Ensuring accurate HPLC method comparison and transferability

Testa Analytical highlights how its FlowChrom real-time flow monitoring system makes it possible to directly compare and transfer HPLC methods and results between instruments - even across different labs or locations.

In many organisations, multiple HPLC systems run the same separation protocols across large sites or globally distributed labs. Industries such as pharmaceuticals, food, and agriculture must meet strict laboratory data quality standards, including Good Laboratory Practices (GLP) and international standards like ISO/IEC 17025.

The challenge: ensuring that methods - and the results they produce - are truly comparable across different sites. Simply equipping every lab with the same HPLC or UHPLC system often falls short. Even ‘identical’ instruments running the same protocol can yield subtly different results, sometimes for reasons that aren’t immediately obvious.

The solution lies in real-time monitoring. By fitting HPLC systems with FlowChrom, labs can measure actual flow rather than assuming set flow rates are perfectly reproduced. This non-invasive, automated system uncovers hidden operational differences, allowing labs to pinpoint inconsistencies and correct them.

The result: robust lab-to-lab interoperability and reliable transferability of HPLC methods and results. FlowChrom provides an elegant, cost-effective, and proven way for analytical teams to achieve true consistency across instruments and locations.
