If you are looking for a proficiency test and need a participation for a specific analyte/s or matrix, from TestQual we can organize a Custom Proficiency Test that fits what you are looking for:
All our PTs are organized according to the ISO 17043:2010 and we have the required experience to make the PT fit exactly to what you want. To organize it we would gather all the information about what you need and then prepare a draft protocol, which we would send it along with a quote so you can check that the PT would fit exactly what you needed.
You can get your quote without compromise by contacting our team through:
