Test Method:

• ICP-MS: Inductively Coupled Plasma – Mass Spectrometry

• ICP-OES: Inductively Coupled Plasma –  Optical Emission Spectrometry

• ICP-AES: Inductively Coupled Plasma –  Atomic Emission Spectrometry

* ICP-OES and ICP-AES are the same.

Applications:

• Analysis of trace amount of impurities with very low contents down to 1 ppb level;

• Good for metal and heavy elements, less accurate for light elements like C, N, O, etc.

Equipments:

• ICP-MS: Agilent 7700

• ICP-OES: Agilent 720

Sensitivity:

• ICP-MS, detection limit: 0.001 ppm (1 ppb);

• ICP-OES, detection limit: 0.02 ppm (20 ppb);

• Higher contents > 1000 ppm (=0.1%), please use XRF Testing Services.

——————

* ppm (10E-6): parts per million

* ppb (10E-9): parts per billion

Samples:

Trace impuriy analyses for:
• Ultrapure semiconductors, metal targets, organic solutions, etc;

• Environmental samples, rocks, sea water, dusts, etc;

• Glass, ceramics, rubber, textiles, etc;

• More…

Test Time:

• 7 Working Days
