampler for HS-SPME extraction. Extracted compounds were thermally desorbed from the fiber
Danner Process. Tubing sizes from 1.6mm to 66.5mm diameter. Drawing rates of up to 400m a minute for the smaller sizes. Glass flows from a furnace fore hearth in the form of a ribbon, which falls on to the upper end of an inclined refractory sleeve, carried on a rotating hollow shaft or blowpipe.
Analyze various candies, foods, tea extracts and pen ink while comparing and contrasting paper chromatography and TLC results to reference materials. Teach students molecular polarity and intermolecular forces. Ideal for AP Chemistry, Chemistry I or II, or Honors Chemistry
