Standard Gas manufacturing/Analysis

Hierarchy of Standard Materials

Product Class of Standard Gas is divided into Primary Standard, Master Standard and Certified Standard according to the method for manufacturing mixed gas and mixing accuracy of component gases.

Maintaining Traceability of Standard Substance

RIGAS PRMs ( RIGAS Primary Reference Materials)

Manufacturing in gravimetric method, the absolute measurement method,
in accordance with ISO G34 and ISO6142

Maintaining standards by comparative measurement with CRMs of home and abroad Standardization Organizations (KRISS, NMi, NIST, NPL, etc.)

RIGAS MRMs(RIGAS Master Reference Materials)

Manufacturing in gravimetric method, the absolute measurement method, in accordance with ISO G34 and ISO6142

Testing and certifying by comparative analysis with RIGAS PRMs in accordance with ISO 6143

CRMs for spread (Certified Reference Materials)

Testing and certifying by comparative analysis with RIGAS MRMs in accordance with ISO 6143
