Preparation Process

High-Precision Preparation for Valid Analytical Results

Key Points:

  • Executed by experienced technical personnel

  • Adhering to standardized preparation methods

  • Utilizing appropriate and calibrated equipment

  • Ensuring samples represent as-received conditions

The processes of size reduction and sample division are conducted under stringent temperature and technical controls to maintain the chemical and physical integrity of your coal prior to laboratory testing.

Technical Preparation Stages

  • Air Drying

    Natural drying or controlled oven drying to achieve moisture equilibrium.

  • Crushing & Grinding

    Size reduction utilizing clean crushing and grinding machinery.

  • Mixing & Dividing

    Homogenizing and splitting samples to obtain sub-samples that remain representative.

  • Final Sample Preparation

    Preparation of final samples for laboratory analysis, client archives (split sample), and reserve (umpire sample) as a continuation from mine to port.

Standards & Methodologies

  • International Methods Our operations are conducted in accordance with ASTM, ISO, and other recognized international standards.

  • Standardized Equipment Utilizing increment collectors with dimensions precisely tailored to the coal top size to eliminate bias.

Our team is prepared to assist with your inspection requirements through processes that are efficient, accurate, and fully compliant with international standards
