Elemental Analysis

BOC Sciences can provide comprehensive element analysis services for the pharmaceutical industry according to USP, EP or other analysis methods. Our services comply with global regulations such as the United States, the European Union, and Japan, or according to your special requirements. Pharmaceutical elemental analysis is very important for quality control and impurity control, including elemental pollutants, has always been a key issue in drug development and production. Understanding the element composition of raw materials, active drug ingredients, excipients or preparations helps to ensure product quality and purity.

Elemental analysis is a chemical analysis method for studying the composition of elements in organic compounds. It is divided into qualitative and quantitative. A method of determining the elemental composition and percentage of a compound by a chemical reaction. The former is called elemental qualitative analysis, and the latter is called elemental quantitative analysis. After a complete elemental analysis, the experimental formula of the compound can be calculated. Knowing the molecular weight of the compound, which can also fix the formula, supplemented by other methods known the structural formula.

Below is a list of our elemental analysis test services (include but not limited to the following):

Identify unknowns

Our team can learn from the experience of different sample technologies to identify the elemental composition.

We provide robust elemental analysis to ensure that traces are within acceptable limits.

Our scientists provide fast and professional solutions for analyzing problems encountered in samples analysis.

Quality control is especially suitable for routine analysis to ensure the high quality of medical products, safe pharmaceuticals and health care industries.

Proper sample preparation is essential to obtain reliable quantitative data. We select the most suitable technique for the sample from a series of sample preparation methods.

When our team analyzes food contact materials or pharmaceutical containers, the samples are used to support food or pharmaceutical packaging compliance to demonstrate that they meet with national and international standards.
