WE DESIGN FOR THE FUTURE MECER The MECER process for alkaline etching During the etching process of printed circuit boards, the etchant becomes increasingly loaded with copper. Opti-mum etching performance is achieved when the copper concentration of the etchant is between 140-160 g/l with an equivalent amount of chloride ion and some free am-monia. SIGMA | all4-PCB The Sigma Group stands for engineering with experience for more than 25 years. With the headquarters in Karlstad, Sweden, their product portfolio contains equipment for on-site recycling of alkaline and acidic etching solution.

WE DESIGN FOR THE FUTURE MECER - h24-files.s3.amazonaws.com latest years Sigma Engineering AB has developed the recovery sys-tem for acidic cupric chloride etchant called the acidic MECER. This process is quite similar to the alkaline MECER, on the market since 30 years, also using solvent extraction and electrowinning techno-logy. All the basic closed circuit concepts are essentially the same. Alkaline Phosphatase | Sigma-Aldrich One unit of alkaline phosphatase is the enzyme activity which hydrolyzes 1 mol of 4-nitrophenyl phosphate in 1 minute at +37 °C under assay conditions. Note: According to Moessner et al. 5 units alkaline phosphatase (+37 °C; diethanolamine buffer) correspond to 1 unit alkaline phosphatase (+25 °C; glycine/NaOH buffer.
