What is absorbance?
Absorbance is related to the number of photons a sample absorbs. When an atom or molecule absorbs a single photon, an electron makes a transition to a higher orbital energy. As the number of atoms or molecules increases more photons can be absorbed. The number of...Sunkissed on my COVID Beach Vacation
After months of being cooped up at home, I decided I needed a change of scenery…responsibly. It was the perfect time to take a semi-staycation. I rented an Airbnb, packed up my car, and headed for a home near a secluded beach. I relaxed, swam in the pool, BBQ ’d...Spectral Tests for a Good Night’s Rest with Kimberly
Anyone who knows me knows I’m not a morning person. I recently woke up late in the night with my mind momentarily tricked into thinking it was morning by the light creeping in between my drapes. This happens on many-a-night, but this time I had an “a ha!” moment....What is Signal to Noise Ratio?
The signal to noise ratio, often abbreviated S/N, is exactly what it sounds like; it’s the ratio of the magnitude of the signal to the magnitude of the noise. Experiments need a large S/N to be able to distinguish features in the signal from the noise. If the S/N is...What is Dark Spectrum (concept)?
The dark spectrum of a spectrometer is a spectrum taken with no light hitting the detector. It captures the shape of the baseline offset. It can be used to adjust sample spectra for non-uniformities in the detector pixels. The SpectraWiz software is able to do this...
