[Analysis Case] Evaluation of Hydrogen Concentration in Hydrogen Water

It is possible to measure the hydrogen concentration in solutions such as hydrogen water.

Hydrogen water is said to be able to remove active oxygen in the body, and attention is being drawn to its antioxidant effects. However, the amount of hydrogen that dissolves in water is minimal, and when left in the air, hydrogen gradually escapes. Additionally, because hydrogen is a very small molecule, it is known that some storage containers cannot maintain it for long periods. Therefore, the choice of storage container and method is considered important. This case presents the results of a GC (TCD) analysis showing how much hydrogen has escaped from hydrogen water transferred to a paper cup compared to a pouch-type storage container.

[Analysis Case] Impurity Evaluation of Crystalline Si Solar Cells

Trace analysis of metallic elements and atmospheric component elements.

We propose a method for evaluating the control of impurity levels required in each process from substrate growth to cell formation of crystalline silicon solar cells, using high-sensitivity analysis for element concentration measurement. Metal elements can be measured at concentrations below ppb, and atmospheric component elements containing hydrogen can be measured at concentrations below ppm. Measurement methods: SIMS, ICP-MS, etching, disassembly Product field: Solar cells Analysis purpose: Trace concentration evaluation, product investigation For more details, please download the materials or contact us.
