Dear Ravi,

On behalf of Sibonisiwe Coal Laboratory Services and the team, I would like to thank you for the professional services you have rendered towards obtaining our SANAS accreditation. I would like to specifically thank you for the following:

1.       The professional advices you’ve given us after conducting the internal audits, that helped us a lot in clearing the grey area we always had and to rectify the hidden wrongs that we could not pick up ourselves.

2.       The professionalism displayed in conducting the validation of our methods. The SANAS auditing team was impressed with the way the our validations were done and the contents of the reports. For your information, all the methods you validated are now accredited.

3.       Accuracy in preparing the CRM’s, which were used in the validation of our test methods.

4.       The technical knowledge you have on the running of a laboratory helped us in preparing for the initial SANAS assessment, after which we were recommended for accreditation. Our clients are now impressed with the way we are running our laboratory.

You are free to use Sibonisiwe as reference.

Thank you once more and keep up the good work!!
