Chemical Composition Analysis by CRYSTAF

Overview

 

 

Crystallization Analysis Fractionation (CRYSTAF) is a technique used to measure the Chemical Composition Distribution (CCD) in polyolefins based on the segregation of crystals of different morphology or comonomer content by crystallizability. In this technique, separation and analysis are performed in a single step; the crystallization cycle, where the polymer solution is sampled and its concentration are analyzed at the same time that the temperature is decreasing for the crystallization by using an Infrared (IR) detector, IR4.  Concentration data obtained at each temperature sampled correspond to the cumulative curve of the Chemical Composition Distribution (CCD).

Detectors

These detectors are used in our CRYSTAF analyses:

IR4

IR4

The standard detector used on this analysis is a dual-wavelength infrared detector, which uses the principle of infrared absorption spectroscopy to measure the concentration and composition in polyolefins.

CRYSTAF Analytical Services Fees

To calculate your cost, please use the base amount (‘Standard’ in this case) and then add the corresponding amount as per any additional detectors or services you want to be used. Anything below 30ºC is considered "Subambient".

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.

You will receive the results in less than a week. If you plan to send more than 10 samples, please check with our lab, as the response time may be longer in this case.
This time is approximate, and it depends on the service queue in the laboratory at the time of the order. Polymer Char will inform the customer if the turnaround time is expected to be longer.

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