TCR caters to all analytical requirements for Ferrous, Non-Ferrous Metals, Ceramics, Glass, Refractory, Minerals and Ferro Alloys. The chemical department analyses samples in all forms including drillings or turnings, solid samples, and liquids.
The Classical Wet Chemistry (bench chemistry) Department uses Gravimetry (chemical species is determined by weighing) and Titrimetry (involves volume measurement of a liquid reactant) procedures to analyse the chemical composition of materials. It assists in the identification of unknown materials and gaining an understanding of their chemical composition, structure and function. Most classical wet chemical methods can accommodate comparatively small amounts of a sample in diverse shapes or forms. Fully compliant with the environmental standards of India, the wet chemistry department at TCR is highly sought-after by leading companies all over the world, right from trace chemical analysis to very low detection levels.

Equipment
TCR Engineering has a wide range of equipment that is available for chemical analysis:
Spectrometer:
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 analysed 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, aluminium 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.
Representative engagement. Casale SA, Switzerland, urea and melamine licensor, approved under vendor code 1000007973 on the SX3000 schedule (June 2025).

Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) for multi-element scanning. Combustion Analysis (LECO) for carbon and sulphur. Inert Gas Analysis (IGA) for nitrogen and oxygen. Classical wet chemistry for verification and arbitration analyses.
Glow Discharge Spectrometry (GDS) for surface and depth-profile analysis, Energy Dispersive X-ray (EDAX) micro-analysis, and X-ray Fluorescence (XRF) for portable and bench alloy identification.
