Solvias AG products

Transmission Flow Cells: For measurement of concentrations of transparent liquids directly within the pipe, we use MONITOR, ARGUS, MINIPLANT or CALILAB measuring cells, all of which have patented optics. The optical path length can be varied from 1 to 20 mm with a simple adjustment of the distance bolt.  Based on the heatable CALILAB flow cell, we developed SYSTEM-CALILAB. This is the ideal solution for method development and calibration in the laboratory. CALILAB also provides a framework for probe design, enabling applications such as intermittent analysis.

BIOPRO transmission flow cells and ZAFIRO BIOFIT transmission immersion probes are of remarkable quality due to the careful selection of materials by Solvias for all the wetted parts. Their CIP/SIP-compliant design meets the most challenging demands for reliable application in sterile production.

EXPANDO transmission flow cells are ideally used where greater optical path lengths are required to determine small concentration using a spectrometer. Areas of application are gas analysis and trace analysis in liquids.

Reflectance Immersion Probes: For the analysis of heterogeneous systems or solids, we offer a complete range of reflection probes. The TURBIDO, REFLECTOR, REFLECTOR FLUSH and ALBEDO products represent an entire range of probes, mainly distinguished by the number of fibers they use internally.

Solvias transflection probes have literally dozens of applications – in multi-purpose plants, in fermentation, or in organic-chemical process development – and thereby provide the user with a high degree of flexibility. For reaction monitoring in transmission mode, the optical path length must be easily and quickly adjustable to rapidly respond to changing concentration conditions. In addition, these probes must be resistant to chemicals, corrosion, and abrasion, and also be suitable for use in high pressure and high temperature conditions. The FLEX transflection probe has been specially developed to satisfy all these requirements.

ATR technology (Attenuated Total Reflectance) allows us to take advantage of the total reflection of the light transmitted from an optically dense medium to a less dense medium. The light at the boundary layer (sapphire/liquid) penetrates approximately a quarter of the wavelength into the less optically dense medium, where it can be absorbed. With our ATTENUTO probe, the optical path length falls within the sub-micrometer range, allowing for the analysis of highly concentrated solutions while eliminating time-consuming dilution steps.
