Application Notes: Polymers
Rapid Extraction of Pesticides from Strawberry CRM
New sorbent for water mitigation in rapid automated extraction and UPLC MS/MS analysis of pesticide residue from a strawberry.
Polymer branching analysis by SEC-MALS-IV
Branching impacts polymer properties such as rheology and stiffness. This note explains the analysis of branching ratio vs. molar mass, accomplished by SEC-MALS( -IV).
A Rapid, Simple, and Efficient Extraction Method for Additives in Plastics
• The EDGE extraction system is fast, automated, and highly flexible. • Case studies using the EDGE® extraction system.
Characterization of Hydroxyethyl Starch Using Gel Permeation Chromatography
In this note, the molecular weight averages and molecular weight distributions of two hydroxyethyl starch (HES) samples were successfully demonstrated.
Analyses of PFOS and PFOA Precursors in Textile Products
To address environmental concerns that may arise from PFOS and PFOA, two GC–MS methods–PCI-SIM and EI-MRM–were optimized for detection of PFOS and PFOA precursors.
