Atomic Absorption (AA) Graphite Furnace Spectrometer

The sensitivity of GFAA enables performances of elemental analysis that is virtually impossible using other analytical techniques. These are used to determine ppm and sub-ppm levels of residuals in metals. GFAA is also particularly useful for the determination of low boiling point tramp elements in aerospace alloys. This method is particularly pertinent in material analysis for the detection of trace metals.

Inductively Coupled Plasma Spectrometer

ICP is a spectrophotometric method carried out in solutions where high temperature argon plasma is used to reduce matrix effects, giving straight-line calibrations. This enables low sample weights to be analyzed and coupled with its wide calibration range making them the most flexible instruments that are available today with parts per billion detection limits. 

Optical Emission Spectrometer

These instruments enable the rapid quantitative determination of a wide range of alloys including carbon/low alloy steels, stainless steels, cast irons, aluminum alloys, nickel alloys and copper alloys. It entails a relatively simple sample preparation that allows a rapid turnaround of results using this technique.


X-Ray Diffraction Spectrometer

X-Ray Diffraction Analysis (XRD) investigates the crystalline material structure, including atomic arrangement, crystallite size, and imperfections. The X-rays are generated by a cathode ray tube, filtered to produce monochromatic radiation, collimated to concentrate, and directed toward the sample.

Combustion carbon and sulphur determination are accepted as the most accurate methods for determining carbon and sulphur in metal, ore or powder samples. These samples may be in the form of solid material, drillings or powders. This technique is mainly used to complement ICP or OES for a full chemical analysis of metallic samples.






TCR Engineering has a wide range of equipment that is available for chemical analysis: 




Ferrography or oil analysis, is a series of laboratory tests that determine the condition of used lubricants in equipment components, over a period of time. A trend of Wear Particle distribution and their concentration typically presents the condition of the equipment. It allows organizations to be proactive as it provides them with the opportunity to be prepared for investing in maintenance programs for breakdowns.

There are six basic Wear Particle types generated through the wear process, which includes metallic particles that comprise of Normal Rubbing Wear, Cutting Wear Particles, Spherical Particles, Severe Sliding Particles, Bearing Wear Particles (Fatigue Spall Particles, Laminar Particles) and Gear Wear (Pitch Line Fatigue Particles, Scuffing or Scoring Particles).  Sand and dirt particles responsible for generating Wear Particles exist in the system too.

RoHS Compliance Testing

RoHS Compliance Testing

The RoHS Directive states that certain non-exempt products, as well as electrical and electronic products available in the market within the EU, must contain less than 0.1% lead (Pb), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE), and less than 0.01% cadmium (Cd). Product manufacturers including computer hardware, IT equipment, clock radios and toasters could find themselves banned from selling their product in the European market if they fail to comply with the new directives.


TCR Engineering Services has devised testing programs to help clients understand the rigorous RoHS restrictions. TCR has researched complex methodologies required for compliance testing and has acquired specialized equipment to meet client needs. The RoHS Testing Team at TCR has the capability to analyze all restricted substances up to the required limits and they ensure that the products meet all the requirements while retaining full product functionality.

  1. Restriction of (certain) Hazardous Substances (RoHS) is a result of Waste Electronic and Electrical Equipment (WEEE) Directive, which addresses end-of-life issues on electrical components

  2. The WEEE Directive is essentially concerned with the introduction of hazardous materials into the environment, during recycling or disposal

Lead Inspection


The RoHS Testing Team at TCR analyses concentrations of lead, mercury, cadmium, chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs) in electrical and electronic components, right up to the required limits, to ensure that all the products meet the requirements while retaining their full functionality. TCR Engineering Services undertakes RoHS and WEEE-related compliance testing for electronic products and accessories using both:


Non Destructive RoHS screening (RFA method)

The screening provides indications about the presence of hazardous substances in the product according to RoHS. It is best suited to gain a quick overview of a goods receipt check or in preliminary inspections. Using a custom-tailored portable X-Ray Fluorescence Spectroscopy (XRF) spectrometer, the inspection team from TCR can simultaneously screen for all five restricted RoHS elements and chlorine (Cl), in a matter of a few seconds. Using a Portable XRF is non-destructive and an in-situ point-and-shoot screening method for PVC, PE, alloys, metals, solders, ceramics and packaging materials.  


Chemical Analysis by ICP (Verification method)
RoHS testing is carried out using an initial screening test by XRF; if high levels of restricted substances are found, additional tests may be performed using Inductively Coupled Plasma (ICP) Spectrometer and wet chemistry. The Chemical Analysis Department at TCR provides all its clients with accurate, precise results that report the total level of RoHS elements and compounds, along with detailed information about their products meeting all RoHS requirements.


Lead Inspection and Detection

The ill-effects of Lead (Pb) consumption is gaining significance all over the world. The Lead inspection service from TCR allows manufacturers of consumer electronics materials, children's toys and jewelry, cooking or edible materials, packaging, and several other materials in India, to create lead-free landfills and clean up hazardous sites. TCR Engineering Services undertakes the classification of definitive positive/negative results for Pb using portable XRF instruments.


TCR’s XRF instrument can detect the presence of lead in paints & coatings, as well as in oils & liquids. The tests are done in-situ and it can help in establishing area contamination boundaries and depth profiles, including assisting in site investigations, delineation and contamination patterns.
