Intrinsic Viscosity Analysis

Overview

 

This service provides the Intrinsic Viscosity (IV) of any polymeric material, including challenging ones such as high and ultrahigh molar mass polymers.

The viscosity test is performed in Polymer Char’s Intrinsic Viscosity Analyzer (IVA), which is compatible with any organic solvent such as decalin, tetralin, tri-chlorobenzene (TCB) and ortho-dichlorobenzene (o-DCB) among many others. Dissolution and analysis temperatures can be set independently, from ambient temperature to 200ºC, so that a wide range of polymers can be analyzed, even the most crystalline ones.

A study conducted by Polymer Char with different polymers in various solvents – PAN (polyacrylonitrile) in DMF (N,N-dimethylformamide), PET in phenol:o-DCB, PLA in TCB, and polyolefins in TCB and o-DCB – shows that all the intrinsic viscosity results obtained with IVA are in good agreement with the standard methods used as reference (compared to IV obtained with the traditional glass capillaries of the Ubbelohde type ISO 1628-3:2010 f.i.).

Analytical Services Frequently Asked Questions


The fractionation service is available thanks to the Instruments PREP mc2 and PREP C20, capable of fractionating samples by molecular weight or by composition (TREF or CRYSTAF). Please visit the link Preparative Fractionation for more information.

The resulting fractions are later analyzed by the corresponding technique (GPC or TREF/CRYSTAF) to check the good performance of the fractionation process. Finally, the physical fractions are sent back to the customer by courier service as well as the analysis results of the fractions, so the customer can check the separation.

For most of our analyses, you will receive a summary of the results along with an Excel file. However, the type of data and report form depends on the analytical service made. For specifics about the information sent, contact analyticalservices@polymerchar.com.

Please send an email to analyticalservices@polymerchar.com and we will be pleased to help you.

To order any analytical service, please fill in the Analytical Service Request Form. Provide all the information available about the samples to be analyzed. Sent forms will be processed as formal orders for Polymer Char records. All the information provided is considered confidential information.

If a previous quotation is required, please do not hesitate to let us know by sending an email to analyticalservices@polymerchar.com

Samples should be shipped to:

Polymer Characterization S.A.
Valencia Technology Park
Gustave Eiffel 8
Paterna, Valencia
E-46980, Spain
Attn.: Analytical Services Department

We highly recommend to use courier service instead of post mail to ensure your samples arrive in good condition.

The standard response time is 3 weeks. This time is approximate and depends on the analysis queue in the laboratory at the time of the order. Polymer Char will inform the customer at the time of the order in case the response time is expected to be longer.

Urgent services (results sent within 10 days from the samples receipt) might be requested with a 50% surcharge. Please consult with Polymer Char the availability of this service and delivery time at the time of the order.

Please refer to our Analytical Services Terms and in the first chapter, you will find the necessary amount for each technique.
