What is ISO 16014-3 – Distribution of polymers using SEC at low-temperature method about?

ISO 16014 discusses plastics. ISO 160143 is the third part of the ISO 16014 multi-series and discusses determining average molecular weight and molecular weight distribution of polymers using SEC at low-temperature method.

ISO 16014-3 specifies a method for determining the average molecular weight and the molecular weight distribution of polymers by size-exclusion chromatography (SEC) using an organic eluent at a temperature lower than 60 °C. The average molecular weight and the molecular weight distribution are calculated from a calibration curve prepared using polymer standards

Who is ISO 16014-3 – Distribution of polymers using SEC at low-temperature method for?

ISO 16014-3 on determining average molecular weight and molecular weight distribution of polymers using SEC at low-temperature method useful for:

Plastic products manufacturers
Plastic manufacturers
Quality control personnel
Testing laboratories

Why should you use ISO 16014-3–Distribution of polymers using SEC at low-temperature method?

Size-exclusion chromatography (SEC), also known as molecular sieve chromatography, is a chromatographic method in which molecules in solution are separated by their size, and in some cases molecular weight. It is usually applied to large molecules or macromolecular complexes such as proteins and industrial polymers.

ISO 160143 provides you with the method of determining the average molecular weight and the molecular weight distribution of polymers using size-exclusion chromatography (SEC) using an organic eluent at a temperature lower than 60 °C. ISO 160143 provides you guidance with reagents and apparatus required for the method.

ISO 160143 guides you with the procedure and helps you with data acquisition and data processing. ISO 160143 provides you guidance on the expression of results and test reports. ISO 160143 helps you with the important method of characterizing polymers.
