TMP Pumping System and Column
The internal diameter and length of a column affects vacuum pressure. Using the column of larger internal diameter makes carrier gas flow larger and requires a more powerful and more effective evacuating system. The table shows a rough estimate between the pumping capability and the column limitation from the view of the vacuum.
