- recycling of GaAs, GaP and other Ga related scraps (contaminated with water, oil, boron oxide,
pBN, epoxy, cement, alumina, etc.) with min Ga content 5 %

- our own proprietary technology is waste free

- refining of Gallium to 4N (99,99 %), 6N (99,9999 %) or 7N (99,99999 %)

- a unique technology for removing Germanium from Gallium down to 10 ppb wt

- typical yield from GaAs to Ga process is 97 % and 99 % from refining Ga 4N to 6N or 7N

- short turnaround is platitude

- each lot is analysed for purity by GDMS and a certificate is enclosed

- packaging according to IATA regulations in certified boxes and PE bottles filled under pure nitrogen
