Description of the Course
Learn how to estimate uncertainty in chemistry for ISO/IEC 17025:2017 accredited testing labs. This course is best suited for chemical testing labs that use HPLCs, GCs, and MS. The processes taught in this course are based on the JCGM 100:2008 (GUM) guide, the EURACHEM QUAM:2012 guide, and ISOBudgets procedures. This course includes 17 lecture videos, 11 demonstration videos, PowerPoint slides, and an Excel uncertainty calculator. It requires 11 hours to complete the course and a training certificate will be issued upon completion of the course.
Just watch the videos, follow the instructions given in the demonstration, and start estimating uncertainty.
Time to complete: 9.5 hours
