Laboratory Equipment & Services Information System by Centralized Laboratory Management Office (CeLMO)

ICP-OES is a laboratory technique used to detect and measure the amount of chemical elements in a sample.

In ICP-OES, the sample (usually a liquid) is introduced into a very hot plasma (ionized gas). The high temperature excites the atoms and ions in the sample, causing them to emit light at specific wavelengths. Each element produces its own unique light signature. 

Requirements to send sample(s):

1. Samples are usually liquid and must be dissolved and filtered before analysis.
2. Each sample require a minimum volume of 15ml and clearly labelled.
3. Samples need acid digestion before testing.
4. Strictly no urgent samples.
5. Equipment/slot booking must be made through lesis@usm.my
6. Please contact person in-charge for further information (Pn Wan 012-4653800)

ICP-OES is widely used in environmental testing, food analysis, pharmaceuticals, geology, industrial quality control and clinical and biological research because it can analyze many elements at the same time with high accuracy and sensitivity.
