Location: ACMS 101

Instrument: X-Ray Fluorescence Spectrometer
Model/Supplier: Rigaku Corporation, Japan

Rigaku made WD-XRF Machine(power:- 4KW,60kV-150mA) is used for detecting the elements. It is a non destructive analysis technique for the Major oxides and Trace elements present in the sample with minimal sample preparation requirement. It can cover elements from Beriliyum to Uranium. The concentration ranges goes from 1ppm to 100wt%. Analysis can be done on pressed powder pellets or Glass beads(ranging from 10mm diameter to 30 mm diameter) made from fine powder(particle size-50µ).


Basic application is to quantify the elements in metals & alloys, Geological samples,Chemicals(Raw & prepared),Filter samples,Thin films,Ceramics etc.

Instrument: Claisse M4 Glass Bead Making Machine

Claisse M4 is a machine used for prepartion of Glass Beads by the use of flux & sample. This technique uses minimal sample(1gm) which is prepared by fusion and preparing homogenized glass disks, which eliminate particle and matrix effects,resulting high analytical accuracy.

Instrument: Stable Isotope Ratio Mass Spectrometer(IRMS)
Model/Supplier:Thermo Scientific Delta V advantage IRMS;Flash EA-2000; Conflo IV universal Interface; Gas Bench II System

The mass spectrometry facility is equipped with a delta V advantage. Stable Isotope ratio massspectrometer(IRMS) coupled with an Elemental Analyzer Flash EA2000 and Gas Bench II sample preparation device to perform continuous-flow high-precision stable hydrogen( δ2H), oxygen( δ18O), carbon( δ13C), andnitrogen( δ15N) isotope ratio analyses on a variety of inorganic and organic samples including carbonate sediments, soli, water, plants, organics, aerosols,atmospheric gases, archaeological materials, animal tissue, bone collagen, etc.


The Elemental Analyzer , and Gas Bench devices are used for on-line extraction of gas-phases from samples and introduction of the purified gases directly into the ion source of mass spectrometer for stable isotope ratio measurements. The elemental Analyzer with an automated solid sampler is used to combust solid inorganic/organic samples in continuous-flow for δ13C and δ15N analyses. The Gas Bench II system is used for temperature dependent carbonate-acid reaction and extraction of CO2 gas, which is subsequently measured for δ13C and δ18O values. This system can also be used for carbonate samples, gaseous species, dissolvedinorganic carbon, and for water isotope( δD and δ18O).
