FAQ: How can I collect, and store data generated by my Flowmeter?

A: Our liquid flowmeters are designed to interface to any PC via an integral USB interface. For real-time data collection, visualization and storage, two options are available: the Flowmeter PC-App and the Chromatography Data System (CDS) Driver. Our easy-to-use PC-App is widely used for validating the consistency of performance of pumps serving dispensing, flow chemistry and liquid chromatography applications. For labs looking to fully integrate flow data with liquid chromatography data, our powerful CDS Driver software provides a direct interface to different HPLC software packages from the leading HPLC system suppliers. This software package enables storage of flow rate data along with each and every chromatogram, thus opening the gate to a total quality assessment environment.

Speciality liquid chromatography detectors.

Do you need a new high-performance liquid chromatography detector but do not have the time or resources to develop it inhouse? Developing a new liquid chromatography detector requires a partner who understands the specific chromatographic needs of you target application and can transform these needs into a high-quality tailored solution. Drawing upon decades of chromatographic expertise and knowledge, TESTA Analytical has repeatedly proven ourselves as a highly effective speciality HPLC, UHPLC and GPC/SEC detector development and supply partner to a growing number of instrumentation companies worldwide.

Ensuring reproducible HPLC separations in different solvents.

HPLC separation protocols employ many different solvents to accommodate the varying properties of different analytes. Ensuring consistent elution profiles is a key requirement to ensure reproducible results. Continuous monitoring of the delivered HPLC eluent flow rate is therefore essential when permanent validation of results is desired or necessary as it is in regulated industries. A new technical study demonstrates the utility of our non-invasive liquid flowmeter for validating the performance of HPLC systems across a wide range of different solvents.

TESTA flowmeter software driver approved by Agilent.

After extensive testing, Agilent Technologies has confirmed its full approval for our rc.NET based software driver which enables seamless integration of TESTA flowmeter data with their powerful OpenLab Chromatography Data System (CDS) software. The software driver supports all non-invasive liquid flowmeters from TESTA Analytical enabling real-time storage of flow rate data along with chromatograms thus opening the door to continuous monitoring of Agilent HPLC / UHPLC system pump performance. This innovation represents a breakthrough in total quality assessment of chromatography data and is expected to become a standard requirement especially in regulated industries.

Looking to replace an ageing SLD7000 MALS unit?

Over the last 15 years - the PSS SLD 7000 Multi Angle Light Scattering (MALS) established itself as a tried and trusted device for direct determination of the absolute molecular weight distribution of polymers. Available as a direct, modern replacement for your SLD 7000 - our Bi-MwA MALS detector offers the highest performance to price ratio of any light scattering system available for molecular weight determination. If you are looking to determine absolute molecular weights of synthetic polymers, proteins or other macromolecules quickly and accurately, then look no further. The Bi-MwA is a powerful tool that can dramatically increase the capability of any GPC/SEC system enabling the precise and accurate determination of the molecular weights of polymers and nanomaterials in solution.
