(fusedsilica)
• Linearity for all reference compounds exceedsmethod requirements.
• Alumaseal® connector provides leak-free connection; guard column
extends column life.
• Low columnbleed at high temperatures.
• For glycerine and glycerides analysis, according toASTMD6584 and
EN14105methods.
*Total column length= 16meters.
**Connectedwith low-dead-volumeMXT connector.
