​CHS Refined Fuels Customer Sampling and Analysis Program

​Purpose:

​The purpose of this program to is to provide Cenex fuel customers with timely and accurate fuel analyses data.  This data will be used by CHS Technical Services, Refined Fuels Product Quality, and the CHS Lab to help resolve a customer’s concern regarding Cenex fuel quality.      

 

​Overview:

​This new site is being developed to allow Cenex fuel customers to conveniently submit refined fuels sample data, stay updated on the progress of their sample, and consume fuel sample results all in one place.  Currently, this system is only open to individuals with a CHS email address.  Our goal is to make this website available to all Cenex branded customers. 

Our expectation for CES’s and those with a CHS email address utilize this website to submit samples and receive results as opposed to submitting a paper form with your sample.  Local cooperative customers who don’t have access currently can still submit samples with the paper form and get results through email until a solution is found to grant them access.

As we enhance the system based on user feedback and the needs of our Cenex refined fuels network, you might notice changes and additions to the site.  Please feel free to visit the contact us section to leave feedback, ask questions, or offer suggestions.  

The information below outlines the technical details and laboratory process for the refined fuels sampling program.

Samples and Sample Retention

  1. A full quart sample of the fuel to be analyzed shall be sent to the CHS Laurel laboratory. The sample must be properly packaged and labeled 
  2. The sample shall be accompanied by a sample information sheet or an electronic sample information record. Samples received without this sheet or without pertinent information will not be analyzed. A minimum of 500 mls of sample is required for all testing to be complete. This does not include any special requests or reanalysis.
  3. Samples containing less than the required amount will be reviewed and certain tests may be marked Quantity Not Sufficient (QNS) on the sample result.
  4. Samples shall be retained for a minimum of 7 days after the Certificate of Analysis is sent by email to the customer.
  5. Analysis will be completed within 4 days from the login of the sample
  6. Special request analysis will be reviewed and performed as deemed necessary. Special request analysis will be completed within 4 days
  7. Reanalysis requests will be reviewed and performed as deemed necessary
  8. All data will be input into the CHS Laurel LIMS system and retained for 5 years
  9. A picture of a sample will be taken if impurities are present and will be attached with the CoA
