This will help Dr Maisch HPLC meet demand for new HPLC columns
Flow meter manufacturer Biotech Fluidics has reported that renowned expert in liquid chromatography Dr Maisch HPLC GmbH has installed a Biotech Liquid Micro Flow Meter in its testing facility to validate the performance of the capiliary columns it manufactures.
Based in the south west of Germany, Dr Maisch the company aims to provide its customers with specially-developed phases to cope with the increasing demand for new HPLC-columns to solve routine and the most demanding separations.
In liquid chromatography the flow rate is an essential parameter of the fluidic system running through a capillary column, as it affects retention time and efficiency.
To ensure high customer satisfaction Dr. Maisch tests every column it manufactures to ensure they are well packed and meet tight performance specifications.
However, measuring the flow rate, especially at extremely low flow rates delivered by capillary columns, can be challenging.
Johannes Maisch, CEO of Dr Maisch HPLC GmbH – said: “to have close control of our capillary testing procedure we installed a Biotech Liquid Micro Flow Meter in our chromatographic test system. With this reliable device we can validate that our test system for produced capillary columns is running at the correct flow rate.
He continued: "Using the Liquid Micro Flow Meter, we can now monitor the flow rate continuously, and with full system control can validate our performance testing of individual capillary columns. We have also found that in-line solvent degassing using a Biotech Degasser is another important part of keeping the system performance at the highest level.”
Dr Maisch HPLC has established a reputation as a leading developer of high-quality standard and specialist capillary columns for HPLC and UHPLC over 45 years.
