Atomic Absorption (AA) Graphite Furnace Spectrometer
The sensitivity of GFAA enables performances of elemental analysis that are 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 (ICP) Spectrometer
ICP is a spectro photometic 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, makes these the most flexible instruments available today with parts per billion detection limits.
Optical Emission Spectrometer (OES)
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. Relatively simple sample preparation allows rapid turnaround of results using this technique.
Glow Discharge (GDS) Spectrometer
Similar to OES, GDS is used extensively for metal analysis. The straight line calibration similar to ICP makes this technique particularly attractive for the analysis of stainless steel, nickel, aluminum and copper alloys.
Atomic Combustion; Carbon & Sulfur
Combustion carbon and sulfur determination is accepted as the most accurate method for determining carbon and sulfur in metal, ore and powder samples. These samples may be in the form of solid material, drillings or powders. This technique is used mainly to complement ICP or OES analysis for the full chemical analysis of metallic samples.
NABL Scope of Accredition
National Accreditation Board for Testing and Calibration Laboratories (NABL) is an autonomous body under the aegis of Department of Science & Technology, Government of India providing laboratory accreditation services to laboratories that are performing tests/ calibrations in accordance with IEC and ISO 17025 standard. Presented below are the NABL Scope of Accredition at TCR Engineering Services.
