Turkish market delights in LC flowmeter.

Our knowledgeable local agent in Turkey - DOA Laboratory Technologies reports on an enthusiastic response to demonstrations of the LC Flowmeter and HPLC Pump Qualification Pack from chromatographers working in regulated industries such as Pharmaceuticals. The HPLC Pump Qualification Pack which includes a TESTA Analytical LC flowmeter, tablet-computer with pre-installed data validation software is designed to automatically perform all necessary flow data calculations plus operational and performance qualification checks on your HPLC system.

Audit ready HPLC pump performance validation.

Version 1.4 of our popular HPLC Pump Qualification Pack includes a series of updates that make the tool more flexible and audit ready. Improvements include a new Pump Validation Checklist to guide users through the validation process step by step, ensuring a structured workflow thereby reducing the chance of errors. Users can now adjust accuracy acceptance limits from 0.5% to 5% (the European Directorate for the Quality of Medicines and HealthCare (EDQM) standard). This flexibility allows users to align their validation protocols with various regulatory standards and different pump specifications. The HPLC pump qualification passing criteria now consider both relative standard deviation and nominal deviation, in accordance with EDQM guidelines.
