Restekâs unique Siltek® surface deactivation is used in combination with stainless steel capillary tubing to make the MXT®-Biodiesel TG column line. These columns are specifically tested for use in the analysis of total glycerin in biodiesel, assuring that every column meets method requirements. The MXT®-Biodiesel TG column exhibits low bleed at its maximum operating temperature (430°C) and outperforms fused silica columns above 380°C, offering greater inertness and column lifetime.
