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

The concentration of ethanol in hand sanitizer was determined using a calibration developed with an automated ATR sampling accessory.
