New technologies in the NIR

Just had an article come out in Spectroscopy magazine detailing some of the more interesting developments in NIR spectroscopy in the past few years.  Hyperspectral imaging has taken center stage in NIR, but otherwise many people still think of dispersive spectrometers...

New AtomAnalyzer LIBS software is released!

AtomTrace has launched a new software suite called the AtomAnalyzer that is revolutionary in approach.  Using a simple graphical interface, analysis methods are programmed into the software.  With clear visualization of the operations, users can easily test and...

See us at CLEO in San Jose!

Come by CLEO booth 1429 to see us and talk about Gasera trace gas sensors, SPECTRAL Industries echelle spectrometers, AtomTrace LIBS systems, and TimeGate Raman systems.  Cutting-edge near-IR spectroscopy solutions from Spectral Engines and TSI’s Raman and LIBS...

New LIBS update published in Applied Spectroscopy!

Most of my writing energy for the last few months has gone into writing a Focal Point review article on LIBS for Applied Spectroscopy.  It’s been a lot of fun.  In the article, co-author Amy Bauer and I discuss some of the most interesting LIBS papers of the last 18...

IFPAC 2017

Come see Kevin and Steve at the Spectral Engines booth!  We are available for meetings and to talk about “all things Spectroscopic!” From the meeting website: Process Analytical Technology is one of the most exciting and important advanced technology areas meeting...

Photonics West

Meet Kevin and Steve at Photonics West – the world’s largest multidisciplinary event for photonics!  Every year over 20,000 people come to hear the latest research and find the latest devices and systems driving technology markets including state-of-the art medical...

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...
