A Green Analytical Method for Simultaneously Determining Plasticizers Residues in Honeys from Different Botanical Origins

Ultrapure water from a Milli-Q® water purification system was tested for PFAS according to the draft EPA 1633 method. None of the 40 PFAS compounds tested were detected in the ultrapure water produced by a Milli-Q® IQ 7000 system fitted with a LC-Pak® polisher at the point-of-dispense, making it suitable for the most sensitive PFAS analyses by LC- MS/MS.

Deriving antibodies from plasma products involves several steps, typically starting from the collection of plasma and ending with the purification of the desired antibodies. These are: plasma collection; plasma pooling; fractionation; antibody purification; concentration and formulation; quality control; and packaging and storage. This process results in a purified antibody product that can be used for therapeutic purposes, diagnostic tests, or research. Each step is critical to ensure the safety, efficacy, and quality of the final product. Applications of AI/GenAI in many of these steps can significantly help in the optimization of purification and yield of the desired antibodies. Some specific use-cases are: selecting and optimizing plasma units for optimized plasma pooling; GenAI solution for enterprise search on internal knowledge portal; analysing and optimizing production batch profitability, inventory, yields; monitoring production batch key performance indicators for outlier identification; monitoring production equipment to predict maintenance events; and reducing quality control laboratory testing turnaround time.

A recent study measured stress and reproductive hormones in three stocks of free-ranging bottlenose dolphins inhabiting different natural salinities across the Gulf of Mexico, with hormones extracted from the blubber of 82 remotely biopsied dolphins and quantified using ultrahigh-pressure liquid chromatography (UHPLC) coupled with orbital ion trap fusion mass spectrometry.

This note demonstrates efficient PFAS extraction from contaminated surface water using automated mixed-mode µSPEed® cartridges and Tecan's Resolvex® Prep.
