Scattering
a propagating wave or moving particle's linear trajectory, interrupted by non-uniformity in the medium they move through.

Saybolt Color Analyzer
-
optek’s Saybolt color analyzer is a dual wavelength light absorption sensor. Operationally, the sensor passes a white light beam through the stream to be monitored, where light absorbance is measured at two distinct wavelengths. The measuring wavelength is set to focus on or near the peak absorbance point of the “yellowness” curve, while the secondary wavelength is chosen to compensate for any influence due to light scattering (window fouling, particulate, immiscible fluids, gas bubbles, etc.). Together, the sensor yields a repeatable and reliable true color number without any sample conditioning.

Field-installation Type Turbidity Meter (Four-Wire Transmission, High-sensitivity)
HU-200TB-H
-
HU-200TB-H connects flow-through type turbidity sensor (SS-120-H) and measures turbidity. It accurately measures turbidity in the range of low to medium concentration (10 degrees) by the 90-degree transmission scattering method with less stray light.Optimal for control and monitoring of wastewater treatment and production processes.

SERS (Surface Enhanced Raman Scattering) Substrate & SERS Reader – Mini Chemistry Analytic Pack
-
The porous carbon SERS substrate provides not only high signal enhancement due to its strong broadband charge-transfer resonance for large chemical enhancement (as opposed to electromagnetic enhancement in traditional metal-based SERS substrates), but also extraordinarily high reproducibility or substrate-to-substrate, spot-to-spot, sample-to-sample, and time-to-time consistency in SERS spectrum (which is not possible with traditional metal-based SERS) due to the absence of "electromagnetic hot spots" by making the entire surface of the substrate "chemically hot", high durability due to no oxidization, and high compatibility to biomolecules due to its fluorescence quenching capability.
