Read about some of the latest discoveries in spectroscopy, new innovative optical sensing instruments, and our participation at upcoming events.
LIBS in the French Alps
I was skeptical. Could a LIBS conference in the relatively remote town of Chamonix really be a good idea? I should not have been skeptical. Thanks to Prof. Jin Yu and his team, the biannual International Conference on LIBS has been a smashing success, with nearly...
Novel, compact NIR and MIR spectrometers!
Back from vacation … hopefully you’ve been having a great summer. I wanted to write today about the newest addition to our product lineup here at Flash Analysis. The Spectral Engines’ NIR and MIR devices are tiny Fabry-Perot spectrometers that do an outsized job of...
Polypropylene Mechanical Properties with Raman
Machine learning is able to reliably extract an incredible amount of data from both Raman and LIBS spectra. One of the most interesting recent examples was published recently in Applied Spectroscopy , in which Julio Banquet-Terán and co-authors showed that a...
Analysis of Spectra
Today I was going back through my files and noted an “oldie but goodie” – a paper on background fitting for LIBS and Raman spectra by Igor Gornushkin and colleagues from 2003. Specifically: I. B. Gornushkin, et al. “Automatic Correction of Continuum Background in...
Analysis of Spectra – Raman and LIBS
Today I was going back through my files and noted an “oldie but goodie” – a paper on background fitting for LIBS and Raman spectra by Igor Gornushkin and colleagues from 2003. Specifically: I. B. Gornushkin, et al. “Automatic Correction of Continuum Background in...
Selecting a LIBS Laser Wavelength
I am often asked how one should choose the wavelength of the laser for LIBS analysis. This is particularly important for applications involving nanosecond lasers, where the laser-material interaction is pronounced. For femtosecond lasers, the laser pulse is so fast...
Convenient SERS subtrate for Raman
Surface-Enhanced Raman Scattering (SERS) is of substantial interest as a means of amplifying the typically relatively weak Raman signal. One issue with SERS is finding substrates with high enhancement factors that are cost-effective to produce. Recent years have seen...
LIBS for Sulfur and Phosphorous in Steel
Pretty amazing reading today - successful detection of sulfur and phosphorous in the visible region of the spectrum - in steel, at useful levels (e.g. below 0.005% for S and below 0.035% for P). See, with LIBS both of these elements are typically detected in the deep...
Raman for Early Detection of Citrus Disease
I was reading a great article today in Applied Spectroscopy about a novel application of Raman spectroscopy. Apparently there is a disease called Huanglongbing (HLB) or ‘Citrus Greening Disease,’ which threatens a large portion of the global citrus crop. The way...
A New Day – Research Blog Begins
Hi Friends of Flash! Today we’re starting a new research blog meant to keep up with some of the latest developments in LIBS, Raman, Near Infrared (NIR), and Mid Infrared (MIR) spectroscopy, including not only hardware but also software as well.. We’re intending to...
