Analytical laboratories face many challenges when analyzing contaminants such as Pesticides, PFAS, mycotoxins in complex matrices. These samples often require time-consuming sample prep and regular maintenance of the analytical technology.
Due to PFAS persistence in the environment and potential health risks, regulations have been undergoing constant change and refinement.
With our extended portfolio of cannabis testing products featuring best-in-class sample homogenization platforms, ICP-MS, LC/MS-MS, Headspace-GCMS, UHPLC and FTIR instruments and consumables, we help drive analytical best practices and operating procedur
PFAS matrix-induced contamination poses various challenges for analytical laboratories, from the risk of achieving low detection limits and lab downtime.
PFAS compounds are ubiquitous throughout the environment and accumulate everywhere, including in the lab.
As per- and polyfluoroalkyl compounds become more prominent, the US Environmental Protection Agency (EPA) are developing more stringent regulations for PFAS monitoring.
Stricter regulations demanding lower detection limits, increased throughput and efficiency demand that labs need an LC/MS/MS solutions that offers robust and reliable performance while ensuring efficiencies.
When examining complex compounds like PFAS, pesticides, and mycotoxins using LC/MS/MS in challenging matrices, laboratories encounter issues such as system contamination, matrix effects, and the laborious task of source cleaning.
The PerkinElmer QSight LC/MS/MS is used for many applications, including forensic toxicology.
