What your CDS calibration settings actually compute: Empower, Chromeleon and OpenLab.
What Empower, Chromeleon and OpenLab calibration settings compute: fit types, weighting, origin handling and fit statistics, with a worked example.
TNI calibration requirements for environmental laboratories.
NELAP accreditation runs on the 2016 TNI standard, and its chemistry module sets the calibration rules your lab is assessed against. DoD work adds a second, tighter layer.
ISO/IEC 17025 calibration and traceability: what auditors look for.
ISO/IEC 17025 does not tell a chromatography lab how to build a calibration curve. It sets what the lab must be able to prove about one, and the assessor’s questions follow the clauses.
Calibration vs. calibration verification: ICAL, ICV and CCV explained.
Calibration vs. calibration verification: what ICAL, ICV and CCV each prove, how often to run them, and their acceptance limits.
Should a calibration curve go through zero? When forcing it is justified, and when it is a finding.
Should a calibration curve go through zero? How to test the intercept, and when forcing the origin becomes an audit finding.
Calibration curve weighting: when to use 1/x and when to use 1/x².
When to use 1/x or 1/x² calibration curve weighting, how to test your data for it, and how to document the choice.
Linear vs. quadratic calibration curves: how to choose, and how to defend the choice.
A quadratic calibration curve models a detector whose response is genuinely curved. The regulations allow it only with more standards and tighter conditions, and a better fit alone does not justify it.
Intelligent data assimilation.
A software platform enabling users to evaluate data through a prodigious Calibration Intelligence Dashboard.
Bold science.
Strengthening data quality, from the analyst’s bench to the auditor’s review.
