## FAQ

### What is a syringe filter used for in HPLC?

It removes particles from a prepared sample before it goes into the autosampler vial. That protects tubing, frits and the column inlet from blockage and helps keep runs repeatable.

### What does a 0.22 µm syringe filter mean?

The membrane pores are rated at 0.22 µm, which is 0.00022 mm or 220 nanometres. Particles larger than that rating are held back; dissolved molecules pass through.

### What is the difference between a 4mm and a 13mm syringe filter?

The diameter. A 13 mm filter suits larger sample volumes. A 4 mm filter has a smaller housing, so it suits small-volume work where less liquid should stay trapped.

### Does a syringe filter remove dissolved impurities from a peptide sample?

No. Dissolved molecules pass through the membrane. A 2014 review on peptide-related impurities describes impurities from solid-phase synthesis that the HPLC method, not the filter, must separate.

### Is a PES syringe filter a good choice for HPLC sample prep?

PES is one membrane option. Whether it suits your work depends on your solvent and sample diluent, so check the filter maker's chemical compatibility chart before filtering.

### Can I reuse a syringe filter between samples?

No. Filters are single-use. A reused filter carries over leftovers from the first sample and may already be partly clogged, which raises resistance at the plunger.

### Why does my plunger feel hard to push through the filter?

The membrane is likely loaded with particles, or the filter is too small for the volume. Do not force it. Swap the filter or spin the sample down first.
