Webinar: Soil Laboratory Internal Quality Control
Date: 6 August 2026
Time: 14:00 to 16:00 (UTC+2)
Modality: Virtual
Language: English
Webinar summary
Internal soil laboratory quality is essential for ensuring that analytical results are accurate, reliable, and fit for purpose. A robust quality management system increases confidence in laboratory data, supports informed decision-making, and improves operational efficiency.
Quality control focuses on monitoring the quality of routine analytical results through the use of internal control samples and statistical evaluation. These data can be compiled into control charts to assess laboratory performance and identify trends over time.
Quality assurance provides a broader framework for maintaining and improving quality through activities such as the development of Standard Operating Procedures, personnel training, equipment calibration and maintenance, and the regular review of laboratory processes. Together, quality control and quality assurance support the consistent production of high-quality results.
This webinar will present practical examples and best practices to help laboratories strengthen their quality management systems and improve overall laboratory performance.
Agenda
The webinar will be a two-hour session for one day focusing on internal laboratory quality. It will involve three main topics: quality control, quality assurance, and functional examples of the best practices.
-
Quality control focuses on the establishment of control samples, how to implement within routine analysis, and review the data quality.
-
Quality assurance focuses on laboratory quality processes and reviewing quality control over an extended period.
-
Real and functional examples will be presented and discussed to highlight the ease of implementation and advantages that quality control and assurance can deliver.
