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...
