2. INTRODUCTION

3.  measures the light emitted at element-specific
characteristic wavelengths from thermally
excited analyte ions .
 light emitted is separated and measured in a
spectrometer, yielding an intensity
measurement that can be converted to an
elemental concentration by comparison with
calibration standards.

4. Mass spectrometry (MS)
 2 type - determination for element
having unit PPB-PPT
Optical Emission Spectrometry
(OES)
- determination for element
having unit PPM-PPB
Gas used:
 helium and argon
Calibration- Manganese
Radial – 10PPM
axial- 1PPM

5. Part of machine

8. 3. Pump

9. 4. Chamber

10. 5. Nebulizer

11. 6. Flame injection

12. 7. Torch

13. 8. Axial / Radial

14. 9. Spectrum
 Selection of colour for each element.
 Convert into energy Eo
 Transfer into computer- calculate intensity,
log10 = 1/Eo

15. Can analyze 43 element in the periodic table
except for nitrogen and oxygen
 Eg: Phosphorus P, Potassium K, Sodium Na,
Boron B, Calcium Ca, and etc.
Error of ICP : 0.05%

17. Calculation
 Run standard
P, K, Mg, B
 Plot graph.
 From graph, calculate slope, m
 Formula, y=mx + c
 Calculate intensity
 Calculate ppm, formula
PPM= (intensity-intercept)/slope
