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

Excellent - well worth both the money and time.
I needed to develop a better understanding of expanded uncertainties and how to build error budgets. Most of the material or classes that I found did not contain enough rigor or examples to cover our products and processes; and as such, were of limited value. The agenda for this class focused on the chemical laboratory and included some of the analytical equipment we use, so I thought I’d give it a try. The resource guides and calculators saved me significant hours. The time savings alone justified the course fee. The course is well designed; builds in a logical format, is clear and easy to understand. The demos re-enforced the material covered. Rick is a good instructor and sticks to the material – he doesn’t wander off on tangents and confuse you. We have several product lines including gas calibration standards and chemical analysis of low level impurities in corrosive gases – which makes developing an error budget challenging. This course gave me several significant angles to pursue and the take away format will be put to use immediately. I also liked that this course was divided up into “bite sized pieces” which greatly improved my retention of the material. It was also way cheaper than taking a weekend course at PittCon.
