Utilizing Infrared Spectroscopy at Air/Water Interface (July 15, 2022)

Semi-batch reactions offer several advantages over traditional batch reactions, such as greater selectivity of products, gradual addition of reactants for better process control, and the ability to isolate product as it is formed. 

Monitoring and Control of a Semi-Batch  Polymerization with Raman Spectroscopy

In this application note, we study a nicotine patch to reveal the active pharmaceutical ingredient (API) as well as the polymer layers encapsulating it via confocal Raman microscopy.

This application note describes a correlative Raman–scanning electron microscope (SEM) investigation of a lithium-ion battery cathode before and after hundreds of charge cycles. The technique provides an exceptionally detailed chemical and structural analysis of degradation processes on the nanoscale.


Correlative Raman Imaging for Battery Research

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

Automated Macro-Mapping a  Coating via Reflection Sampling

This application note demonstrates using ATR to examine the changes in surface orientation as a function of the distance from the injection point or gate.


Characterization of Surface Orientation  of a Molded Polymer by FTIR-ATR

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

Multiple Reflection, Variable Angle ATR for Optimized Data

In this application note, we discuss the implementation of offset phase locking using a digital phasemeter, and characterize the stability of phase locking two lasers.

Laser Frequency Offset Locking with Moku:Pro

Infrared reflection-absorption spectroscopy (IRRAS) is a powerful tool for the structural analysis of monolayers at the air/water interface.
