Rtx®-Biodiesel TG Columns
(fused silica)
• Linearity for all reference compounds exceeds method requirements.
• Alumaseal® connector provides leak-free connection; guard column
extends column life.
• Low column bleed at high temperatures.
• For glycerine and glycerides analysis, according to ASTM D6584 and
EN 14105 methods.
*Total column length = 16 meters.
**Connected with low-dead-volume MXT connector.
MXT®-Biodiesel TG Columns
(Siltek® treated stainless steel)
• Fast analysis times and sharp mono-, di-, and triglyceride peaks.
• Stable at 430 °C for reliable, consistent performance.
• Integra-Gap® built-in retention gap on 0.53 mm ID column eliminates
column coupling completely.
