Harmful Algal Bloom Species and Identification Strategies Application of simultaneous absorbance and fluorescence excitation-emission matrix (EEM) analysis to identify and classify freshwater planktonic algal species. Main foci were two major potentially toxic cyanobacterial species associated with algal bloom events in the Great Lakes. Download the PDF Identification of Inorganic Filler Materials in Polymers Combined investigations in the far and mid infrared region in a single scan can offer great value for the analysis of polymeric materials. With the use of optical components optimized for combined FIR-MIR spectroscopy, consisting of a wide range mid to far IR beamsplitter and detector, the investigation of both spectral regions in single step is possible. Download the PDF Infrared Transmission Measurements of Diffuse Samples An infrared transmission spectrum of lens tissue was collected and compared with a sample spectrum collected in the FT-IR sample compartment. Benefits of using an integrating sphere are discussed. Download the PDF Raman Analysis of Embedded Contaminants Raman confocal spectroscopy is increasingly being applied for the analysis of embedded contaminants within materials. A non-contact, non-destructive analysis method, Raman spectroscopy requires very little sample preparation, has greater spatial resolution compared to FT-IR microscopy and the confocal analysis method allows visualization of materials within a clear sample matrix. This paper will investigate the analysis of an embedded contaminant within a polymer matrix on a glass substrate. Download the PDF Diamond Anti-Reflection Coating Spectral Systems has developed its Diamond XP-BBAR™ coating with spectral performance. The SNR is about 30% better through most of the analysis region of a typical FT-IR instrument. www.spectral-systems.com Download the PDF Bringing New Life to Old Arteries with Oxygen In this application note, we focus on the peripheral artery disease (PAD) and its treatment, utilizing NeoFox optical oxygen sensor system to demonstrate how oxygenation increases stem cell survival and leads to improved therapeutic outcomes for PAD patients. Download the PDF Real-time Pharmaceutical Analysis with 1064 nm Dispersive Raman Spectroscopy Pharmaceutical samples often produce strong fluorescence under laser excitation, which prohibits Raman polymorph and ingredient analysis. BaySpec�s dispersive 1064 nm Raman systems offer ultimate solution for fluorescent-free, best signal-to-noise Raman analysis. Download the PDF Measurement of Gold Nanoparticle Solutions on LAMBDA 265 Personal Array UV-Vis Spectrophotometer Learn how to measure properties of gold nanoparticles that have unique optical, electronic, and thermal properties and used in a wide range of applications including diagnostics assays, microscopy, and electronics. Download the PDF Ultra-Compact Near-Infrared Spectrometer for PAT The article provides a typical example of combining an in-line miniature near-infrared spectrometer with design of experiments (DoE) and multivariate analysis (MVA) tools to optimize a multi-component blending process.
