Product Overview
PerfluoroKerosene (PFK) is a specialized high-boiling fluorocarbon blend designed for mass spectrometry applications, offering unmatched precision in instrument calibration. This 50% high-boiling PFK solution in low-boiling PFK provides a stable, chemically inert reference standard that ensures accurate mass-to-charge ratio measurements across a wide range of analytical workflows. The unique fluorinated structure of PFK delivers exceptional thermal stability, minimizing signal drift and enhancing reproducibility in high-resolution mass spectrometry. Its low volatility and resistance to oxidation make it ideal for long-term use in both routine and high-sensitivity analyses. The carefully balanced composition of high and low-boiling fractions optimizes ionization efficiency while maintaining consistent fragmentation patterns. This mass spectrometry-grade PFK undergoes rigorous purification to eliminate trace contaminants, guaranteeing reliable performance in critical applications where analytical precision is paramount. The 1mL pack size offers convenient handling for frequent calibration needs while maintaining cost efficiency for research laboratories.
FAQs
1.
What is the boiling point range of this PFK blend?
The high-boiling PFK component typically ranges between 215-230°C, while the low-boiling fraction falls around 100-130°C, creating an optimal balance for mass spectrometry applications. 2.
Can this PFK be used with both ESI and MALDI ionization sources?
Yes, this PFK formulation is compatible with various ionization techniques including ESI, MALDI, and APCI due to its stable fragmentation pattern and consistent ionization efficiency. 3.
What is the typical shelf life of this PFK solution?
When stored properly in its original sealed container at room temperature, this PFK blend maintains its performance characteristics for at least 24 months from the date of manufacture. 4.
How does this compare to other common mass spectrometry calibrants?
Unlike polyethylene glycol or protein standards, PFK offers a broader mass range coverage with simpler spectra, making it particularly valuable for high-resolution instruments requiring frequent calibration. 5.
What precautions should be taken when handling this PFK solution?
While chemically inert, PFK should be handled in a fume hood as the vapor may displace oxygen in confined spaces. Always use appropriate glassware as PFK can dissolve some plastics.
