Chemical analysis laboratories are a critical resource for both material and product manufacturers as they provide essential third-party technical data and analysis services. Chemical analysis is used to identify the contents, composition, and quality of the materials used in product development, manufacturing, and in-service support activities.
Why chemical analysis?
Chemical Analysis is useful for:
Manufacturers across all industries rely on material verification services to ensure that the material they are utilizing has a chemical composition consistent with their materials certification documents. Element provides clear and concise test reports that state the results of the chemical analysis along with a comparison to the acceptance criterion (pass/fail).
This allows manufacturers to “spot check” material lots and often serves as an investigatory first step for warranties and issues related to in-service failures.
Sometimes, the identity of a material can be completely unknown, due to lost certifications or ambiguity over the material’s origins. In these cases, Element’s chemists utilize their chemical analysis expertise to select numerous analytical techniques and perform advanced data analysis to uncover the complete chemical breakdown of a material.
This allows Element to identify any material recovered from the field, salvage unknown material that would otherwise be scrapped, and reverse engineer or deformulate existing materials, products or components.
Chemical composition analysis
Element's chemical analysis teams utilize a combination of techniques to identify the chemical composition, determine chemical quality, and identify any impurities.
Our range of services includes employing Arc Spark-Optical Emission Spectrometry, Combustion, Inert Gas Fusions, and various other wet/classical methodologies; analysis of bath solutions for electroplating, cleaning, and etching or pickling; and checking raw materials (metal bars/sheets used in manufacturing and processing) for conformance to the required specification to ensure that the products are suitable for their intended purposes, e.g. strength, corrosion resistance, and toughness.
Contaminant detection & residue analysis
When a residue or an unknown substance appears where it should not, identifying the contaminant quickly and accurately is crucial to correcting any underlying issues.
Element’s investigative chemical analysis teams have a wide range of equipment and techniques at their disposal, including SEM/EDX (Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy), XRD (X-Ray Diffraction), and FTIR (Fourier Transform Infrared Spectroscopy).

Brunauer-Emmett-Teller (BET) analysis provides precise specific surface area evaluation of materials by nitrogen multilayer adsorption measured as a function of relative pressure using a fully automatedanalyzer.
Barrett-Joyner-Halenda (BJH) analysis can also be employed to determine pore area and specific pore volume using adsorption and desorption techniques.This technique characterizes pore sizedistribution independent of the external area due to the particle size of the sample. Element's laboratories in Asia are equipped with Micromeritics TriStar II for this analysis.
We are equipped with an elemental analyzer that analyses Nitrogen according to the DUMAS combustion principle and measures simultaneously Nitrogen and Total Carbon from a single analysis. The Inorganic Carbon is measured by the Acidification of the sample.
The Organic Carbon is calculated by difference (TC-IC) or measured as NPOC after pretreatment by acidification of the sample. The analyzer provides fast, accurate, and low-level analysis for these parameters in applications such as soil & plant, sludges & sediments, animal feed & grain, food, malt, fertilizer, etc.
Pyrolysis-Gas Chromatography (Py-GC) allows the analysis of small amounts of polymeric samples in a wide variety of forms including insoluble and composite materials without pretreatments and provides unique information that otherwise cannot be obtained.
Py-GC is a very useful and powerful analytical technique for polymer characterization. One of the applications is the determination of the silane concentration of the silane-treated concrete for quality control of surface protection.
Ion chromatography (IC) is the separation and quantitative analysis of anions in an ionic solution using the analytical column. The chromatographic process separates the different ions within the sample. The amount of an anion is measured by the change in conductivity as the species passes through the detector.
Anions like Fluoride, Chloride, Nitrite, Bromide, Nitrate, Phosphate, Sulfate, and Iodide can be analyzed using IC.
Besides the C/N analyzer, we also have TOC and TN analyzer for different types of water analysis. The Shimadzu Total nitrogen module TNM-1 uses chemiluminescence to measure total nitrogen in minutes. NPOC, IC, TC, and TOC (TC-IC) measurements are also possible with the combustion catalytic oxidation/ NDIR method.
