When a component fails in the field, the pressure to identify the cause quickly is real. Production may be on hold. A customer is waiting. The temptation is to guess. Failure analysis exists to replace the guess with data, and understanding the process helps you get useful results faster.
Japanese manufacturers exporting electronic and electrical equipment to the European Union are required to demonstrate compliance with the RoHS Directive (2011/65/EU and its amendments). The testing requirements are more nuanced than a single XRF scan, and getting the documentation wrong can delay market entry.
ICP-OES (inductively coupled plasma optical emission spectrometry) is the standard method for quantifying trace metals in water at concentrations down to parts per billion. If you are managing process water, monitoring a well, or preparing discharge data for a local authority, understanding what the method does and does not measure will help you commission the right test.
Full JIS compliance testing is expensive and time-consuming, and submitting a prototype that has not been through a preliminary validation round is a common way to waste both. A structured prototype validation run identifies the most likely failure points before you commit to tooling or a formal submission.
Japan's Ministry of Health, Labour and Welfare (MHLW) has published indoor air quality guidelines for 13 volatile organic compounds, including formaldehyde, toluene, xylene, and ethylbenzene. These guidelines apply to newly built or renovated buildings and are increasingly referenced in building handover documentation and facility management contracts.
Scanning electron microscopy and energy-dispersive X-ray spectroscopy are two of the most frequently requested techniques at Drift Core Lab, and also two of the most frequently misunderstood. Clients sometimes expect SEM to give them a composition result, or EDX to show them a fracture surface. Understanding what each instrument actually does will help you commission the right analysis.
