Product Description
When precision matters in your lab, this 0.1% TFA water solution from Merck delivers consistent results. Trifluoroacetic acid (TFA) is a volatile acid widely used in HPLC and mass spectrometry due to its excellent ion-pairing properties. This pre-mixed solution eliminates the need for manual dilution, saving time while ensuring accuracy in your experiments.
Researchers and students working with proteins or peptides will find this solution invaluable. The 0.1% concentration is optimal for reverse-phase chromatography, helping to improve peak resolution without damaging sensitive equipment. Whether you’re analyzing synthetic peptides or purifying recombinant proteins, this TFA water solution maintains sample integrity throughout your workflow.
At eqipped, we understand how critical solvent purity is for reproducible results. That’s why we source this product directly from Merck, a trusted name in laboratory chemicals. The 4-liter pack size is ideal for labs with moderate usage, reducing the frequency of reorders while maintaining freshness.

For educational institutions, this solution serves as an excellent teaching tool for demonstrating ion-pairing chromatography principles. The consistent formulation helps students achieve reliable results in their practical experiments, making it a staple in biochemistry and analytical chemistry labs.
Safety Note: Trifluoroacetic acid is corrosive and volatile. Always handle in a fume hood with appropriate PPE including gloves and eye protection. Store in a cool, well-ventilated area away from incompatible substances.
FAQs
What is the shelf life of this TFA water solution?
When stored properly in its original container at room temperature, this solution maintains its specifications for at least 24 months from the date of manufacture. Always check the label for the exact expiration date.
Can I use this for LC-MS applications?
Yes, this HPLC-grade solution is suitable for LC-MS applications. The low impurity profile minimizes background noise, and the 0.1% concentration provides effective ion pairing without overwhelming the mass spectrometer.
How should I dispose of unused solution?
Follow your institution’s chemical waste disposal protocols. TFA solutions typically require neutralization before disposal. Consult your local environmental health and safety guidelines for specific procedures.
Is this solution compatible with all HPLC columns?
While generally compatible with most reverse-phase columns, we recommend checking your column manufacturer’s guidelines. Some specialty columns may have specific pH or solvent restrictions.
Can I dilute this further for lower concentration needs?
Yes, you can dilute this solution with HPLC-grade water to achieve lower concentrations. However, we recommend preparing fresh dilutions daily as TFA can evaporate over time, altering the concentration.
