Analysis of Phosphorus in Resin by EDX　-Phosphorus Screening Analysis Kit for TSCA -

User Benefits

- The screening analysis package provides everything necessary for analysis including control samples and software. - EDX can simultaneously screen for phosphorus, RoHS elements, antimony (Sb) and chlorine (Cl). - EDX-7200 can measure phosphorus concentration in resin with high sensitivity.

Introduction

Phenol, isopropylated phosphate (3:1) (PIP (3:1)), is a phosphate compound with three phenyl groups that are isopropylated. It is widely used in resins such as polyvinyl chloride and polyurethane for the purpose of adding plasticity and flame retardancy. Due to directives in the Toxic Substances Control Act (TSCA), the U.S. Environmental Protection Agency (U.S. EPA) has begun regulating the manufacture, processing, and commerce of products and articles containing PIP (3:1). Energy dispersive X-ray fluorescence (EDX) can not perform qualitative or quantitative analysis of organophosphates, but it can analyze the concentration of phosphorus (P) as an element. Therefore, EDX enables screening analysis aimed at controlling total P concentrations in regulated organophosphate compounds. This application news introduces the flow of screening analysis of P using PCEDX-Navi software and examples of screening analysis of P in resins.
