What does having PurityPlus primary / certified standards mean?

PurityPlus® Specialty Gases offers several grades of calibration gas standards – Custom Mixtures, Certified Standards, and Primary Standards to meet the level of accuracy for your laboratory or production process. All PurityPlus® Specialty Gases are custom-mixed and analyzed, and then properly labeled in one of our independently audited laboratory facilities. Each PurityPlus® Production facility conforms to a strict set of quality-assurance measures and standard operating procedures. Each of these labs have been thoroughly inspected, certified and documented to be compliant with FDA, DOT, OSHA, and EPA requirements - among others - by AsteRisk, a globally known, reputable, independent certification company headquartered in the U.S. 

Exposure to hazardous chemicals results in steep fines, penalties, and a compromised workforce. PurityPlus® Specialty Gases meets regulations and ensures compliance with all primary and certified standards.
