7. Note: If the oven does not contain tubing to preheat the eluent, it is necessary that the eluent passes ca. 15 cm stainless steel tubing in the oven before entering the column (it is absolutely necessary that the eluent has heated up before entering the column, otherwise peak broadening shall occur).
