Presentation

Visible-UV spectroscopy is an analytical method focusing on the electronic transitions of the products of interest. This type of spectroscopy offers very high sensitivity (up to 10 to 100 times that of NIR or Raman spectroscopy). This is why the pharmacopeia recommends it for quantitative and qualitative studies in the laboratory.

A versatile tool which can adapt to your needs
Asuryan lets you measure your product in less than 50ms. It offers excellent stability thanks to simultaneous measurement of the source’s spectrum. Several spectrometers can be integrated into Asuryan to perform measurements on several key phases of the process (dilution, filling, etc.), thus giving an immediate snapshot of your whole process. This flexibility proves essential in processes manufacturing or consuming high added-value or very varied products…

Constantly optimized measurement
Asuryan can adapt to a large number of sensors (immersion with different optical trajectories, flow cell, SFX multi-angle sensors, ATR signal attenuation sensor) to allow flexibility when measuring diverse products of interest in diverse media. Modulation of the integration time facilitates its integration in multiple media. To guarantee that the measurements are perfectly reproducible, Asuryan can check the stability of the light source by using an additional internal spectrometer.

Unique compatibility with the patented SAM-Spec and SAM-Flex technology
Asuryan is the only system capable of using SAM-Flex multi-angle measuring sensors or SAM-Spec multipoint sensors. These technologies extract more information in complex media (emulsions, suspensions, powders, etc.) by measuring the average globule size and globule density. The different spectra help to improve separation of the information on the milieu from the data on the products in suspension.

Various possible configurations
Three configurations are possible, depending on your requirements:

Simple high-stability configuration: one channel devoted to measurement (SMA) associated with an internal channel for measurement of the light source (2 integrated spectrometers).
Standard three-channel configuration: three measurement channels in parallel (3 integrated spectrometers).
High-stability three-channel configuration: three measurement channels in parallel with internal measurement of the light source (4 integrated spectrometers).

Technology incorporating measurement and analysis software
The integrated Asuryan Ready software lets you modulate measurement acquisition, particularly in terms of the integration time, number of scans, etc. It is controlled via the OPC-UA communication protocol, or directly in stand-alone mode. This software also enables you to integrate several chemometric models obtained using toolboxes such as PLS_Toolbox (ACP and PLS models). Once these models have been integrated, they let you monitor the process’s critical parameters on your display.

 

Example of an industrial application

Evaluation of the protein concentration of a liquid!

Thanks to the characteristic UV wavelengths of interest and its flexible measuring configurations, Asuryan is the ideal tool for analyzing protein blends, among other advantages enabling you to:

• Assess the protein content on large series
• Detect protein adsorption on an adjuvant
• Check protein purity in a milieu
• Check the concentration of the products of interest in a reactor at the same time as filling the vials

 

 

Advantages

• Adaptable to different sensors for use on a wide range of products or concentrations of the product of interest
• Measurement on several phases of the process
• Quick measurement, thus reducing analysis time and allowing continuous monitoring
• System with an internal reference for optimum repeatability
• Integrated software facilitating analysis and data processing by means of models focusing on the variable of interest
