Questions about n-Valeric acid methyl ester ROTICHROM, 100 mg, verre
What is this article?
n-Valeric acid methyl ester ROTICHROM, 100 mg, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Liners GC, septa, seringues & accessoires, inside Colonnes GC & accessoires, in Chromatographie.
A GC liner is the glass sleeve of the injector, and it collects the non-volatile residue. Its geometry, straight, gooseneck, with or without wool, belongs to a method. Septa and syringes are the other parts that leak. A liner for one injector model does not fit another.
A GC capillary column is a long open tube with a stationary phase coated on the wall. The sample is a vapour, carried by gas. The phase, the film thickness, the length and the internal diameter decide which compounds separate and how long it takes. A liner is the glass sleeve in the injector. It is a consumable: it collects the non-volatile dirt. The septum and the syringe are the other parts that leak or shed. Compound identity sits on PubChem under IUPAC names.
