SGE has evaluated each ASTM and EN biodiesel method to demonstrate the suitability of BPX-BIOD GC columns to achieve optimal separation. Each BPX-BIOD GC column is tested at the maximum operating temperature for the column, and specific tests are undertaken to ensure the column meets inertness specifications and separation performance. This means you can be confident of a reliable separation, column after column. Please ask for Biodiesel Analysis Toolkit guide.
