CONSULTING CAPABILITIES (located in the Boston area)
Consulting services in optical spectroscopy can be provided in the following areas:
| 1. | Optical spectroscopic methods and instrumentation |
| Methods and instrumentation for chemical analysis and sensing, including near-infrared, mid-infrared FTIR, UV/visible and fluorescence spectroscopy, and hyperspectral imaging. Experienced in spectroscopic analysis applications in the following areas: medical diagnostics, pharmaceutical analysis, counterfeit drug detection, homeland security, environmental monitoring, bioprocess monitoring, and semiconductor quality control and process diagnostics. | |
| 2. | Design and construction of sampling fixtures and optics |
| Design and develop custom sampling fixtures and optics for optical spectroscopic measurements, including fiber-optic probes and fiber-optic elements. | |
| 3. | Multivariate calibration (chemometric) method development |
|
Develop multivariate calibration (chemometric) methods for qualitative and quantitative analysis in optical spectroscopy. These methods, which are carried out by commercial multiivariate analysis software packages, calculate sample material chemical identity, or the concentration of specific sample chemical components from spectral data obtained from a sample.
