Optical Emission Spectroscopy for Plasma Systems

Posted on: February 27th, 2023

Optical emission spectroscopy is a powerful tool for monitoring plasmas in situ, enabling process optimization and control. It is used to measure the energy difference between excited and ground states of neutral atoms and molecules and can help to precisely control the parameters of the plasma to maintain stable, reliable, and reproducible processes. Avantes multichannel…

Raman vs Infrared Spectroscopy Measurement of Octasulfur

Posted on: January 27th, 2023

Infrared and Raman are both categorized as vibrational spectroscopies, which broadly speaking, measure the same basic material properties. Namely, they provide a molecular fingerprint by determining the vibrational energy levels of a given material. The term fingerprint, in this case, is used to highlight the fact that for two materials to have the same vibrational…

Measuring the Chlorophyll in Poinsettias with Fluorescence Spectroscopy

Posted on: December 18th, 2022

Background/Applications: Chlorophyll is the essential pigment that allows plants to absorb energy from light. It absorbs light most strongly in the blue and red portions of the visible spectrum and weakest in the green portions of the spectrum, which gives it its recognizable green color. Detection of chlorophyll dates back to the early 19th century…

Absorbance Testing on Weed Killer Using Spectroscopy Instruments

Posted on: November 3rd, 2022

Roundup Experiment In this experiment, we tested low concentrations of glyphosate with a special variable path length dip probe with a narrow tip to measure the chemical’s absorbance. We tested the dip probe with a path length of 10mm and 5mm to also measure the limit of detection for the lower concentrations. As path length…

Spectroscopy Experiment: Dry Ice Effect on Color Absorbance of pH Indicators

Posted on: October 27th, 2022

In this experiment, we tested the color change of three pH indications from a basic initial state to an acidic final state. The three indicators used were universal indicators, bromocresol green, and phenol red. Dry ice was used to increase the acidity of these solutions. Dry ice is the solid form of carbon dioxide, and…

Fluorescence of Anthocyanins in Blueberries

Posted on: September 13th, 2022

Background/Applications: Anthocyanins are water-soluble pigments that are responsible for the red, purple, and blue coloring in fruits and vegetables. The colored anthocyanins are used as natural food colorants, and as potential pharmaceutical ingredients that give various health benefits. Anthocyanins possess antibacterial and antioxidative qualities that have the ability to improve visual and neurological health and…

Measuring Melanin and Hemoglobin levels of Skin Samples

Posted on: August 25th, 2022

Background/Applications: Human skin measurements apply to many industries and field studies with differing analyses in absorbance, transmission, and or reflectance. In this experiment, we tested the absorbance and reflectance of skin samples to analyze skin pigmentation and protein structures. The skin pigmentation studied in this experiment was melanin. Melanin is mainly located in the epidermis…
