Elemental analysis by aas and icp-oes precious metal analysis tamilnadu test house offers testing in precious metal like gold and silver by using fire assay method. Tamilnadu test house also analyse the gold and silver content in nanotechnology samples, collagen samples, ayurvedic products and animal house study samples. Trace metal analysis by aas and icp-oes trace metal analysis of elemental impurities is very critical for pharma products before market launch. The elemental composition of alien metals helps defining the product purity and quality. Metal contaminations have been observed in drugs expected for use by people and creatures. Drug articles incorporate dynamic pharmaceutical ingredient (api), excipients, drugs and dietary supplements alongside their ingredients. Some metals viz. Arsenic, mercury, cadmium and lead are lethal at low levels and ought to be checked to ensure safety of consumers. The source of metal impurities might be from those added to the process (such as catalyst) or those derived from the process itself, or maybe contaminants from input material or reagents. The usp under the general chapter (231) specifies the test procedure for identifying metal impurities such as aluminium, arsenic, iron, lead, and mercury. Usp (231) is a qualitative or semi quantitative limit test. It helps identifying the metallic impurities using sulphide ions which results in a coloured precipitate. The standard comparison assists in evaluating exceeding specified limits. The sample preparation schemes used in the analysis are:

The amount of residual solvents introduced while processing concentrates are determined by tnth with the help of certain validated testing methods. We monitor the ppm levels of solvents which help to identify raw materials & products that are free from harmful contamination.

Tamilnadu test house offers asbestos analyses in talcum powder, soil samples, and building materials or demolition debris. Asbestos is a naturally occurring silicate mineral which finds innumerable applications in construction and process industries. However, exposure to environments with high concentrations of asbestos can present occupational hazards. Asbestos is classified as group a, a known human carcinogen which cause lung cancer and mesothelioma and possibly gastrointestinal cancers in humans. Cosmetics can also pose carcinogenic hazards if not formulated with the appropriate ingredients. Talcum powder is one cosmetic ingredient which has been used for centuries. Its primary source is soapstone which is hydrated magnesium stearate with other mineral carbonates and silicates present in minor amounts. Talcum powders can also contain asbestos which is a known carcinogen. Due to its low concentration, its presence does not pose the serious risk due to inhalation but using it in cosmetics directly on the skin can cause cancer over years of regular use. Tamilnadu test house using x-ray diffractometer, to analyse the asbestos content and we can detect in ppb level of asbestos content.
