Do You Need an RFID-Tagged qEV Column for Manual EV Isolation?
Understanding RFID Tags and the Automated Fraction Collector
Some qEV columns include RFID tags, which can lead to a simple question: does the RFID tag matter if you are performing extracellular vesicle isolation manually?
The Short Answer
No. RFID tags are not required for manual qEV isolation.
The RFID tag is used for column detection when working with the Automated Fraction Collector (AFC).
What Does the RFID Tag Do?
The RFID tag does not directly affect the separation performance of the qEV column or the extracellular vesicle isolation process itself.
Its purpose is to allow the Automated Fraction Collector to detect and identify the installed column.
If fractions are being collected manually, the RFID tag has no functional role in the isolation workflow.
Manual vs. Automated qEV Isolation
| Feature | Manual Isolation | With AFC |
|---|---|---|
| Fraction Collection | Collected manually | Automated |
| RFID Tag Required | No | Used for column detection |
| Column Detection | User verified | Detected by AFC |
| Best Fit | Manual workflows | Automated, repeat workflows |
When Is an Automated Fraction Collector Useful?
qEV size exclusion chromatography workflows typically require fractions to be collected at defined volumes.
For occasional or low-throughput experiments, fractions can be collected manually. However, when processing multiple samples or performing repetitive workflows, automated fraction collection can reduce hands-on steps and help standardize the process.
In these workflows, the RFID tag supports communication between the installed column and the fraction collection system.
Replacing an ICO-70 Column?
Before selecting a replacement column, it is helpful to confirm whether your current workflow is manual or uses an Automated Fraction Collector.
RFID functionality is not required for fraction collection.
Confirm that the replacement column configuration is compatible with automated column detection.
