The analyzes offered in this section are suitable for groundwater samples used in mineral exploration, but NOT for salt water, brines, effluent solutions and metal-carrying solutions generated in processing circuits or environmental applications. Requests for environmental services will be forwarded to an SGS Environmental Services Laboratory.
SGS has considerable experience in the preparation and analysis of a wide range of vegetation samples. Such samples may be dried and macerated or ashed prior to acid digestion and analysis by ICP-OES (GE_ICP23D50) and ICP-MS (GE_IMS23D50).
