Chemical Testing and Analysis

Expert chemical testing and analysis services including composition analysis, trace contamination detection, metals testing, identification of unknowns and regulatory testing.

Chemical testing and analysis are vital for regulatory compliance and to understand the quality and composition of chemical substances and materials that are used in products, industrial and manufacturing. Advanced analytical instrumentation or a combination of techniques is necessary to solve problems or determine composition.

We provide advanced research and testing expertise and Good Laboratory Practice (GLP). We perform testing protocols according to standard methodologies (ISO, EN, BS, ASTM, etc.) and are experts in developing tailored analytical methods and performing method validation for specific testing applications.

Chemical Composition Analysis and Testing

Our chemical composition analysis utilizes a combination of techniques that can cover a wide range of applications, and which determine chemical quality, identity, composition and impurities.

Chemical composition testing and analysis of samples, mixtures of substances, or unknown substances.

Accurate analysis of the chemical composition of a product or material will provide invaluable information, assisting chemical problem solving and ensuring the quality of a chemical formulation or product.

Chemical composition analysis can require the application of a combination of analytical methods in order to achieve a full picture of the chemical structures and concentrations of the components in a sample. To aid product development, the concentration of specific components, such as an active ingredient which impart a unique function to the product, should be determined in order to understand the product's performance or quality. Obtaining reliable impurity profiles can also assist with product development and resolve manufacturing issues.

Our chemistry unit laboratory test samples, materials and products for chemical composition and impurities. We are focus in determining the chemical composition of a sample, trace analysis, elemental analysis, and trace metals testing.

We apply our services to providing composition analysis serving a wide range of sectors and sample types including chemicals, consumer products, cosmetics, pharmaceuticals, polymers, packaging materials and more.

Chemical Composition Testing:

Chemical Trace Analysis

Chemical trace analysis is often complex. Our trace chemical testing services include trace metals analysis and organic compounds with detection down to trace and ultra-trace ranges, even for complex sample matrices. Chemical residues testing includes analysis, detection and identification of residues.

Chemical trace analysis testing for industry covering identification of unknowns and trace residues, contamination detection and forensic analysis.

Quite often, the compounds of interest will be present in trace or ultra-trace levels which can give rise to analytical challenges, especially when it involves complex sample types.

Our chemical trace analysis services deliver credible results, employing highly sensitive instrumentation and specific analytical methods which are capable of analysis to very low levels of detection, including in the parts per million (ppm) and parts per billion (ppb) ranges although this can be sample-dependent. NCTE laboratories detect, identify and measure trace amounts of chemicals in products and materials down to low-trace and ultra-trace levels.

Chemical residue analysis studies include the identification of unknown substances, diagnosing and resolving contamination incidents. We deploy a wide range of identification techniques for residue trace analysis that includes mass spectrometry, chromatography, spectroscopy and other advanced instrumentation.

Chemical trace analysis capabilities:

Elemental Analysis

Using a wide range of elemental analysis techniques, our scientists can identify and quantify the elemental composition of chemical samples and compounds. Sample types include organic and inorganic analysis and aqueous or non-aqueous materials. Our experts use a variety of techniques, from semi-quantitative to fully quantitative methods, to identify and quantify the elemental composition.

Elemental analysis, identification and quantification of elemental composition to trace and ultra-trace levels for a diverse range of samples.

Elemental analysis and testing include identification and quantification of elements in a sample, determination of the elemental composition, and trace level elements.

A highly-skilled approach to elemental analysis is required that combines appropriate instrumentation with sample preparation and methodology that are most relevant to both the sample matrix and the aim of the study. The ability to work to relevant standards is essential.

We apply our services in elemental trace and ultra-trace analysis to parts per million (ppm) and parts per billion (ppb) levels, using proven techniques for sample preparation and sample analysis.

Our laboratories utilize a range of up-to-date instrumentation including Atomic Absorption spectroscopy (AAS) and Graphite furnace system which detects trace levels through to percentage levels. Sample types and matrices tested for trace elements include organic and non-organic, aqueous and non-aqueous materials.

  • Aluminium, Arsenic
  • Cadmium, Carbon, Chloride, Chromium, Copper
  • Iron, Iodine
  • Lead, Mercury
  • Nitrogen, Nitrogen Species, Nickel
  • Phosphorous, Potassium
  • And many more Elements and Elemental Compounds
Agricultural Commodities Testing and Analysis

We provide agriculture laboratory testing for every step from seed to harvest. We perform the latest analytical testing on grain, fruit, poultry, soil, and water for a wide range of farms.

Whether you're a backyard farmer, family farmer, or you run a commercial farm, testing certain elements of your landscape require testing to ensure safety and optimal growth. NCTE laboratories survey major parts of your farm for a variety of integral purposes:

  • Soil: The objective of soil analysis is to inventory the soil's levels of nutrients and its chemical composition. If your soil's nutrients are off their baseline, your crops could suffer from damaged yields or even fail to grow properly. You can solve this with nutrient solutions and lime applied in an environmentally friendly way. NCTE will perform a deep soil analysis to help you control your costs, maximize returns, and protect the environment
  • Compost and Manure: Compost is an essential piece of farming, used alongside soil to improve both soil structure and nutrient content. Manure can also add essential nutrients to feed your crops, reducing the need for commercial fertilizers and nutrient solutions. Materials used for composting and manure must be tested for safety precautions
  • Fertilizer: For manufacturers of fertilizer all along the supply chain, quality testing ensures products exceed quality and content specifications. NCTE will help make sure both the raw ingredients and final product meet your standards and those of farmers
  • Water: While not everyone thinks of water as a nutrient, it's the most essential one for plants. NCTE's comprehensive water analysis will help determine the suitability of your water supply for farming or household usage. We'll provide a microbial count (should be linkable to Microbiology unit page), breakdown of minerals, and all the essential data you need

Make sure you get the tests you need for GAP standards and to meet food safety requirements.

Trace elements, elemental compounds and species detected and characterized:

  • Soil Tests
    • Macro/Micro Nutrients
    • Organic Matter, pH
    • Food Safety and Environmental Tests
    • Pesticide Residue
    • Heavy Metals
    • Microbiology (should be linkable to Microbiology unit page)
  • Water Tests
    • Macro/Micro Nutrients
    • E. coli/Coliform (should be linkable to Microbiology unit page)
    • Nitrates/Nitrites
    • Lead & Copper

We'll work with you to determine the testing you need for your agricultural products and create a custom analysis for your needs and goals.
