Bay Carbon's CVP Process


Bay Carbon offers three levels of CVP processes.

1. High purity - 20 ppm or less *

2. CVP purity - 5 ppm or less (No more than 2 elements may be present. No single element may exceed 1 ppm) *

3. Semiconductor purity - 0.05 ppm or less. **

* Purity testing is performed on an ATOMCOMP 2000 Dual Slit High Resolution DC Arc Spectrometer using a cathode-enriched layer excited by 12.1 amps. D.C. current. The CID (charge injection Device) detector is a single solid-state chip with over 250,000 light-sensitive detector elements (pixels), providing continuous wavelength coverage from 190 to 800 nm. In this method a stallwood jet is used. This apparatus surrounds the electrode with inert gas in order to stabilize the arc and to reduce CN (cyanogens) banding.

**Glow-Discharge Mass Spectrometry (GDMS). Full periodic table coverage (except H)   Allow 7 - 10 business days for testing results.
