That is the reason why conventional AFS and AAS methods include sample digestion by acids and require compressed gases such as argon or oxygen. This makes analysis more complicated and costly and extends analysis time. Sample pre-treatment can also increase measurement errors. The use of a RA-915M/RA-915M+ mercury analyzer with a PYRO-915+ pyrolytic attachment or RA-915F mercury ?nalyzer provides direct mercury determination in foodstuff, food/feed products and ...

The shipping industry is continually experiencing regulatory changes driven by increasing environmental concerns, resulting in ever-tightening regulations restricting sulfur (S) emissions from ships' fuel. It has been announced by the UN's shipping agency that the new sulfur IMO 2020 (International Maritime Organizations) guidelines for the sulfur content of marine fuel (bunker fuel) at sea will drop from 3.5 wt% to 0.5 wt% in early 2020. The sulfur content of traditional bunker fuels used in the shipping industry ...
