Join us at SciX 2021, Booth 312 from Sept. 27-29 in Providence, Rhode Island, USA. This is our first in-person event in more than a year and will will focus the spotlight on our Raman offering.
In addition to the live meeting experience, SciX 2021 will provide post-meeting access to programs and presentations via an on-demand library. For those that do plan to attend, here’s what to expect from us.
Less expensive than traditional scientific-grade Raman instruments yet sacrificing very little in performance, Ocean HDX Raman is a compact, high-performance spectrometer for 785 nm Raman excitation applications. Ocean HDX Raman unlocks Raman signature data from 150 cm-1 to 3400 cm-1 and is great for applications including identification of polymers and characterization of pharmaceutical ingredients.
Using our popular Flame spectrometer – distinguished by its thermal stability, excellent unit-to-unit consistency and interchangeable slits – we configure a modular setup for absorbance. Flame spectrometers are available in UV-Vis (200-850 nm), Vis-NIR (350-1000 nm) and extended-range (200-1025 nm) versions, with custom configurations also possible.
Title: Getting LIBS results outside the laboratory: lessons from the field

Schedule: Monday, Sept. 27, 2021, 8:30-8:50 a.m. (EDT)
Location: Meeting Room 550 (Fifth Floor)
Title: Enhancing Spectral Repeatability and Limits of Detection Using Liquid Phase Nanoparticles for Quantitative Raman
Author: Derek Guenther, Senior Applications Scientist
Schedule: Monday, Sept. 27, 2021, 2:10-2:30 p.m. (EDT)
Location: Meeting Room 558 (Fifth Floor)
Abstract: As the pandemic has fueled the need for new, rapid detection methods, much of the focus has been on optical techniques for their speed and portability. One detection method that has seen much growth and commercial adoption over the last decade is SERS, or Surface-Enhanced Raman Spectroscopy. While SERS consumable substrates are offered in a variety of flavors and form factors from many suppliers, one inherent limitation to all is their repeatability within and between production batches. A separate approach is presented here that leaves the signal-enhancing nanoparticles in aqueous suspension and allows the analyte interaction and Raman enhancement to occur in the liquid phase.

Abstract: Surface-enhanced Raman spectroscopy (SERS) has been a topic of interest in the analytical chemistry and spectroscopy communities for many years. Although commercially produced substrates are available for the performance of various types of analyses, expansion of the use of the technique has been hampered by the lack of reproducibility. It is generally recognized that this issue is rooted in challenges surrounding nanoparticle deposition on substrate material.
An alternative approach is to leave the signal-enhancing nanoparticles in aqueous suspension and allow the analyte interaction and Raman enhancement to occur in the liquid phase. We observe greater repeatability in both native gold and silver nanoparticle background signals and the subsequent analyte signal return with the liquid than with the substrate approach. An additional benefit to the use of the suspension is that more laser power can be brought to bear on the measurements without fear of burning substrate materials. Using this approach, useful Raman spectra of a variety of organic compounds have been acquired to the part-per-billion level.
This presentation documents the analysis of hardness in mineral water as a surrogate for other inorganic constituents and contaminants in water. Mineral water samples instilled into 2 ml vials of gold nanoparticles in aqueous suspension have been interrogated with a 785 nm laser and signals collected with an Ocean Insight QE Pro Raman system. Curves of growth, limits of detection, and other measurement statistics will also be presented.
"I joined Ocean Insight believing that there would be no better place to innovate in photonics than at such an iconic company. That has been 100% true."
"There’s a critical bridge between creativity and science. And that connection really feeds into the idea of discovering what can be done that was not done before."
"So many researchers, scientists and engineers are using our products to make measurements in places and ways never imagined. They’re the ones who make the world a better place through optical sensing."
Making Raman more accessible with the 785 nm Raman excitation spectrometer, ideal for a range of applications.
In this video, we demonstrate how our proprietary surface-enhanced Raman spectroscopy substrates enhance Raman signal to detect antibody samples from SARS-CoV-1 and -2 proteins.
