Description
Heptafluorobutyric acid anhydride serves as a high-purity derivatisation reagent for gas chromatography procedures. This compound possesses the empirical formula C₈F₁₄O₃ together with a minimum purity of 97 %. It exhibits a molar mass of 410.06 g/mol, density of 1.653 g/cm³ and boiling point between 108 and 109 °C. The reagent is packaged in 5 g glass containers suitable for precise laboratory applications. Its physical characteristics support reliable performance in analytical workflows that require consistent derivatisation results. The material from manufacturer Carl ROTH maintains quality suitable for chromatography laboratories handling demanding sample preparation. Applications focus on GC methods where reagent purity directly influences analytical accuracy. The product enables efficient conversion of analytes while minimising interference during separation and detection. Laboratories value the compound’s stability and defined specifications for reproducible outcomes across multiple runs, especially when analysing polar compounds that require enhanced volatility and thermal stability. Analysts routinely apply the anhydride to improve peak shapes and detection limits in trace-level environmental or pharmaceutical samples.

Questions about Heptafluorobutyric acid anhydride, min. 97 %, for GC, 5 g, glass
What is this article?
Heptafluorobutyric acid anhydride, min. 97 %, for GC, 5 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in GC liners, septa, syringes & accessories, inside GC columns & accessories, in Chromatography equipment.
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.
