NSI Lab Solutions Inc. is an ISO accredited certified reference material producer and proficiency test provider based in the USA. With over 20 years of experience manufacturing custom solutions for environmental, food, agriculture, and pharmaceutical laboratories, NSI has a flawless track record of providing exceptional quality PT samples above and beyond current required standards, so you can be confident in the results of your testing. And PT reports may be sent to multiple accrediting authorities at no extra charge.

If you need results quickly, a PT Express test from NSI Lab Solutions can help you to

  • Demonstrate the proficiency of an analyst so you can assign him or her to new, important projects
  • Demonstrate corrective action to your accrediting authority after a poor result on a formal PT sample
  • Demonstrate proficiency for an initial accreditation.

If the proficiency tests or quality control materials available don’t meet your needs, NSI can design a custom solution for you that does. Send us an email with your requirements (required no. of units, analytes including CAS no. if applicable, concentrations including units, solvent or matrix, and the validation or documentation required) and we’ll get back to you with a quote ASAP.

As authorized NSI Lab Solutions distributors, we handle importation and customs clearance to the EU from the US for you. You also gain access to our excellent, personal customer and scientific support.
