This is a special report on the automatic analysis of trans fatty acids.
At LECO Japan, we will pick up samples that are expected to enhance the precision, efficiency, and safety of your analysis operations using LECO's analytical instruments, and we will present them as a special report. Please take a look. If you would like to know whether similar samples can be applied, please feel free to contact us.
Suitable for relative comparison of flat samples such as printed circuit boards! Introducing the analysis flow of liquid samples and solid surfaces.
We would like to introduce a case study of ion chromatography analysis conducted by our company (solid surfaces). Solid surfaces can also be measured using ion chromatography by extracting them into a solution. Additionally, average data can be obtained for sample surfaces larger than a few centimeters, making it suitable for relative comparisons of flat samples such as printed circuit boards. You can view the analysis flow for liquid samples and solid surfaces by downloading the PDF below. 【Overview of Liquid Sample Analysis】 ■ Liquid samples are introduced into the device for measurement after solution preparation such as dilution and filtration. ■ Measurement results are reported in solution concentration [mg/L]. *For more details, please refer to the PDF document or feel free to contact us.
It is possible to analyze cation components in liquid samples.
As electronic devices are increasingly used in various everyday locations, ensuring the reliability of products has become important. Since it is possible for the copper used in the wiring of printed circuit boards to migrate and cause defects in high temperature and high humidity environments, it is crucial to evaluate the components that promote migration. This case study introduces an example of quantitative analysis of cation components eluted from printed circuit boards using ion chromatography (IC). Thus, IC is an effective method for evaluating the corrosion components on the surface of solid samples.

Qualitative and quantitative analysis of gas components in batteries.
The electrolyte of lithium-ion secondary batteries is known to decompose and gasify due to repeated charging and discharging. By using GC-TCD and GC/MS, the decomposed gas components can be detected with high sensitivity. GC-TCD can analyze the composition ratios of eight components (H2, O2, N2, CO, CH4, CO2, C2H4, C2H6), while GC/MS can qualitatively analyze various decomposition products. We also support gas analysis in not only laminate-type cells but also coin-type and prismatic cells, as well as cells using ionic liquids.
Surface property measurements of pharmaceutical raw materials, powders, thin films, and fibers with unprecedented high sensitivity!
The diversifying powder technology, particularly solid pharmaceutical raw materials, is pressing the need for a wide range of high-precision chemical property measurement techniques regarding components and structures. The IGC inverse gas chromatography has been developed as a surface property measurement technique using gas for the study of surface properties of fine particles, thin films, and fiber materials. SEA measures the physicochemical properties of pharmaceutical materials, specifically the surface free energy of powders and acidic/basic parameters, which are crucial factors affecting many substances' products and manufacturing processes, with high sensitivity that was previously impossible with conventional methods. SEA has been developed as a practical device through collaborative research with pharmaceutical research institutions and companies, based on techniques that some researchers have traditionally spent time and effort on, and it performs sample measurements in a set humidity environment completely automatically from sample injection to data processing.

Automating water quality management by simultaneously measuring nitrite, nitrate, and phosphate in seawater from shrimp farms using ion chromatography.
The concentrations of nitrite, nitrate, and phosphate in the seawater of the shrimp farm were measured using an ion chromatograph with a conductivity detector and a UV/VIS detector after chemical suppression.
Introducing a technique for creating a calibration curve for ion chromatography that covers a wide concentration range in a single measurement.
In ion chromatography with a conductivity detector and suppressor, it is often the case that the calibration curve is not actually linear. Particularly when the calibration curve needs to cover a wide concentration range, applying multiple calibration curves for different concentration ranges can lead to more accurate measurement results. By using MagIC Net software, multiple calibration curves can be created in a single measurement. This means that the optimal calibration curve for all ions is applied, improving the accuracy of the measurement results. This method can be applied to environmental waters such as tap water, seawater, and rainwater.
