A Brief Overview of Gold Testing Labs in Tamilnadu

Tests for the presence of metal are required for most industries including food, pharma as well as research. Products are analyzed for trace metal and precious metal impurities. Testing is crucial to pharma products before launching to maintain quality and detect foreign materials. Multiple metals like arsenic, mercury, cadmium, lead, gold, and silver have been detected in drugs used for humans and animals.  The sources of these impurities might be from ingredients of the processes involved like catalysts or by-products of the process itself. Testing for gold and other metals is a prerequisite to a successfully launched product in the market. To test your product contact our NABL Testing labs in Chennai. 

Precious Metal Tests


Our NABL-accredited labs in Tamilnadu provide analysis options for various products ranging from nanotechnology samples, collagen samples, and ayurvedic products to animal house study samples. At our Gold testing Labs in Chennai, we offer precious metal testing by the fire assay method.


What is the Fire Assay Method?


Fire assay is a standard procedure used industrially to procure gold and platinum group element (PGE) concentrations from different samples. There are two types of fire assay tests. 


Lead Collection Gold Fire Assay:


It is one of the precise techniques available for gold analysis which can accurately determine the content of platinum and palladium. Usually, this kind of assay is more suited to detect gold in almost all types of samples including rocks, drill cores, soil, and chip samples. 


Nickel Sulfide Collection Fire Assay:


This kind of fire assay can best detect all the PGE six-element suites.


Our team of experts is accustomed to dealing with various kinds of samples in different shapes and sizes. We can help you choose which type of fire assay to choose depending on your sample type and sizes. We can also offer our clients multiple sizes of samples ranging between 15g, 30g, and 50g. We are determined to offer our customers competitive expertise in gold and other precious Metal testing in Chennai so that you get nothing but the best. 


Steps of Fire Assay Method


The three major steps of the process are as follows:


Fusion:


  • The sample is ground and mixed with a fluxing along with lead. After about 20 minutes at 1000 degrees, the precious metal and lead separates to form a button. 
  • Precious Metal Extraction: The precious metal is separated by cupellation to form a metal bead.


Detection:


  • Precious metals can be detected by various methods-
  • Flame Atomic Absorption (AA)
  • Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES)
  • Inductively Coupled Plasma-Mass Spectrometry (ICP-MS)
  • Instrumental Neutron Activation Analysis (INAA)


As one of the NABL (The National Accreditation Board for Testing and Calibration Laboratories) accredited labs in Chennai, we also offer analysis of 99.99% high pure gold for hallmark assays. As one of the best Gold testing Labs in Chennai, we provide our clients with reliable and quick precious metal tests for a seamless and easy product launching process. Contact us today to learn more about the tests and deals available at our labs.

What is Animal Feed testing ?

Animal feed testing labs in Chennai analyze samples of animal feed to assess their nutritional composition, quality, and safety. Here's an overview of the process involved in animal feed testing: Sample Collection: The first step is to collect representative samples of the animal feed to be tested. Samples should be collected following proper sampling procedures to ensure accuracy and reliability. Preparation of Samples: Once collected, the samples may need to be prepared or homogenized to ensure uniformity and consistency. This may involve grinding, mixing, or sub-sampling the feed samples as needed. Selection of Testing Parameters: Depending on the specific requirements and objectives of the testing, various parameters may be analyzed, including: Nutritional Composition: This includes testing for moisture content, protein content, fat content, fiber content, carbohydrate content, and mineral content. Contaminants : Testing may be conducted to detect contaminants such as afla...

What are the symptoms of vitamin A deficiency?

Vitamin A deficiency can lead to a range of symptoms, and its severity can vary. Vitamin A is crucial for various bodily functions, including vision, immune system function, and skin health. Here are some common symptoms of vitamin A deficiency: Night Blindness: One of the earliest and most characteristic signs of vitamin A deficiency is difficulty seeing in low-light conditions or night blindness. This occurs because vitamin A is essential for the synthesis of rhodopsin, a pigment in the eyes that helps with low-light vision. Dry Eyes and Xerophthalmia: Insufficient vitamin A can lead to dryness of the conjunctiva and cornea, causing a condition known as xerophthalmia. In severe cases, it can lead to corneal ulcers and blindness. Skin Changes: Vitamin A plays a role in maintaining healthy skin, and its deficiency can result in various skin issues. Dry, rough skin, as well as the development of follicular hyperkeratosis (thickening of hair follicles), may occur. Impaired Immune Functio...

The Attenuated Total Reflectance (ATR) technique is used in FT-IR spectroscopy

Attenuated Total Reflectance (ATR) is a powerful measurement technique used in FT-IR spectroscopy. Let’s explore its applications and how it works: 1. Identification of Chemical Compounds:  ATR-FTIR spectroscopy helps identify chemical compounds by analyzing their unique infrared absorption patterns.  It’s particularly useful for characterizing organic and inorganic materials. 2. Studying Molecular Structures:  ATR provides insights into molecular structures, including functional groups and bonding arrangements. Researchers use it to investigate polymers, proteins, and other complex molecules. 3. Surface Properties Examination:  ATR allows surface analysis without extensive sample preparation.  It’s valuable for studying thin films, coatings, and interfaces. 4. Analyzing Polymers:  Polymer characterization benefits from ATR due to its ability to analyze solid samples directly. Researchers study polymer composition, additives, and degradation. 5. Biomolecule...
