2. Shimadzu: Analysis of Stain-like Deposits on the Surface of Metal Machined Parts for the Transportation Industry Using the AIRsight Infrared/Raman Microscope
- application
User Benefits
- AIRsight makes it easy to quickly switch between infrared and Raman measurements without moving the target.
- Materials up to 40 mm thick can be measured directly and non-destructively.
- Raman spectroscopy is ideal for measuring micron-scale areas and rough surfaces.
Introduction
When manufacturing metal machined parts, anti-rust oil or cleaning fluid from machine tools may remain on metal parts, potentially leading to stain-like deposits. These stains can cause issues, such as reacting with lubricating oil or causing poor plating adhesion. This Application News presents a case study of measuring stainlike deposits found on the surface of metal machined partsfor the transportation industry using the infrared-Raman microscope AIRsight.
Conclusion
The analysis of stain-like deposits discovered on the surface of metal machined parts for the transportation industry using AIRsight was introduced. Raman spectroscopy allowed the qualitative identification of the stain components, which was difficult with infrared spectroscopy due to the surface's unevenness. AIRsight is very useful for the qualitative analysis of unknown samples by allowing rapid switching and measurement of both infrared and Raman spectroscopy without moving the sample. Additionally, it can measure thick samples like metal machined parts non-destructively.
3. Agilent Technologies: Quantitative Analysis of MEA-Triazine Hydrogen Sulfide Scavengers Through Innovative Transmission FTIR Spectroscopy

The Agilent Cary 630 FTIR spectrometer with DialPath module: transmission FTIR with variable path lengths
Abstract
A common contaminant in oil and gas extraction is hydrogen sulfide (H2S). Monoethanolamine-triazine (MEA-triazine) is one of the most used scavengers for H2S. Industrially, there are many challenges in measuring MEA-triazine concentration in aqueous solutions. This application note aims to develop a mid-infrared (mid-IR) method using an Agilent DialPath transmission module to measure the concentration of MEA-triazine in aqueous solutions. The analytical method described meets the requirements for quantifying MEA-triazine with different solvents, providing time savings, ease of use, and reduced susceptibility to pipetting errors due to viscosity.
Conclusion
The Agilent Cary 630 FTIR spectrometer with DialPath module proves to be a highly effective, accurate, and user-friendly method for the quantitative analysis of MEA-triazine in aqueous solutions. The technique's excellent linearity and robustness against additives such as MeOH and IPA highlight its reliability. The DialPath module's innovative design simplifies the measurement process, enhances sample throughput, and reduces common issues such as leaks and air bubbles. This method offers a significant improvement over traditional analytical techniques, providing a practical solution for both field and laboratory measurements in the oil and gas industry.
4. Metrohm: Quantification of water in lactose with the OMNIS NIRS Analyzer
- application
Fast, non-destructive determination of water with NIRS
Lactose is an important pharmaceutical product. Approximately 60% to 70% of pharmaceutical dosage forms contain lactose [1], and it is one of the largest pharmaceutical excipients by volume. Lactose can be used as a bulk filler for pharmaceutical tablets, as a binder to provide more strength to a dosage form, and it can also be added to facilitate the flow of a formulation during the production process. Moisture in lactose is undesirable at high levels as it causes the material to become sticky and bind to itself, forming hard clusters that may be difficult to break apart. USP specifies the water content range in lactose monohydrate from 4.5 % to 5.5 % [2]. The analysis of water in lactose is usually done with time-consuming methods. Near-infrared spectroscopy (NIRS) is a faster alternative. This Application Note shows the determination of water content in lactose with NIRS.
CONCLUSION
This Application Note demonstrates the feasibility to determine water content in lactose quickly and easily. NIR spectroscopy offers users a fast, cost-effective, and highly accurate alternative to other standard testing methods. Additionally, NIRS analysis is nondestructive, completely reagent-free, and gives results in only a few seconds.
