Proficiency Testing Services
SigSci’s ISO/IEC 17043:2010 (ISO 17043) accredited proficiency test (PT) programs are tailored to client operations and objectives. The PTs provide performance data for specific tests, accounting for test method sensitivity and specificity, as well as variables such as sample matrix and preparation method.
SigSci’s PT accreditation covers environmental matrices on various collection media, and in samples of powders, liquids, soils, sludges, swabs/swipes and vegetation covering Chemical Warfare Agent-related chemicals, Toxic Industrial Chemicals, Toxic Industrial Materials, Explosives, Biological Pathogens, and Select Toxins.
