Using 1064 nm Dispersive Raman Systems For Analysis Of Petroleum Products
Raman spectroscopy is a non-invasive, highly sensitive technology that quantitatively probes and analyzes chemical compositions and structures without the need for sample preparation. In the past, this technology was not useful for petroleum and petroleum-based products due to their high levels of high level of photoluminescence that can overwhelm Raman signals in all visible wavelengths. This issue is now resolved by BaySpec’s line of 1064 nm excitation dispersive Raman systems that offer maximum reduction in fluorescence interference.

Palm-Held SWIR Spectrometer For Identification And Classification Of Materials
Today, Recycling issues surrounding environmental sustainability has gained world-wide importance. As developing countries refuse to take in waste, more plastics and other recyclable materials are ending up in landfills, incinerators, or simply littering the environment. The rising costs to haul away recyclable materials increasingly render the practice unprofitable, as well it is aggravating the burden on local department.
Schools And Safety: How UVC LED Technology Can Help Re-Opening Safely
As late summer approaches, the safe reopening of schools is of major concern, as the COVID 19 pandemic continues.
