Gypsum Inorganic Content Analysis
Understanding gypsum inorganic content is crucial for industries that rely on quality and purity standards. Gypsum (CaSO₄·₂H₂O), a naturally occurring mineral, serves as the primary component of products like cement, wallboard, and fertilizers. Ensuring accurate analysis of its inorganic content ensures product consistency, regulatory compliance, and overall safety.
The process involves several stages: sample collection, preparation, digestion, and analysis using spectroscopic or chromatographic techniques. The aim is to measure the proportion of inorganic compounds accurately, especially calcium sulfate dihydrate (CaSO₄·₂H₂O), which defines gypsum purity. This service ensures that gypsum meets specific international standards such as ISO 14678 for chemical analysis and ASTM C319 for cementitious materials.
Proper sampling is critical, requiring a representative portion of the material to ensure accurate results. The sample must be dried under controlled conditions before undergoing digestion in an appropriate reagent like nitric acid. Digestion removes organic matter, leaving only the inorganic compounds for quantification. Spectrophotometric analysis or atomic absorption spectroscopy (AAS) are common methods used post-digestion.
The analytical process is sensitive to environmental factors and operator skill. Therefore, Eurolab employs stringent quality control measures during sample preparation and analysis. Our laboratories are equipped with state-of-the-art instrumentation including inductively coupled plasma optical emission spectrometry (ICP-OES) for precise measurements of metal ions present in the gypsum.
The final report details the total inorganic content, any trace elements, and impurities that may affect product performance or regulatory compliance. Compliance with standards like ISO 14678 ensures confidence in the quality of gypsum products across various sectors including construction, agriculture, and industrial applications.
