Should You Use a Glass Pre-Filter Syringe Filter?

Proper sample filtration is a key step in chromatography that directly impacts both analytical accuracy and instrument performance. High-quality filtration ensures consistent, reliable results while minimizing wear on sensitive components like pump seals, injector valves, and columns. One of the most popular and cost-effective filtration tools for chromatographers is the syringe filter — known for its simplicity, affordability, and wide range of membrane options.

Syringe filters are available in multiple membrane materials, pore sizes, and diameters, allowing for flexibility across diverse sample types and solvents. Choosing the correct syringe filter can significantly improve sample cleanliness and prolong column life. For detailed guidance on membrane selection, refer to our blog post: How to Choose a Syringe Filter.

What About Extra Dirty Samples?

When working with challenging or particulate-heavy samples — such as those in ethanol or environmental applications — filtration can quickly slow due to membrane clogging. For these situations, Chrom Tech offers syringe filters equipped with a glass fiber prefilter.

The glass prefilter provides an additional layer of filtration that captures larger particulates before they reach the main membrane. This improves flow rate, reduces backpressure, and extends the usable life of each filter. While prefilters are highly effective for “extra dirty” samples, they are not always necessary for routine analytical work — and they do come at a slightly higher cost. For most standard applications, a single filtration layer is sufficient before injection.
