Dual-Channel Process Monitoring: Combining NIR and Raman Spectroscopy in a Single Probe

By Stanislav Perevoschikov

During active pharmaceutical ingredient (API) crystallization and drying, comprehensive process understanding demands simultaneous insight into chemical composition and solid-state structure. Operators routinely track two distinct parameters in real time: residual solvent or moisture content, and crystal polymorphism. Historically, monitoring both attributes in situ presented a practical instrumentation bottleneck. Near-infrared (NIR) spectroscopy excels at quantifying water […]

Simultaneous Determination of Cu²⁺, Co²⁺ and Ni²⁺ by Fiber-Optic Spectroscopy in the Visible and Near-Infrared Range

By Stanislav Perevoschikov

The simultaneous quantitative determination of dissolved Cu²⁺, Co²⁺ and Ni²⁺ ions is important in many fields. These include metallurgy, geology, industrial wastewater analysis and the monitoring of biotechnological processes. In many cases, their concentrations need to be measured directly at the sampling site or in-line during an operating process. The Challenge of Metal Ion Monitoring […]

Fiber-assisted illumination of the skull

The multi-spectral transillumination of the nasal sinuses with μLEDs is the application example from the medical technology, which was conceived in the extensive product pallete of art photonics GmbH.

Sinusitis, also known as a sinus infection or rhinosinusitis, is an inflammation of the air cavities within the passages of the nose. Sinusitis can be acute, orvchronic, which usually lasts for 3 to 8 weeks and can continue for months or even years; recurrent, which is several acute attacks within a year. The optical diagnosis of inflammatory diseases of the nasal sinuses had in the past, in spite of its long history, a number of serious disadvantages that oppose its use in the routine of clinics and practices.

Together with a clinical partner from Charité Universitätsmedizin Berlin, art photonics developed new, innovative concepts for light diagnostics for the ENT. In the re-discovery of diaphanoscopy, miniaturized and improved applicators with powerful LEDs are in the forefront of the use in minimally invasive medicine. The focus of the development of these innovative procedures for the screening of the nasal sinuses is the geometrical and ergonomic design of the applicator, the digitalisation of images and the establishment of the modern image processing methods for the evaluation of the scattered light images. An old, forgotten method of transillumination of the human skull gains therefore a new value in the light diagnosis of the inflammation of the nasal sinuses.

The aim of the project is the development of an equipment for minimally invasive diagnosis of inflammatory diseases of the paranasal sinuses by illumination with visible and near infrared light as a condition of the formation and evaluation of light scattering patterns to low‐cost, non‐invasive, free of ionizing radiation screening for diagnosis and follow‐up.

Advantages:

Noninvasive diagnosis of sinusitis without X‐ray, CT and biopsy to reduce the radiation exposure
Selection of optimal wavelengths for the beam source to distinguish between
different forms of inflammation
Anatomical ‐ based shape of applicator for comfortable transillumination
Development of a diagnostic wizards to simplify and increase the diagnostic accuracy
Cost reduction through the introduction and adaptation of optical technologies

Current status

A universal LED applicator was developed:
