1. Agilent Technologies: Economical Carbon Enhanced Plasma Ionization: Substituting Acetic Acid with Carbon Dioxide

• Application

Cost-effective method suitable for routine analysis of Australian grain export cargoes by Agilent 8900 ICP-QQQ

Conclusion

A custom process was developed for mixing carbon dioxide in argon and supplying it to the plasma of the Agilent 8900 ICP-QQQ. The study showed that the use of gaseous carbon for plasma ionization enhancement provided advantages over traditional liquid sources of carbon, such as acetic acid, in terms of cost and performance. The scalability of the gas supply system can be enhanced by increasing the size of the ballast tank, enabling the efficient use with multiple ICP-MS instruments. This optimization would lead to more cost reductions.

The use of CO2 in Ar, supplied from a ballast tank, ensures easy and rapid adjustment of the carbon composition of the plasma with minimal flush out times, addressing a common challenge associated with liquid carbon sources. Carbon was shown to enhance the signal of key elements such as arsenic in the plasma, while maintaining the sensitivity of other elements. The carbon buffering effects of the modified plasma enable the quantification of low concentrations of analytes in food samples, such as grains. Adding carbon to the plasma if especially useful for samples that have variable carbon content, as it compensates for any sample differences and minimizes the variability from easily ionized elements. Based on our experience, the 8900 ICP-QQQ has proven to be a highly efficient and cost-effective tool for analyzing export grain cargoes, especially in a high-throughput laboratory setting.

2. Shimadzu: LA-ICP-MS Software

• Brochures and specifications

By combining this software with Shimadzu ICPMS Series Systems connected to a laser ablation instrument, sample measurement and data output in a format compatible with imaging data analysis software are possible.

Batch registration of line scan information

• The sample information can be entered using the image of the irradiation area (Number of lines x irradiation time) set by the laser ablation instrument. Reduce the time and effort required to enter information to 1/10 or less*.

*When 10 or more lines are registered

Data output per sample

• The acquired data is output as one data file per sample. Prevents missing or mixed data when multiple line data are selected and output.

Supports imdx format
The data of the output imdx format can be read as it is by Shimazu Mass Spectrometry Imaging Data Analysis Software IMAGEREVEAL™ MS. You can start the analysis immediately without converting the data.

3. Agilent Technologies: Quality Control of Lithium-Ion Battery Electrolytes and Solvents by UV-Vis Spectroscopy

• Applications

Color measurements and safe chemical handling using an Agilent Cary 3500 Flexible UV-Vis with Cary Sipper pump

Abstract: Ensuring the quality of electrolytes used in lithium-ion batteries (LIBs) is crucial for maintaining the safety, performance, and longevity of these energy storage devices. LIB electrolytes consist of lithium salts dissolved in organic solvents. Any discoloration (yellowness) of these near-clear solutions can indicate contamination or degradation. Industry methods such as ASTM D5386-16 Standard Test Method for Color of Liquids Using Tristimulus Colorimetry can be applied to assess the quality of electrolytes by conducting instrumental color measurements using UV-Vis spectroscopy. Given the low absorbance of colorless-to-near-colorless liquid samples like LIB electrolytes and solvents, a highly accurate and sensitive UV-Vis spectrophotometer is essential.

This study demonstrates an effective quality assessment method for LIB electrolytes and solvents using the Agilent Cary 3500 Flexible UV-Vis spectrophotometer fitted with the optional Agilent Cary Sipper flow cell pump. The method is suitable for production quality control of hazardous samples, ensuring safe sample handling, high throughput, and high quality results for production-critical chemicals.

Conclusion: The Agilent Cary 3500 Flexible UV-Vis spectrophotometer provided accurate and precise color measurements for colorless to near-colorless LIB electrolytes and solvents in accordance with the ASTM D5386 standard method. Advantages of the Cary 3500 Flexible method and findings based on the data set include:

• Hazardous samples were introduced directly into a 10 mm path length flow cell using the Cary Sipper pump, ensuring user safety and high sample throughput without compromising data quality.
• The superior sensitivity (high signal-to-noise ratio) of the Cary 3500 combined with Agilent Cary WinUV Color application software enabled the reliable monitoring and control of electrolyte properties by analyzing light absorption in the visible spectrum.
• Higher Pt-Co color (APHA) values of the used LIB electrolytes compared to fresh samples suggested a deterioration in quality due to the color changes.
• Color measurements could be used to improve the quality control of LIB electrolytes and solvents by identifying discoloration—an indication of contamination or degradation that could affect battery performance.
• This effective method could be implemented in both manufacturing QC settings and R&D laboratories.

QC color measurements using the Cary 3500 Flexible UV-Vis would ensure that only high-quality electrolytes are used in the production of LIBs, enhancing their safety, efficiency, and durability.

Thermo Scientific iCAP PRO Series ICP-OES

Discover more with the SemiQuant feature of Thermo Scientific Qtegra ISDS Software

Semi-quantitative analysis can be carried out by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and involves determining the relative concentrations of elements in a sample rather than obtaining precise quantitative measurements. The semiquantitative approach is often used for rapid screening of samples or for identifying elemental composition trends rather than obtaining exact concentrations. Interpretation of semi-quantitative analysis may involve identifying major and minor elements present in the sample, detecting elemental trends or patterns, or comparing the elemental composition of different samples.

What is SemiQuant?

The SemiQuant feature within the Thermo Scientific™ Qtegra™ Intelligent Scientific Data Solution™ (ISDS) Software is a data acquisition tool leveraging Artificial Intelligence and employing deep neural networks to simplify the complex process of intra- and inter-element correction, selecting only non-interfered peaks, automatically. This supports fast screening of samples to gain insights into sample composition. It can be a useful aid in method development and enables the collection and archiving of approximate elemental concentrations of a broader range of analytes in the samples in case they can be of interest at a future date. Its unique implementation allows users to get a good understanding of the presence of certain elements in their sample and also offers the concentration amount and a level of confidence for the given concentration to allow the best possible interpretation of the results.
