We evaluate the isotope ratio by measuring specific mass numbers using ICP-MS.
Isotopes with different mass numbers exist for atoms. In isotope analysis services, the ICP-MS (Inductively Coupled Plasma Mass Spectrometer) is utilized to measure based on mass numbers, allowing for the measurement of isotopes for each element. Based on the measurement results, it is possible to determine and evaluate the isotope ratios.

basic information
**Features** ● Measurement by mass number using ICP-MS ICP-MS detects signals by mass number. In the case of lead, by measuring mass numbers 204, 206, 207, and 208, it can be evaluated as 204Pb, 206Pb, 207Pb, and 208Pb. ● High sensitivity measurement ICP-MS allows for measurements at low background levels, enabling detection at μg/L (ppb) concentration levels in liquid. ● Interference suppression with carrier gas By using the collision reaction cell method, it is possible to suppress interference in complex matrices. Therefore, measurements can be conducted even with high matrix samples.

Company information
Our main business is providing technical services to evaluate the reliability of developed products. We not only provide evaluation data in accordance with standards and regulations, but also propose optimal methods, conditions, and equipment for evaluation purposes, as well as design and manufacture original equipment and jigs for non-standard evaluations. Additionally, we handle three evaluation techniques—measurement, testing, and analysis—comprehensively, allowing us to offer complex services that span diverse equipment and suggest more multifaceted evaluation methods.
