Wet Foam Elution™

The Technology Behind AirPrep™ and FluidPrep™

Wet Foam Elution™ (WFE™) is InnovaPrep's patented sample recovery technology designed to transform collected particles into concentrated, analysis-ready liquid samples.

Whether sampling air, water, wastewater, food products, environmental samples, or bioprocess fluids, collection is only the first step. The value of a sample ultimately depends on how efficiently collected material can be recovered and delivered to downstream analysis.

Originally developed to address demanding aerosol collection and recovery challenges, Wet Foam Elution now serves as a foundational technology across InnovaPrep's AirPrep™ and FluidPrep™ platforms, supporting applications in environmental monitoring, biosurveillance, public health, food safety, life science research, bioprocessing, and defense.

By combining rapid recovery and concentration into a single workflow step, WFE enables users to recover more value from every sample collected.

Wet Foam Elution™ uses a controlled expanding foam that gently contacts the entire collection surface, efficiently releasing retained material while requiring only a small recovery volume.

A Different Approach to Sample Recovery

Unlike traditional liquid rinsing or soaking methods that rely on large liquid volumes and may leave material trapped within collection media, Wet Foam Elution™ uses controlled foam expansion to gently mobilize and recover collected particles.

 

The result is a concentrated, analysis-ready sample suitable for downstream applications including PCR, sequencing, culture, flow cytometry, microscopy, immunoassays, and other analytical methods.

Supporting Air and Liquid Workflows

Wet Foam Elution™ serves as a foundational technology across the InnovaPrep platform.

EasyElute™ Workflows

Support efficient recovery from large-volume concentration workflows.

Why Recovery Matters

Successful sample collection is only the first step. 

 

The challenge is recovering them in a form that preserves analytical value while minimizing dilution and workflow complexity.

 

Wet Foam Elution™ helps support:

     ✓ Small-volume sample recovery

     ✓ Concentrated, analysis-ready samples

     ✓ Compatibility with diverse biological and particulate targets

     ✓ Integration with modern analytical methods

     ✓ Workflows spanning air and liquid sample preparation

From Collection to Insight

Characterize → Collect → Recover → Analyze (or) Characterize → Condition → Clarify → Concentrate, depending on branding strategy

Wet Foam Elution™ helps transform collected particles into usable analytical samples, enabling researchers, laboratories, public health organizations, technology developers, and defense programs to recover more meaningful information from every sample.
