High Resolution Inductively Coupled Plasma Mass Spectrometry (HR-ICP-MS) is an analytical technique used for elemental determinations. We are equipped with a Thermo Scientific ELEMENT XR, a high performance, double focusing magnetic sector field ICP-MS. Aerosol samples are transported into the core of the inductively coupled argon plasma which generates temperatures of 6000-10000 degrees C, where they are completely desolvated and ionized. The resultant ions are separated and collected by mass to charge ratios. The system can detect element from Lithium to Uranium except the noble gases and the elements which do not get converted to positive ions (F).

1. Sample should be submitted in solution form specifying the elements to be estimated and their approximate concentrations expected, but the Total dissolved Solid in the solution should not exceed preferably 500 ppm. 2.Generally 10 ml of solution is sufficient for estimation of about 10 to 15 elements 3.For special samples like rocks / ore samples, appropriate standards along with the samples should be submitted by user. 4.Explosive, poisonous samples and samples giving rise to toxic gases/fumes cannot be undertaken for ICP-MS analysis. 5.There is no upper limit for the number of samples acceptable for ICP-MS laboratory. 6.The nebulizer of the instrument is made out of PFA material, but spray chambers are of Glass, quartz and PFA, hence user should specify if their samples have HF content. 7. The concentration of analyte in samples should be less than 100 ppb for ICPMS. 8. Kindly provide the standards for e.g. rocks so that Matrix interferences can be avoided. |
