September 07, 2023

Liquid samples were analyzed by infrared using fixed pathlength transmission cells and ATR.

Perfect Pellet Making

May 12, 2023

A clear KBr pellet minimizes IR scattering and provides the highest quality IR sample spectra. Here, we review how to make the perfect pellet for your application.

Monitoring Crystallization of Oil via FT-IR-ATR

February 09, 2023

The crystallization of coconut oil was measured via FT-IR-ATR at 1-min intervals during a precision cooling ramp, using the MIRacle Peltier.

Chemical Imaging of Berry Seed Cross Section

October 13, 2022

A section of a fruit berry seed was chemically imaged with infrared spectromicroscopy revealing domains of phospholipid-rich regions from the cell walls of the seed’s skin.

Low-volume ATR Measurements of Oils

June 15, 2022

Using a low-volume, multiple reflection ATR, infrared spectra of new and in-service motor oil were collected. Example spectra are presented.

Detecting Solvent Impurities Via ATR

May 09, 2022

FTIR-ATR sampling was used to detect contaminants in acetone. By evaporating the solvent directly onto the ATR crystal, the impurities were easily measured.

Automated Macro-Mapping via Reflection Sampling

February 07, 2022

Using an automated FT-IR reflection sampling accessory, the surface of a polymer-coated aluminum film was analyzed. Results were used to investigate chemical uniformity.

Multiple Reflection, Variable Angle ATR for Optimized Data

October 11, 2021

Here, we explore the benefits of using a multiple reflection, variable angle attenuated total reflectance (ATR) instrument to generate the most informative spectral data. c

Non-destructive, Diffuse Reflection Measurements of Solids

May 05, 2021

A useful, non-destructive sampling technique for the analysis of non-particulate solids is demonstrated. Diffuse reflection and ATR spectra are compared.

Quantifying Ethanol in Hand Sanitizer via Automation

October 15, 2020
