Enabling Direct Extraction of Non-Potable Water with the Inline Filters

Updated: Nov 10


Non-potable water samples may require separate filtering steps prior to performing extraction. It can be challenging, disruptive and time consuming to de-clog these samples. Wouldn't it be more efficient if you can do filtering and extraction in just one step? No more deviating from normal procedure.


With these considerations in mind, PromoChrom is presenting you our Inline Filters - a simple solution that allows you to directly extract dirty samples. Some of the critical key benefits of using inline filters include:

  • All samples pass through the inline filters

  • Protect your automated SPE system

  • Reduce cartridge clogging

  • Recover any trapped analytes during bottle rinse

  • Free of PFAS

Maximize the Benefits with MOD-00P

The inline filters work best with MOD-00P, a new configuration introduced to our SPE-03 system in 2020 that splits each sample line into two – one for drawing samples and another for bottle rinsing. This enables the sample draw line to have a larger internal diameter leading up to the inline filter connection. The filter does not impede the bottle rinse regardless of how clogged it gets. The configuration has allowed the SPE-03 to perform more non-potable water applications such as EPA Method 1633. The MOD-00P sample lines also allow for upright sample bottle mounting to minimize the amount of sediments being drawn through.



More recently, we have applied the same dual-line design to MOD-004 with systems that have the MOD-00P configuration. This allows samples with more particulates to be extracted following EPA Methods 537.1, 533 and modified methods, without affecting the bottle rinse.
