Perfluorokerosene (Super-high boiling) [for Mass spectrometry] from TCI (P1034) is a mixture of hydrocarbons in which every hydrogen atom has been replaced by fluorine. Analysts commonly call it PFK. In the laboratory it is not used as a reactant. Its role is to serve as a mass calibration standard for mass spectrometers. PFK is used mainly with electron ionization (EI), including on high-resolution instruments. The "super-high boiling" grade is designed to give fragment ions at a higher mass range than standard PFK, which extends the calibrated range of the instrument.

Analysts choose PFK because, when ionized, it gives a large number of fragment ions spread across a wide mass range. These ions contain only carbon and fluorine, so their exact masses are well known. Fluorine has a negative mass defect, which makes PFK ions easy to tell apart from the ions of common hydrogen-rich organic compounds. This makes PFK well suited as an internal reference for accurate mass measurement. Perfluorinated materials are also very chemically stable and do not react readily in the ion source, so the reference signals stay reliable from run to run.

In Indonesia, this product is used by instrument laboratories at universities, research institutions and analytical testing facilities that run mass spectrometers with electron ionization. Typical users are teams that need to tune and calibrate the mass axis, check instrument performance, or measure accurate masses for structure elucidation. It is particularly relevant for laboratories that work at higher mass ranges, where standard PFK gives too few reference ions. It supports consistent, traceable results in both research and routine analytical work.

Mass axis calibration: PFK gives many fragment ions with well-known exact masses, which provide dense reference points for calibrating the mass scale of EI mass spectrometers.
High-resolution accurate mass measurement: Fluorine's negative mass defect separates PFK reference ions from hydrogen-rich analyte ions, so it works well as an internal lock-mass reference.
Extended high-mass calibration: The super-high boiling grade gives fragment ions at higher masses than standard PFK, which helps when the calibrated range must cover heavier analytes.
Instrument tuning and performance checks: Its stable and reproducible fragmentation pattern lets analysts confirm resolution, sensitivity and mass accuracy as part of routine instrument maintenance.
Structure elucidation support: Accurate mass data calibrated against PFK helps analysts assign elemental compositions to unknown ions in research and analytical testing laboratories.
