Chemical analysis
Accredited in accordance with the requirements of ISO 17025, the laboratory performs mineral and raw material analysis at a high professional level using selective and modern instrumental analysis methods.
Sample preparation
The accuracy of the test results depends on the sampling and preparation. From the moment the sample is received in the laboratory, “True TRC” LLC pays attention to the preparation of the sample according to the instructions. The rock and drill coresamples shall be crushed to -10 mesh (1.7 mm) for testing in accordance with the standard requirements andpulverizedtherepresentative sampleinto 150 mesh of at least 95% through blending and splitting. (106 microns).
In the daily practice of sample preparation, clean sand is used between samples, and the cost is not included in the cost of the test. The quality of the sample preparation work is regularly checked in accordance with the quality management system procedures in our laboratory.
Sample storage
Test specimens are stored free of charge for 90 days after the results are obtained. If the customer wants to continue to store the sample, we provide a service to store the customer's sample in a safe and free from external contamination. Sample storage is registered in our laboratory system.
