What Are the Key Parameters that SGS Uses to Test the Quality of Granular or Lump sulfur?

SGS uses several methods to analyze the quality of granular or lump sulfur. Some of the key parameters that are typically analyzed include:

1_ Sulfur content

The sulfur content of the sample is determined using one of several standard analytical methods, such as combustion analysis or inductively coupled plasma optical emission spectrometry (ICP-OES).


The presence of impurities, such as metals, ash, and organic matter, can affect the quality of the sulfur. These impurities are typically analyzed using techniques such as X-ray fluorescence (XRF), atomic absorption spectroscopy (AAS), or combustion analysis.

3_Particle size

The particle size distribution of granular or lump sulfur can affect its handling and storage properties. Particle size analysis is typically performed using techniques such as sieve analysis or laser diffraction.

4_Moisture content

Moisture can affect the handling and storage properties of the sulfur, as well as its sulfur content. Moisture content is typically measured using techniques such as Karl Fischer titration or loss on drying.


The color of the sulfur can be an indicator of its purity and quality. Color analysis is typically performed using visual inspection or spectrophotometry.

SGS has extensive experience in analyzing the quality of granular or lump sulfur using these and other methods, and can provide accurate and reliable results to help ensure the quality of the product.
