ATR Immersion Probes for Chemical and Biological Applications

The chemicals, bio-chemicals and pharmaceuticals industries in Europe manufacture a variety of products and provide services that touch the lives of all individuals. Hosting ⅓ of the world’s overall production, the EU is a leading chemical production area.

Despite this fact, global competition is increasing and companies are now searching for innovative technologies that will reduce the time to market new products and boost the effectiveness of their innovation.

Fiber Optic Immersion Probes

In the chemicals sector, analytical measurements such as spectroscopy are used to meet metrology challenges in order to offer physical, chemical and biological information in combination with Multivariant Statistical Process Control (MSPC) or better termed Multivariate Statistical Process Monitoring (MSPM) and advanced, mode based, process control (APC) and optimization.

In biotechnology, biological processes are often poorly understood as they are highly complex. In general, the knowledge of the elementary fermentation phenomena is incomplete and therefore fermentation processes cannot be optimized on the basis of theoretical assumptions.

Experiments have to be performed which are both expensive and time-consuming. In order to offer a better insight into process scale-up, the biotechnological experiments have to be carefully designed, and usually extensively, with respect to the process and product scale-up and ultimate manufacture. Real time mid infrared (MIR) data is provided by miniaturized in-situ fiber optic immersion probes that can considerably increase the accuracy of chemical determination and reduce the costs of carrying out at line or even remote measurement.

Art photonics offers an extensive range of ATR immersion probes for clean-tech, chemicals, environmental, and food and drink applications.

It is now possible to realize reliable in-situ spectral measurements of basic molecular vibrations in the ‘fingerprint region® (550 to 3300 cm-1) for liquid chemical processes. Overall, three spectral ranges are available:

Range Wavenumber Wavelength
Mid Infrared 550 – 3300 cm-1 3 – 18 µm
Near Infrared 1650 – 6650 cm-1 1.5 – 6.0 µm
UV/VIS/NIR 4700 – 55550 cm-1 180 – 2100 nm

 

Fiber Optic Probes

The FTIR analyzer can be upgraded with immersion probes for pilot plant, in-process and laboratory applications.

Fiber Optic Spectrometers

High performance, fiber optic coupled instrumentation can be used to determine the chemical composition or physical property of a process sample or stream.

Fiber Optic Probe Fittings

Automatic sensor lock-gate is employed for intense applications with ceramic sealing to the process.
