Cross-fractionation Analysis (CFC) is performed by a Polymer Char’s CFC Instrument, developed to measure the Bivariate Distribution by analytical Temperature (TREF) or Thermal Gradient Interaction Chromatography (TGIC) fractionation and subsequent online Gel Permeation Chromatography (GPC) analysis of the fractions, obtaining 3D plots as well as the recovered TREF or TGIC and GPC profiles, in a single analysis by using an Infrared (IR) detector (IR5).
The polymer is fractionated by crystallinity using a TREF or TGIC analysis at increasing temperature steps, that can be taken at any temperature (including sub-ambient), and fractions are automatically injected into GPC columns.
The following are some results of analyses performed by CFC:
These detectors are also used in some of our TGIC analyses:
The IR6 Detector is the latest IR Detector developed by Polymer Char with same capabilities and features than IR5 detector and the additional capability of measuring carbonyls group in the band of 1740 cm-1. IR6 Detector is recommended for users willing to analyze polyolefin type EVA, EBA, and others with carbonyls group present in IR band above.
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 include.
|CFC (Price/Sample)||First Sample||Additional Samples|
|Standard (up to 25 steps)||1.214€||1.010€|
|Calibration for Chemical Composition||186€||0€|
|Crystallization 0,1 (room temperature)||364€||303€|
|Crystallization 0,1 (subambient)||971€||808€|
|Minimum sample amount||>2 g|
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 firstname.lastname@example.org.
Please send an email to email@example.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 firstname.lastname@example.org
Samples should be shipped to:
Polymer Characterization S.A.
Valencia Technology Park
Gustave Eiffel 8
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 2 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.
