For laboratories and research institutions that rely on precise and accurate mass spectrometry data, the selection of the right calibrant is paramount. Among the various compounds used for this purpose, Perfluorotributylamine (CAS 311-89-7) stands out due to its unique properties that make it an exceptional choice for gas chromatography-mass spectrometry (GC-MS) applications. As a leading manufacturer and supplier, we understand the critical role this chemical plays in ensuring the reliability of analytical results.

Perfluorotributylamine, often referred to by its acronym PFTBA or the trade name FC-43, is a perfluorinated amine. Its molecular structure, N(CF2CF2CF2CF3)3, is characterized by a central nitrogen atom bonded to three perfluorobutyl groups. This complete fluorination imbues the molecule with remarkable stability, low reactivity, and a distinctive fragmentation pattern when subjected to electron ionization in a mass spectrometer. This predictable fragmentation is key to its utility as a mass calibrant.

When analyzing samples using GC-MS, the instrument's mass axis needs to be calibrated to ensure accurate mass measurements. Perfluorotributylamine is ideal for this task because it produces a series of well-defined fragment ions across a broad mass range, typically from m/z 69 up to around 502. These fragments serve as reference points, allowing for precise tuning and calibration of the mass spectrometer. Researchers and lab managers often seek to buy high-purity Perfluorotributylamine to guarantee the accuracy of their analytical instruments.

The benefits of using Perfluorotributylamine as a GC-MS calibrant include its high boiling point, which means it can be introduced into the mass spectrometer at relatively high temperatures without significant loss, and its chemical inertness, which prevents unwanted reactions with the instrument's components or the sample matrix. This makes it a robust and reliable calibration standard for a wide array of applications, from environmental monitoring to pharmaceutical research.

For those looking to procure this vital chemical, sourcing from a reputable manufacturer and supplier is crucial. Companies specializing in perfluorinated compounds, like those based in China, offer competitive pricing and high-quality products. When you search for a 'perfluorotributylamine supplier,' prioritize those with a strong track record in producing chemicals for analytical applications. Ensuring you purchase from a trusted manufacturer will guarantee you receive a product that meets stringent purity standards, essential for accurate GC-MS calibration.
