The OMA-300-InGaAs uses an Indium Gallium Arsenide detector and can be configured to scan across in one of three wavelength ranges – 1350-1650nm, 1550-1850nm, & 1750-2150nm.
The OMA-300-InGaAs Process Analyzer produces results in real time by measuring the light absorbance of a liquid or gas sample by utilizing the Beer-Lambert law to correlate the light data to the chemical concentration of an analyte. The OMA-300-InGaAs uses an Indium Gallium Arsenide detector and can be configured to scan across in one of three wavelength ranges – 1350-1650nm, 1550-1850nm, & 1750-2150nm.
These wavelengths are applicable for measurements such as moisture in solvents, moisture in propylene, ethylene concentration, pharmaceutical HPLC carrier solvents verification, acrolein purity for moisture and acetaldehyde and more .
To analyze the chemical composition of the sample, the OMA performs infrared spectroscopy using an InGaAs (indium gallium arsenide) sensor. The system measures absorbance at 1350-1650nm, 1550-1850nm, & 1750-2150nm. and quantifies the amount of light absorbed by the sample; the OMA plots this raw data to visualize a high-resolution absorbance spectrum.
The OMA uses a long-life tungsten light source to transmit light through the sample fluid in the flow cell. The light is carried by fiber optic cables from the analyzer to the flow cell, where the chemical mixture of the sample has unique interactions with the light based on its current composition.
Wetted materials for the sample conditioning system include: SS316/316L, viton, PTFE, BK7 Glass.
Note: All performance specifications are subject to the assumption that the sample conditioning system and unit installation are approved by Applied Analytics. For any other arrangement, please inquire directly with Sales.
