Determing Percent Ethanol and Menthol in a Spray Solution The Luminar 3060 Multiplexer NIR analyzer can be used for successful quantitative analysis for control purposes in the processing of menthol solution. This can be accomplished by installing the analyzer with single fiber optical cables and a transflectance probe. |

Online Analysis of Recovered Solvents The Luminar 3060 Multiplexer AOTF-NIR analyzer is an excellent tool for making continuous, real-time on-line measurements of solvent recovery streams. A fiber-optic multiplexer can measure up to 16 streams efficiently using the same analyzer, which creates a tremendous cost benefit. The solvent recovery process can now be controlled in a closed loop operation based upon the NIR results. Flow cells as one of fiber-optic solutions are installed in by-pass and the process operators will take samples from the sample point next to the transflectance probes. |

Measurement of a Powder Drying in a 130°F Process Oven Brimrose AOTF-NIR Free Space spectrometer is ideal for applications that require monitoring percent moisture in a powder blend. The spectrometer being insensitive to ambient light and vibrations makes it the ideal choice for any industrial process application. The Brimrose Free Space collects spectra on powder falling from conveyor belt. Data is processed and percent moisture determined. |

Monitoring Concentration of Components Whether the compound or solution consists of only one or two components or many, when the concentration of any one component is out of specification, the result is a process line that must be stopped and the possibility of having to re-process. The Luminar 3060 Multiplexer AOTF-NIR analyzer can be configured and adapted to any process for real-time inline monitoring, thereby possibly avoiding the necessity to re-process. Specific applications include:

Resin/Hardener Ratio Depending upon the particular application, both the Brimrose Free Space and the Multiplexer units are ideal choices for monitoring the ratio between two compounds. The two compounds are blended together by various process methods and monitored for the precise ratio. If either compound is outside acceptable parameters, an alarm is sent to correct the blending control and the process streams are adjusted accordingly. The followings are the spectra results:
